The Mosquito Ring Tone: This Adult Can Hear It!

 

 

 

 

 

 

 

 

 

The NY Times published a story on the Mosquito Ringtone (also known as Teen Buzz) this morning. Allegedly inaudible to adults, this 17Khz ringtone has become popular among teens looking to be able to send and receive text messages surreptitiously in class. They even included a sample of the ringtone, so you could determine for yourself whether it's audible or not.

Well, I had no trouble hearing it, and according to the convenient chart provided (reproduced at left), at the age of 42 most people my age can't hear anything beyond 13Khz. Apparently, I am more youthful than I thought…

Wondering what I could hear, I took a quick trip to the NCH Swift Sound website, and downloaded the NCH Tone Generator application. This little tool is used by audio engineers to generate various different kinds of tones ranging from square waves to pink noise to sine waves, and a bunch more. I generated a four different sets of tones at 15Khz, 16Khz, 17Khz, and 18Khz and listened to them, comparing them with the mosquito. The mosquito is a very dirty tone, with lots of noise in it. Perhaps that's because it's been converted to MP3, or perhaps it's not a pure sine wave. In any case, while the allegedly 17Khz mosquito tone is quite audible, I had difficulty hearing a true 17Khz sine wave. The 18Khz tone was inaudible. You can listen to all four WAV files for yourself and do your own comparison. I recommend not turning the volume way up. Despite the fact that they are nearly inaudible, they are still very high energy sound, and my ears were sore after several listenings.

  1. Jeremy Wright Says:

    Alec, I could hear all of the tones you posted except the last one. I’m 26. It was surprising to me that I couldn’t hear the last one, since the previous ones were so clear. Also a little depressing, since I’ve got a great ear for sound (I’ve produced records and such).

    I’ll get over it though ;-)

  2. Alec Says:

    I was surprised at what I could hear, actually. I remember my dad being very tone deaf in the upper registers when I was a kid.

  3. PhoneBoy Says:

    Early thirties and I can hear them all except the 18 Khz sound, which still makes my ears hurt.

  4. Mathew Ingram Says:

    Damn. We’re the same age, Alec, and yet I couldn’t hear a damn thing — not on any of them. I guess I know what that means… too much standing close to the stage at those ZZ Top and Foreigner concerts.

  5. Alec Says:

    :) I think it must have been your taste in music Mathew… I was listening to the Pistols and the Clash…

  6. Jeremy Wright Says:

    Definitely taste in music. *shudder* @ ZZ Top.

  7. Mathew Ingram Says:

    In my defence, I was living in a small town in rural New Brunswick at the time, so I didn’t get access to the Pistols or the Clash until much later :-)

    I still love ZZ Top though — sorry Jeremy.

  8. Glen P Says:

    I am 43 and could hear all notes with ease..I am a migraine sufferer and at all times I hear a high pitch whine..that is why I always have the TV or radio goinmg ..to drown out the sound …but the sound generator was a much lower tone then I usually hear ..

  9. Glen P Says:

    I just downloaded the tone generator…couldn’t find a tone I couldn’t hear ..though some were very annoying ..and some tougher to hear.then the majority

  10. bernadette Says:

    Well i am 9 years old and i can hear all of them its very annoying but i can use my phone in school!!! Ye haaaa!!!

  11. Steven Says:

    I’m aproaching 29 and can hear them all. All my life i’ve been able to hear high pitches (i can hear it when the TV is on standby).

  12. yordi Says:

    i’m 12 years old and i can hear them all except the last one

  13. yordi Says:

    well i’m 13 years old and i can hear them all except the last one

  14. Kelly Says:

    I can hear the mosquito just fine but, the pure sine waves were harder. I could only hear the first and second. More like pressure when listening to the sine waves. Oh yes, I am ancient by kid standards, a graceful 50 thankyou.

  15. kay Says:

    i’m 14 and i can’t hear the last two, but i can hear the mosquito ring. I thought the t.v. on stand-by thing was all in my head, but i guess they can’t hear that either.

  16. Joe Says:

    Have any of you done experiments with it yet? I played it in my school library and really confused some teachers.

  17. max Says:

    I can hear before 16900KHz. 17959 can’t :(( I’m 28

  18. Jake Says:

    I am 22, can hear all but the 18 kHz, it seems as if a lot of people over 25 can still hear the mosquito tone, so whats the big deal its not that big of a break-through.

  19. Jonny "teh" Cheese Says:

    Those of you despairing of your inability to hear the 18kHz tone, I wonder what your transducer is? Many consumer-grade speakers and headphones roll off significantly in those octaves. You might want to try some quality speakers before you consider yourself partiually deaf.

  20. Amideaf? Says:

    I’m 15 and i can only hear 18 [faintly] and lower. also…. Bernadette is 9 and already has a phone? I put it on an ipod and brought it in to school. My teacher couldn’t hear but everyone was laughing so I got kicked out. When I got kicked out I played it through the door and everyone continued laughing. It really pissed my teacher off!

  21. Ms Vara Says:

    Oh my god……..I’m a high school teacher and for the first time I felt embarrased and deaf in front of my kids when they told me about this (on the last day of school). I could not hear any of them except for one. Keep up the great inventions !!!
    Ms. V

  22. Yeah right, I'll give you my name!!! Says:

    I could hear all of them. I’m 13 years old and I knew already that I would be able to, but I went ahead and did it anyways for laughs. I guess keep up the good work, but I don’t really care if you do or not.

  23. Lauren Says:

    I can hear them all. I’m 14.

  24. Dan Says:

    I’m 45 and can hear the ring tone no problem and from a distance too. I’ve avoided loud sounds all my life, wear earplugs when going to the movies, and if seldom use headphones and when I do keep the volume very very low. I can hear the 18kHz sine wav, but not the others although I’m in the tv room with the hockey game on. By comparison, my 33 yr old sister can hear all the sine waves even across the room (with the tv on), and my 36 yr old brother-in-law can only hear 15 and 16 across the room, and the 17 halfway across the room (again, with the hockey game on).

  25. Benjabang Says:

    It hurts my ears.

  26. Alec Says:

    Hey there “Yeah righ…”… just wanted to let you know that I saved you the embarrassment of posting the other two very immature posts you wrote. I deleted them. If you still want them posted, post them again, and I’ll publish them.

  27. Neil Says:

    Hmmm. I’m 35, and I can hear all of them. Whether this ability will make me rich and famous is up for debate. But I can certainly hear the Mosquito, as well as the 4 frequencies above. And I hate loud music. I’m wondering whether the warnings we were given as children about loud music were actually correct…

  28. David Says:

    OK……. I can hear them all and I am 61 !!!! But that’s a very good thing since I am an audio engineer. I have been blessed with very good hearing since I was first tested in my college days, and I test my hearing on a regular basis. But you guys who can’t hear the tones should keep in mind that it might not be your hearing…. it could very well be your computer speakers. Some of the speakers cannot reproduce above about 12k. Try some good quality headphones. BTW, most people reach their peak of hearing at about age 19 and then start a gradual downward slope.

  29. Soubriquet Says:

    I could hear it fine, and I am 48. Could be the distance at which you can hear it is different, though.

    Another possibility: some can’t hear it because they are just a genetic variation, like the “Supertasters” of

    the world…those people identified by scientists who can taste certain things that no one else can taste.

    I think the researchers jumped to the conclusion that it was age because there are age-related declines in

    hearing…that fact does not allow you to conclude that all differences in hearing are due to age. You can say

    age contributes, but you can not say it exclusively causes the difference.

  30. Thomas Says:

    Im 19, listened to all of them and can hear all of then clear across my room (about 12 feet) from my headphones. then went to play with the NCH tone generator and cranked it upto 22khz (max my headphones can process) and still heard it clear as a bell.

  31. Josh Terrill Says:

    I can hear all of them just fine. I am 13 years old. I think this is amazing! I have an idea…If sombody would like to email me
    d4ta13@gmail.com
    I will share it with you. I think it might work…

  32. Judi in St. Louis Says:

    I’m 56 and I could hear all the tones quite clearly.

    Like Glen P who wrote that “at all times I hear a high pitch whine,” I too hear an ongoing buzz at a very high pitch, much higher than the ones posted. I will try the tone generator to see if I can identify the frequency I hear.

    I am also a “Hum” hearer - one of a worldwide group who hears ultra-low infrasound with pulses and beats that we think may be from drilling or other industry, and is sometimes known as the Taos Hum. http://groups.yahoo.com/group/humforum/

  33. C in Cincy Says:

    Thanks for the link to the tone generator! I was feeling exceptionally old (42 next month) because I couldn’t hear any of your samples. After playing around with the tone generator, at least I know I’m not too far off the norm for my age, at least. And I discovered that the persistant ringing in my ears is resonating at nearly exactly 13000. I can hear, just barely, 13773.02–but just enough that I can clearly tell that the pitch is higher than my tinnitus. After that, nada. You may also be amused to know that my dog was totally nonplussed about the whole thing, but the testing drove one of my cats positively batty! She could clearly tell when I was starting and stopping pitches that I had no hope of hearing myself.

  34. >>>>>>>> Says:

    ye i can hear dem im 13

  35. lauren Says:

    I can’t hear 16961 Hz– I just feel a slight change, but I can hear the last, which I find odd. I turned it up and tried again, and now my ears hurt. The mosquito ringtone is like sandpaper on my teeth. I hope any kid who uses that around me is prepared to get smacked by a girl.

  36. M.H. Says:

    Hi, I am living in Japan. This entry was mentioned and linked from one of IT news site in Japan (http://www.pc-view.net/), and I have visited there.
    This topic reminds me my old experience in my childhood. In those years, I was always being bugged by some strange noisy pulse of sound in my ears when I was in places around main streets of my home city. In later year, when I was 17 or 18, I realized that was a supersonic pulses transmitted by traffic sensor set on the top of the electric pole, and I had just understood it natural that all other people didn’t care about such unpleasant noises, simply they couldn’t hear that.
    Today, I’m almost 41 years old, I tested my ears and realized I can hear 16kHz, but cannot hear all higher frequencies. It is shocking, though I could never check how high that traffic sensor’s sound frequency was. Thanks for having your great blog entry here, and helping me having my great memories back.

  37. bob Says:

    I am 37 and heard all of them. ’70s era ZZTop is excellent. Punk is for retards.

  38. Alec Says:

    Welcome to Japanese visitors, and thanks for letting me know where the traffic was coming from, M.H.

  39. Ingrid J. Goddard Says:

    Well, I’m 32 years old and I can hear all of the sounds even the last one! It’s a little fainter than the others but I can still hear it. I work with people of all ages and ethnic backgrounds and we realized that the caucasian women aged 50 and up couldn’t hear the the mosquito and higher, the black women aged 50 and up could hear only the mosquito and the men aged 50 and up of both ethnicities couldn’t hear a thing! So what does this mean?…

  40. Garry Says:

    I’m 32 and I can hear only the first one :(. If you want to try different frequencies on a mobile, go to http://www.mymadcow.com, they have high pitch mp3s for mobiles. Does anyone know which frequency is the highest a human can hear? Around 20 kHz?

  41. Brad Says:

    I can’t even get those mosquito rings to play, when I click on it, it moves to a different page saying this page can not be found

  42. Ashley Says:

    I’m 19, so no surprise that I could hear them all just fine, but the mosquito and the first two others irritated my senses, but the higher two did not bother me so much. Don’t know if that’s significant, or just opinion.

  43. Melissa Says:

    A 9-year old has a cell phone?
    What is this world coming to???

    I’m 16, and I can hear them all just fine.
    My brother played it for my dad on his computer, and he couldn’t hear it.
    So I threatened to set it as my dad’s ringtone on his cell phone so he couldn’t hear his own phone ring. xD

  44. Fsa3 Says:

    Although I can hear them all, I find it harder to hear the 16961kHz than the 17959kHz.
    I’m 18.

  45. CaCo Says:

    I’m 17 and I can hear them all!! ^^.. but now my ears still hurts me!!!!

  46. Kevin Says:

    Does it posible to download this riigner on cell phone ???

    MOSQUITO TONE

  48. Milestones -- Alec Saunders .LOG Says:

    […] It’s been quite a trippy month on the Saunderslog.  Midway through the month I wrote a short piece on the Mosquito Ringtone, which has catapulted traffic into the stratosphere (or, at least, what I consider to be the stratosphere).  […]

  49. MANSOOF Says:

    NICE ! RINGTONES !
    BUT IT CAN HURTS ADULTS HEAR !
    NICE INVENSION !
    KEEP IT UP !

    THANK’S ! ! !

  50. Mozzy Tones - Mosquito Ringtone(TM)- the ringtones only your kids can hear Says:

    […] This guy can hear the Mozzy Tunes, so at least the adults have infiltrated. […]

  51. Katina Mooneyham Says:

    I downloaded this earlier just to test on my 13 year old daughter. She said it gave her a headache. I definitely heard it (not quite 30 though, but I will be in a few months, close enough!). My kids and my husband call me Sentinel Mom though because I hear, smell and see other things that many people do not (not in a paranormal way). It’s just my senses are keen usually.

    The sound gave me a headache! It was quite irritating.

  52. Justin Says:

    man, is it bad that im 17 and cant hear any of them?

    i would say maybe its all the concerts ive been to (seen over 100 bands, and alot more to come…) but i dont think this really has to do with if your deaf or not, but more so just what range your ears are capable of hearing.

  53. kayla Says:

    I’m 14; and I can barely hear the last one. ^^ .. i guess that’s what real loud headphones does to you. I downloaded the software so I could convert it to an mp3 to send it to my phone. Since every other site requires you to pay outraegeous fees just for the tone.

  54. Mike Gerbil Says:

    I’m 22 and could only “hear” the first two, though they all hurt my ears, especially that last one.

  55. Aditya Pratap V. Says:

    I’m 37 year old guy and I could hear all of them. However, they are painfull to the ear.

  56. Riccardo Says:

    Hello.

    I could hear them all just fine, but right now I feel a little bit dizzy and have a headache. Oh, I’m 20.

    >_

  57. soubriquet Says:

    56 years old, a history of plenty of standing in front of speaker stacks at rock gigs, working in noisy environments, power tools, aero engines, gunfire, explosions… So plenty of hearing abuse likely. But I could hear all but the last one, and i was aware of that whilst it played, but as a sensation of pressur, rather than sound.
    And I’ve been a teacher, I’d play a medley of these just to get my revenge on irritating kids!
    Oh, and I’m a different Soubriquet to the earlier poster, So… Hello Soub!

  58. Mark Says:

    At age 56 I could heatr even the 17959 pure sine wave (that last one was a bit faint). They all were uncomfortable to listen to.

  59. ugotslew Says:

    well with a name like that ^ :)
    i’m 18 and i listen to a lot of loud music, but my hearing hasn’t gone yet!

    i could hear all of them except the last one, maybe its recorded bad or something, but next time (if anyone is reading this) turn the volume up just a lil bit.

  60. Nick Says:

    I’ll be 36 in 2 weeks, and I heard all the tones. This really suprises me because I used to be one of those kids who always listened to headphone music to loud.

  61. Chris Says:

    I’m 51 and undergoing gene therapy in a clinical test environment
    for hearing restoration. Via tone sweep my range is still 15.8Khz,
    but the promise of 5 year old ear sensitivity was too hard to resist.
    My range when 12 was 22khz - lets see if this test group I’m in produces any results.
    Its not surprising that the mosquito is audible - its a very dirty tone.
    i think most of the young repliers leaving their proud ‘i can hear it’ replies will be near deaf
    by 30 without precautions. My idea of near deaf is way below functional deafness.
    Earbuds will flatten those young ears within 5 years.

  62. Tempie Says:

    I’m 12 years old and I can hear all of them. I’m going to try it out on my parents.

  63. Tempie Says:

    I read about this in a magazine and I think I realized something!!!
    Outside of a Costco I’ve been to I hear that Mosquito noise. They play it ever other second. Repeatedly. It bothered me so I asked my parents “What’s that noise?” And they said “I don’t hear any noise.” But my little sister heard it. Perhaps that’ what it was, though, they’ve had it for a while now, before I read about it.

  64. Noah Says:

    27 years old and I can hear them all ok.
    Although listening to these sounds does make me feel a little nauseous.

  65. Arrichion Says:

    Well, all people who has normal hearing should be able to hear up to 20kHz. That chart shows how high pitch sound people can hear at 60dB. By the way that mosquito sound is 15kHz not 17kHz and soundclips are not normalized to same level. Generated ones are little bit quieter.

  66. teacher Says:

    I can’t hear them. I have significant hearing loss in bothe ears. This occured when I was stationed in Irag. A very large IED went off near my vehicle. I now teach and I bought every kid in class a Ring Detecting Pen from http://www.elstonsystems.com/prod/cellular_pen_cell_phone_uv_led.html. Kids with the Samsung models are not allowed to bring those into class.

  67. Philip Says:

    I’m 18 and can hear all of the souds, interesting experiment it even hurts my ears i hear em so well!

  68. Koliedrus Says:

    Ditto what Nick wrote aside from age. I’m 42.

    It’s not just about the frequency of the tone, however. Most people ignore high frequency sounds in the same way that they ignore the fabric of their clothes stimulating the nerves of their skin. It takes a conscious effort to pay attention to something we tend to ignore. Loading the tone onto a phone, carrying it and expecting to be called accomplishes just that.

    In the classroom, articles such as this one accomplish much the same for teachers. But I think it’s safe to say that a very small percentage of even the best ears here have actually recognized the tone “in the wild”. It’s not just our ability to hear well that makes the tone so successful at what it’s meant to do; it’s the exploitation of our brain’s natural tendency to filter out extraneous stimuli.

    It’s is very near-fetched to compensate for these shortfalls so that teachers can teach instead of reacting to every buzz in their ear. Simply put, the student needs a device to produce the sound. He/she cannot generate it with his/her voice. (Mariah Carey’s protege’? No. Facial contortions would give it away. That and a screaming classroom with blood coming from their ears.)

    A passive high-frequency detector that measures sudden pulses of sound within a given range could be placed on the teacher’s desk. When the predetermined parameters are met, a flashing red light and low-pitched buzz could alert the teacher to instruct her students to “turn off your phone or lose it”.

    Better yet, three detectors (one centrally located in front of the classroom and one in each rear corner) could be used to triangulate the exact location of the sound. The robot that comes into the classroom to assign homework to the student needs some more concept design work. I’m partial to the wiiiirrrr-clunk. wiiiiirrr-clunk as it approaches the door. Crashing through the walls would be a bit much.

  69. Koliedrus Says:

    Tempie, The sound you and your sister heard at Costco is something that’s been used for years. It’s meant to disperse groups of “kids” from simply hanging out in establishments. I stopped going to a particular Sears store long ago because the shopping experience was less than enjoyable. I wonder now just how many other places don’t get my business because of that whine…

    Here again, I’m 42 and still hear it. Age may have allowed me to tolerate the sound but perhaps they didn’t anticipate the years of conditioning.

  70. Boll Says:

    Well, i am 18 and i could hear all of them pretty easily. But for people who is not able to hear it, you should check if your speakers/headphones are really able to reproduce the frequency generated. Not all are able - ‘generic’ speakers or headphones may not have a broad frequency range (generally they dont), and you could be not hearing it for this reason.

  71. MatthewS Says:

    I’m 36 and am definately hard of hearing in one ear. I could hear:

    Mosquito
    15102 Hz pure sine wave
    16000 Hz pure sine wave

    pretty well in my right ear, but not my left.

    My daughter, who is almost six, could hear them all. We had to play the last one twice though.

  72. MatthewS Says:

    I could hear the provided sample though.

  73. Mike Says:

    I am 40 and can hear the 15KHz and 16KHz tones.

    Has anybody tried the mosquito ringtones at http://www.aubraux.com/mosquito-ring-tones.php ?

    They have some fancy high frequency ringtones and the pure sine wave ones too.

  74. L. B. Says:

    I’m 35 and can hear all of the tones you’ve provided Alec. Thanks for the link to the NCH Tone Generator.
    It seems there is considerable discrepancy between age-related hearing loss as shown in the chart and the replies above. Koliedrus has an interesting point regarding real-world behaviour, however, it doesn’t seem to explain this data since (presumably) the chart is based upon clinical testing rather than the sort of automatic prioritizing to which Koliedrus refers.
    At least some of the mosquito ringtones are not 17 KHz as the ‘original’ is supposed to be; but rather range 1 KHz above and below a main frequency of 15 KHz. (So says my audio software’s spectral analysis of a ringtone I downloaded).
    As for the appropriate classroom response to the tone, rather than a robot I’d be in favour of some spidery-type thing dropping from the ceiling to devour the kid. Gruesome and instructive.

  75. J.D. Says:

    I am 14 and could listen to all of them, my grandfather (65) also could hear all of them, so unless he is a special case, I’d say the story is untrue

  76. Alec Says:

    Love it L.B.! What’s te spectral analysis software you’re using?

  77. Melissa Says:

    yeahh ok so i can’t hear the Mosquito ringtone and I’m 14 so whats that about??

  78. jc Says:

    I must be missing something here. Why would kids use this ringtone instead of just setting their phones to silent/vibrate mode in the classroom?

  79. FireBath Says:

    So let me see if I understand this? Youngsters use ringtones for their celular phones so ONLY they can hear… Now why would they do that? I mean you can’t realy talk to the phone in classrooms right? so what is the use? There is a guy in Japan who invented a device that could kill a cell phone by a touch of a button, so as a teacher you get that plus a ultrasound detector and fry the loosers. On the other hand why would you let them ring whay do you care. If they are annoyng to you just use the cellphone killer.

  80. Steve Says:

    I’m 24 and could easily hear all of them.

  81. Hänni Says:

    I could hear all four, but yeah my ears tickle now.

  82. slugcountry Says:

    I could hear them all easily, unfortunately I think the proggy listed is bugged, since past 18khz it seems to go into a lower tone… I’m curious to see just how high I can go though

  83. Alec Says:

    Hey Sly,

    A drop in the tone on the 18khz signal is probably due to the capabilities of your speakers. I observed the same thing with cheap speakers myself.

  84. Jinx Says:

    My friend and I tried this on mymadcow.com; we could both hear all of these but on the other website I was the only one who could hear 19 khz… My friend’s mom couldn’t hear any of them, and my dad could hear up to 16 khz. Very coo’…

  85. Crystal Says:

    I am 25 and heard up through 17 clearly. The 18 sounded like a faint whining, but it wasn’t as loud as the other three, although it really hurt my ears. I’m glad my students are too young to use cellphones at school.

  86. Squirty Says:

    I could only hear the mosiquito and the first two. But the other two made my ears turn red! :)

  87. john Says:

    Well I had a range of ages here and we all pretty well fit the curve. It was from ouch turn it down to me I can just hear the ring tone. I read the warning about the sound levels to late and 20 minutes later and my ears still hurt…Oh yes I am 48 the 19, 21.

  88. ali Says:

    Umm i’m 12 and i could hear the first two, but not all the rest of them. I dont think this will be very popular cause i mean, not EVERY kid will have the same result i got and not EVERY adult will get the same result as another, and i mean, if i had my cell phone at school and someone texted me, i would not be able to hear that because of like the teacher talking or my class mates talking, or just period cause it would be in my back pack and its not loud enough. I dunno…maybe i’m wrong. ;-|

  89. Andy Says:

    I can hear them all and I am 39…The last one was quite faint, however. I’m loving it…

  90. JohnK Says:

    I could not hear the 18k tone but could hear the others at 34. I used a pair of headphones that should have a frequency response that high. I can easily hear CRT (television/monitor) whine. And I could easily hear the mosquito tone. I agree that it is grating.

    My biggest surprise from all of this is that cell phone ringers can even produce tones this high. I would not expect the hardware makers to bother with speakers that go to 17k.

  91. Greg Says:

    I’m 15 and I can hear all the sounds without any difficulty

  92. AStarhy Says:

    i heard all of them neah and i’m 20.

  93. Dan Says:

    I am 27 and could hear them all… but the 18KHz sound could not be produced by my laptop speakers; I had to break out the earbuds to hear it. I am the youngest person at my office and no one else here was able to hear the ringtone.

  94. Robert Marler Says:

    As with so many other responders, I can easily hear all but the 18K tone. Note: I said easily. I think the problem is likely one mentioned by another responder: the speakers, but, hey, when I want music, I’ve got the hi-fi. By the way, I’m 62. I never listen to rock.

  95. Gary Greene Says:

    Guess I’m just another data-point, but I’m 59 and I know I have hearing loss acquired in the USAF after 8 years service near flight lines (three years with my barracks next to the staging pad). The loss showed on my out-processing physical. _BUT_ I hear all the samples reasonably well EXCEPT the ring tone, which is barely audible in my right ear. Strange. Mkes me think there is something odd about the ring tone.

  96. Kevino Says:

    Eh? Could not hear a thing!But I can hear a real mosquito!

  97. Shirl Says:

    I’m 59 & I heard them all.

  98. Seran Says:

    am 22, could hear each one, but a little trouble on the last. definately heard it though. now to stop my ears from ringing….

  99. Beth Says:

    Couldn’t hear any of them, darn it, and neither could the other mid-40’s person I work with. Too many rock concerts in our youths, i guess. But we can both hear our daughters THINKING ABOUT MISBEHAVING from the opposite end of the house…so I guess that’s worth something!

    But my two 30-something co-workers could hear the mosquito and the 1500. My 23-year-old co-worker could hear mosquito, 15 & 16.

  100. Tom Egan Says:

    I heard the mosquito and all 4 tones and Ill be 54 in Dec. I take event photos and music videos and am often in from of PA’s etc.
    When it hurts I know its really loud and will be distorting the audio in , so I reposition. Loud is fine but once its annoying or painful to the individual you know you are doing permanent damage if you continue without ear protection.

  101. fluter Says:

    I’m 32 and I couldn’y hear any of the tones … a friend of mine (30 yrs old) sais she heard all but the last two *weird*

  102. De Argo Says:

    That was intresting. I heard all of them but the skeeter then I went to the rigntone site mentioned above in the post. and could’nt hear nothing above 13k. Strange, but thats what made it really intresting to me.Either the frequincies are off on this sites samples or the other sites was.
    Still I think that the hearing aid business is gonna boom before long. All these young people riding in cars with 500 watt amps viberating everything within 100 feet.
    Oh, I’m 46.

    Dont worry you old lot!
    Im just a young ‘un at 19 and I cant hear the 18Khz sound and the 17khz is quite quiet.

    Death metal bled my ears! doh!

  109. Paul S Says:

    oh … and whatever happened to putting your phone in your pocket on vibrate? :P

  110. Mike Says:

    Just FYI for the people who mention hearing constant high pitched whines - that sounds like tinnitus, which actually isn’t a hearing issue. Tinnitus is neurological - there is no sound to be heard and it’s not coming through your ears. Conceptually/analogously, you can think of it as in internal feedback issue, though it doesn’t even originate in the brain’s aural “circuitry.”

    Otherwise, this has been interesting. I’m 42 and always had “good hearing” in the ordinary sense of the term. I hear things others don’t or before they notice them - including my brother’s kids - and have excellent (NOT perfect) pitch. Whether it’s my computer speakers or no, though, I can hear the NYT mosquito ring only slightly, and none of the sine waves at all. Will have try it out on better equipment but even still, I suspect I just can’t hear them. Off to play with that tone generator…:)

  111. evan Says:

    this ringtone is great but i cant find a website where u can get it without having to sign up for something or getting spammed. anyone know where i can find it without having to do the above? o yeah im 13. ^_^

  112. Nick Says:

    I’m 28 and could hear them all, so I went and downloaded the same tone generator. Figured out I could hear up to 20khz. Now my head hurts and my eyes are watering tho. Good psychological warfare for the office…. :)

  113. hajir Says:

    I am 17 and i can hear alll of them ,but my freind(same age as me) he cant hear the 17khz,HE use to hear to loud music (skazi,SUY,&….) and we think that is the reason he can’t hear!!!

  114. jim Says:

    i am 15 and i can here all of them and anyone can hear all of them if the sound is turned all the way up on your comp

  115. freddie Says:

    I am turning 13 and can hear all of them clearly my father in 40’s can barely hear the mosquito

  116. Kate Says:

    Im 11 in a few days. Can hear every one except the last. >.>

  117. Kate Says:

    Oh and also I asked my grandpa to listen and he could not even hear the mosquito. Will test my mum.

  118. Nick Says:

    Seems like the mosquito tone really isn’t 17 khz, or that its interspersed with other (lower) frequencies which render it audible to me. I say this because on the pure sine wave tests, I can barely hear the 16 khz sound, and everything above that is inaudible (yet still painful!). I’m 41, and have blasted my ears with high volume rock, guitar amps, etc., for much of my life. I don’t miss the annoying high frequency sounds though–an unintended but pleasant consequence of all the years of hearing abuse!

  119. Britny Says:

    Woot!! Yeak i like heard them all and im 17!!!

    im 12 and i heard it just fine all my friends say it burns or makes their ears bleed etc.
    i personally think it sounds REALLY cool. any way i always hear really high pitches and really low pitches. and to any of you who tyhink im japanese im not. im ganna try to piss off my teachers on monday!!! ^_^

  122. Gaz Says:

    I’m 22 and can hear all the tones from the other side of the room, I wonder if the volume on the speakers makes a difference to those who can’t hear all of them, mines set to a comfortable listening volume, quite low, small speakers built into the monitor

  123. sakura Says:

    i heard them all really clearly, my mom doest though :( im 12 well there still cool. i wonder if they can make them any higher???? if so i wanna listen to them!!!!
    later…

  124. Karnage Says:

    Yah i heard them. And you could make them higher with Audition/Cool edit’s tone generator, but your speaker system isn’t made to reproduce those freq so no….

  134. Brian Says:

    How accurate are the speakers on a computer to the frequencies they are supposed to be creating? In other words, are the computers accurately making noise at the frequencies the links say?
    BTW… 20 years old and heard all of them.

  135. b0b Says:

    That was phenomenal! I’m 20 years old and I couldn’t believe what I was hearing. Is it weird that I hear frequencies like this often? I hear them and I can’t quite figure where they’re coming from. lol =/ I may be mistaken but is that frequency equal to a B-flat in the 9th octave or is it higher?

  136. FATMA Says:

  137. Chopstork » Blog Archive » Can you hear the mosquitos? Says:

    […] Damn, I wonder if I can hear it. This blog post has the tone in addition to some sine wave tones he generated. I couldn’t hear the last couple until I plugged in decent headphones that could produce the sound. Even then the 18kHz is hard to hear for me, but at least I can hear it. Can you hear all of them? If not, a) You’re doing deaf (it’s ok, it’s natural); b) You need new headphones; or c) All of the above. […]

  154. A Long Tail Lesson -- Alec Saunders .LOG Says:

    […] On June 12th I wrote a piece called “The Mosquito Ringtone: This Adult Can Hear It!“.  It’s about a 17Khz ring tone that adults can’t hear, or have difficulty hearing, and it’s now popular with school kids who want to discreetly text in class.  I also included samples of 15Khz, 16Khz, and 18Khz tones so you could compare. […]

  155. Kevin Says:

    Folks, if you’re listening to these tones through earbuds (and you spent less than a $1000.00 on them), they don’t reproduce sounds over 16khz. Buy a decent ($50.00) set of over the ear head phones (sennheiser is a good choice) and you’ll probably hear this stuff, I must say I have to turn it up much louder than I would have in the past. FWIW, I’m 42 and I have tinitus. Unless those in their mid 20’s have been listening to CD’s with teh volume on 10 for the last 10 or 15 years, you probably can hear this stuff with the right speakers/headphones.

  156. cray Says:

    my mom(41) can hear all of theese mosquito sound:(:(:(:(

  157. Grace Says:

    i’m only 15 and i cant hear past 1600.
    wtf mate?

  158. BRups Says:

    Justin, yes it has completely to do with your hearing ability. The fine hairs of your inner ear not only diminish with age, but also with hearing damage from listening to loud noise such as at a concert or being arround loud equipment constantly. The reason that you cannot hear it is likely because your hair inside the inner ear is damaged from the loud music. I listen to loud music in my car and can hear up to 19 KHz. I am 19 and my friend that is the same age as me but doesnt listen to loud music can hear 20 KHz. Baicaly dont fool yourself, loud music is damaging your hearing.

  159. Jennifer Says:

    I am 44 and I can hear mosquito quite clearly (’ve heard that it is men who lose the higher tones from their hearing more readily with age; is this true ?); I can hear the next two, but the 169xxx and 17xxx hz were very faint. Does anyone else feel nauseated after listening to mosquito ? I don’t listen to it with my volume near the limit, but I the sound gets to me, and it does, surreptiously, in a classroom too, where I tend to think there is some annoying high pitch from electronic equipment, but then figure out it’s mosquito from the nausea. I’m not prone to it, e.g. never get seasick, etc. Anyone ?

  167. heather Says:

    I’m 29 and can hear all the tones, my husband is 28 and he always askes me to repeat myself and I told him that I was going to get him a hearing aid if I had to repeat myself one more time but since he can hear all the tones I guess it was just selective hearing!

  168. Sam Says:

    I’ll be 20 in three months, and being a person who runs sound for bands and stuff(which means loads of loud music and screeching feedback) for over a year now, I kinda thought my hearing was going out. I heard every one of those wav samples, though. The tones sounded very thin, but very intense & extremely annoying. It sounds just like feedback to me, and i felt nauseated with a headache. I know someone in his early 70’s who’s a friend of the family, and I laugh at him because he can’t hear the pikepass beep on the freeway tolls.

    I am 32 and I can hear all of them. I could barely hear the last one.

  183. Alec-s Says:

    Hey alec i hope you manage to read this under all the other posts.

    I opened the sample file in audacity, http://audacity.sourceforge.net .Using the plot spectrum dialog i saw that the sound is a pretty clean 15011 Hz sine wave, not the alleged 17kHz. However, the article at http://www.timesonline.co.uk/article/0,,2-2222217,00.html says there is a 15kHz and a 17kHz version.

    That would make the difference for me because my hearing drops off at about 16kHz. I’m 20 btw.

    mp3 compression tends to remove noise (white noise and pink noise and the like) rather than put it in. most mp3 artefacts are holes in the noise that is meant to be in the sound. (correct me if i’m wrong)

    the tv my family got 2 years ago emits loud sounds above 14 kHz both when on and when off. When I play 14983Hz on NCH tone generator i feel like i’m watching tv. Another noise from the ignorably high pitched world is car brakes. they squeak within the range of 12kHz - 15kHz for some reason.

    last of all, the plus and minus button in nch tone generator go up and down at the same rate as the keys on a piano (incl. black keys). if u hav a piano or music keyboard handy u can test that. 440 Hz is an A.

  184. Dean Francis Says:

    I couldn’t hear the 16kHz one but I could hear all the others, even the 18kHz. Is there something wrong with me?

  185. John Just John Says:

    FWIW I’m 45 and can’t hear any of these tones, not even a little bit.

    I downloaded the NCH tone generator and discovered I can’t hear anything over 12 khz, which according to the handy chart makes me 50-59 years old.

    I blame the sound system at clubs like The Channel and Spit in Boston in the late 70’s, and bands like the Sex Pistols and the NY Dolls. Wouldn’t trade any of that to get my high-frequency hearing back.

    Hi Ms.Saunders,

    I am doing an experiment on the effects of sound frequencies on age. Two of my family members should not be able to hear the ring tone but the fact that it is not pure may explain why a couple adults can hear it including you. Could you write back with more information on how these frequencies behave and the effects they have.

    Your truly,

  192. Jon Says:

    Yea, i can hear em all, im 20, my buddie at 21 can hear em all except the last one…

    interesting…but i will never use one of these anoying tones…

  193. Tony Says:

    I am 45 & I can hear all of them although the last one is a ltttle faint. It’s odd as when I was a kid, none of my family could ever hear the high pitched noise from the TV, and my younger brother used to think I was making it up until one day he tried to creep up on me but I heard him doing it by ‘echo sound’.

    In the UK, there was even a brief attempt during the 1970s to use ultra sonics for shop security alarms where they actually left the emitters on during the day. When my mum mentioned to an assistant in a department store that they hurt my ears, he laughed and said that there was a guy that worked in the basement who had the same problem, and refused to go up to that floor.

    It seems odd how selective hearing is even within families.

  194. Nick Says:

    I can hear them all fine.

    My parents can’t hear them.

    They thought I was making it all up when my 12 year old sister came downstairs for a drink or something and kept asking “What is that noise?”

    My parents flipped their shit and said I am tricking them.

  195. Marty Says:

    I’m 17 and I couldn’t hear any of them, maybe it’s time to get my ears checked out. Bit depressing, though I could hear a second or two of the ringtone.

  196. billybob Says:

    One thing that someone mentioned above was the quality of your equipment_

    If you have off the shelf speakers that probably came with 95% of the PCs on the market over the past 10 years - then yeah - who knows what yore hearing_

    Having quality equipment is a more accurate test for starters - but also just because you can or cannot hear the audio listed on this page doesn’t neccesarily mean you’re deaf_ Before anyone decides to get a hearing aid - contact a doctor or hearing specialist and have your hearing checked out by experts in a controlled environment_

    Other things contributing to being able to hear these frequencies from your computer could also be random background noise - the size of the room you are sitting in - the materials surrounding you [as to whether they absorb or deflect sound or cancel it out]_

    So unless you are sitting in doctor’s office or sound booth at a recording studio - don’t think your ears are bad just yet_

    I’m 31 - I heard all 4 posted frequencies and also the mosquito thing_ I had a Tv going in another room loud enough to hear thru a closed door - the outside unit of an air conditioner going - the traffic drriving by out on the busy main road and various people talking_

    Also something to think about - a dog whistle is usually in the range of 16-22 kHz_

  197. Jack Says:

    I’m 46, and I can hear all of them just fine.

  198. Camilla Says:

    Hey, I am 22 and I heard all of them fine.

    I’ve always thought I was crazy, being able to hear the “static hum” from electronic screens and apparatus’.

    My greatest problem right now is that after having listened to the four examples, being in the same room as a TV that is turned on it giving me a major headache - all those pitches!!

  199. Andrew Says:

    I just turned 25 and have to wear earplugs at rock concerts and NYC subway due to overload in my right ear (sounds like a shorted earphone when exposed to loud noise). I have been protecting my ears over the last 15 years with these earplugs. I can hear the first three pretty well. For the last two, I have to put my ear up to my speaker to hear it.

    my science teacher showed me mozzy tones today in class- my teacher couldn’t hear them but all the kids in class thought it was annoying. i just listened to the 17 with VERY low volume and i could hear it. my ears hurt so bad now! if you were wondering i am 12. not bad ey? i’d like to try my luck at 20 but, mabey tomarrow- my ears just can’t take it right now. i wish i had a cell phone. if i did mozzy tones would be my ringtone.

    Hello, I`M 28 AND I HAVE SUFFERED AN EAR PAIN SINCE SOMEONE PLAYED THE MOSQUITO TONE, I JUST WANTED TO SAY THAT THE MOSQUITO TONE GIVES BAD CONSEQUENCES AND I AM SUFFERING FROM AN EAR PROBLEM. THANKS FOR READING ME.

  208. FER Says:

    WHY DO PEOPLE LIKE TO ANNOY OTHERS WITH THAT SOUND? I DON`T GET IT. MY TEACHER GOT MAD ABOUT ME WHEN I PLAYED IT AND TOOK 20 POINTS OFF OF MY GRADES

  209. Greg Says:

    I downloaded the mosquito one and put it on my phone(the others wouldn’t play for some reason)

    i can hear every one but the 17959 Hz which is really annoying because it is just outside my hearing range(i produces noise but not to the point to where i can really hear it)

    I played the mosqito one for my mom and she couldn’t hear it but she got mad cause she though i was pullin a prank but my sister(14) could hear it fine

    at 15 i think this is an intersting site and that this page is truely interseting.

  210. The Mosquito Ringtone, Can You Hear It? « Technogrrrl Says:

    […] By the time most people reach the age of 18, they can’t hear sounds above 16kHz. By the time they’re 30 they can’t hear above 14kHz. I found a handy chart and a link to a free tone generator on Alec Saunder’s blog. He’s another adult who can hear the mosquito tone. I downloaded the tone generator from NCH software and gave myself a little hearing test. I can hear tones up to 20kHz. I ran Steve through the test (he’s 37) and he could only hear up to 15 kHz, which is actually pretty good for our age group. […]

  211. Jordan Says:

    I’m 18 and i sat here listening with my brothers, ages 7 and 10. all 3 of us could clearly hear all of the tones.
    my mother on the other hand, who is 37 suddenly had a headache after li played a tone but she could not hear it. they got very annoying to me though.

  212. Anonymous Says:

    I’m 13, and I could hear them all. The mosquito ringtone what really loud to me, but the 18k one was pretty quiet. I thought that was pretty cool.

  213. Matthew D Says:

    Im 15 and i can hear all the tones…i had trouble so i found out if u point ur ear towards the speaker u can hear it better…..the last 1 took awhile but i turned my speakers full blast and then i heard it perfect!!!

  214. alex Says:

    can we get the tones in mid file format ? : (

    Hi i can hear the mosquito but i had an strange sound in my ears it hurts
    im 36

  216. Chris Says:

    25 y/o male. I can hear them all but they give me a headache and give me nausea. I’ve listened to them twice on two seperate occasions and it happened both times. The last time I listened with my 9 year old cousin and he could hear it from quite a long distance whereas I could only hear closer to the computer. Maybe the symptoms have to do with the volume being fairly loud but the perceived volume seeming really low.

  217. Lola Says:

    i am 13 yrs old and can hear them all perfectly, but my friend who is the same age as me cant hear the mosquito one (someone was testing it at school) and most people could hear it) and by younger brother could hear them all but not the 17959 Hz pure sine wave one. …..

  218. Mea Says:

    I’m 40, could hear all of them and they didn’t hurt. This surprised me as I worked with a rock band for many years and figured I wouldn’t be able to hear much.

  219. Mark Says:

    I’m 45. When I retired from the military six yeras ago I was told I had some high frequency hearing loss. Yet, I heard all the ringtones including the “mosquito”, even with the volume turned down. Guess I’m either young at heart or this is an awesome urban legend designed to fake out the kiddies in school.

  221. Ariel Says:

    I remember my mom calling me into the kitchen one day so she could play the Mosquito tone for me. She and my dad couldn’t hear it, but both of my brothers and I could hear it perfectly. I can hear all of them, though I have to admit they do get progressively harder to hear. The Mosquito one sounds low now that I’ve heard the other ones. It’s interesting, I thought the Mosquito was too high at first, but now that I’ve heard the others it doesn’t bug me as much.

  222. Ariel Says:

    I just realized I didn’t give my age. 16, by the way. And I apologize for the double post.

  223. JT Says:

    I’m 17 and I can hear all of them, but most of my friends cannot.

    this is insane guys me and my sister cold here it but both of my parents couln’t this is sssssoooooo kkkkooooooolll!!!!!!!!!!!!!!!

  225. Chelsea Says:

    I’m 17 and I could hear all of them, but the 18 hZ was almost inaudible… almost.
    I have an awful headache now from repeating them haha.

  226. Sarah Says:

    I heard everything. My ears are really sore! >.

  227. Jackie Says:

    Im 16 and could hear all of them. I thought I couldn’t hear the 18hZ one, so I played it several times….after about 5 times of playing it I could finally hear it and my head is hurting very bad….>.

  228. John Says:

    very loud, my dad cant hear it though :)

  229. Cocoa Says:

    We (my sister and I) could hear up to 20KHz. She’s 12 and I’m 15. My 46- and 44-year old parents couldn’t hear the ringtones. The former heard up to 13KHz, the latter 15KHz. We could hear up to 19 downstairs, but my parents could hear up to 12 KHz downstairs.

  230. Eddie Says:

    Ha! awsome… how do i get this on my phone?

  231. Alec Says:

    Depends on your phone Eddie. For a lot of phones you can just download the ringtone if you have a data cable. I do it all the time with my Nokia, RIM, and Microsoft Smartphone phones.

  232. Margaret Says:

    I tried out the NCH tone generator. I could hear everything up to 20,000Hz. Yay for being average? The mosquito tone is REALLY loud to me. However, my dad couldn’t hear it. He claims to be able to hear the sound a TV emits when it’s on though, which is a bit odd (and the mosquito is like that times 1000).

  233. Melissa Says:

    I’m .., so what? I could hear them all! :)

  234. Tracy Says:

    I can definately hear them and I am 40 and a teacher. I can hear the phones in class if there is not a lot of noise from the AC, student movement, talking etc. I am a science teacher, so I am going to develop a lab activity for this. Other teachers in my school cannot hear these tones.

    I will say the phone speaker and computer speaker makes a huge difference in whether I can hear the sounds. We tested the sounds on several phones and computers and I could hear all with good speakers, students could hear all on any quality speaker.

    Some tones are definately more annoying than others.

  235. REBEKAH JOHNSON Says:

    I COULD HEAR EVERY ON MY MOM COULD NOT AND NEATHER COULD MY DADDY THERE IN THERE 30S BUT THEY DID SAY THAT THERE EARS WERE RINGING AFTER IT MADE ME FILL LIKE MY EARS WOULD BLEED IT SOUNDED TERRIBLE WELL I NOW HAVE THE RING TONE AND NONE OF MY TEACHERS COULD HEAR IT SCORE!*!*!*!!* THINKS FOR THE PREVIEW

  237. Aaron Says:

    Well im 14 years old and I can hear all the tones just fine and all my life I have kept my music loud whether in my ear buds or stereo speakers Just thought I share that what I just dont understand is why we are buying these tones when vibrate works just as good heck thats what I use in class and I can feel when I have a txt or call coming in well anyways keep up the good work! (:
    Its no suprise that a 9 year old has a phone my neighbor’s son’s have phones and one is like around 9 years old and his brother is like 5 no joke maybe it because there dad works for Cingular

  238. Heather Says:

    I’m 19, could hear all except the last one. My head feels weird now though…

  239. Tara Says:

    I could hear the 16Hz faintly on my crappy laptop speakers, and the 15 and the mosquito one were quite loud and irritating. I’m about to turn 30. The 18Hz one sure agitates my cats though. I played it and one cat, which was sound asleep, freaked out. The other one came running from the other room and paces whenever I play it.

  240. ally Says:

    I’m a 46 year old teacher and I can’t hear any of them - I think working with crowds of children on a daily basis (playground and corridor decibels) pretty well wipes out your hearing..

  241. Robert Says:

    I am 45. I can hear all but the 16000. May be my laptop speaker limitations at that certain freq.

  242. Eddie Says:

    I can hear all of them - and working in a room where there’s a lot of fan noise from computers, it’s usua
