-Alex- Posted February 12, 2008 Share Posted February 12, 2008 (edited) Just read an article about the Kids' Commisioner trying to ban 'Mosquito' devices as they discriminate against youths. Basically, they are installed outside shops etc to stop gangs of youths hanging around outside. It's a high frequency noise that only under 25's can hear. But, my question to you is: what is the highest frequency you can hear? 8khz Everyone Play The 8khz Tone 10khz 60 & Younger Play The 10khz Tone 12khz 50 & Younger Play The 12khz Tone 14.1khz 49 & Younger Play The 14.1khz Tone 14.9khz 39 & Younger Play The 14.9khz Tone 15.8khz 30 & Younger Play The 15.8khz Tone 16.7khz < 24 Play The 16.7khz Tone 17.7khz < 24 Play The 17.7khz Tone 18.8khz < 24 Play The 18.8khz Tone 19.8khz < 24 Play The 19.8khz Tone 21.1khz < 24 Play The 21.1khz Tone 22.4khz < 24 Play The 22.4khz Tone Myself, I can hear up to 17.7Khz Edited February 12, 2008 by -Alex- Link to comment Share on other sites More sharing options...

Slugsie Posted February 12, 2008 Share Posted February 12, 2008 I can hear the 19.8khz sound, and I am 37. It's odd, because late last year I checked my hearing out, and I could hear even higher frequencies, so I guess my hearing is going down hill rapidly.

Malbojia Posted February 12, 2008 Share Posted February 12, 2008 21.1khz, My ears felt the sharpness of the tone for the following 5 minutes after. The lowest I can hear is at 100hz. Drop it to down to a single increment dissapears from my ear drum. Link to comment Share on other sites More sharing options...
spacer Posted February 12, 2008 Share Posted February 12, 2008 You forgot the one that's twice as high as the 22.4 entry: "Wife/Girlfriend when angry" I choose ^that ^ one. Link to comment Share on other sites More sharing options...
Black Hawk Posted February 12, 2008 Share Posted February 12, 2008 I'm can only hear up to 15.8kHz and I'm 22. My hearing is probably sub-normal since I most likely raped my ears with my car audio system. Link to comment Share on other sites More sharing options...
Keito Posted February 12, 2008 Share Posted February 12, 2008 I can't hear above 21.1kHz - also need to pump up the volume to hear the 21.1kHz one I'm 19 btw Link to comment Share on other sites More sharing options...

chezy666 Posted February 12, 2008 Share Posted February 12, 2008 But wont this depend on whether our speakers can produce the sound. Link to comment Share on other sites More sharing options...
-Alex- Posted February 12, 2008 Author Share Posted February 12, 2008 From the website: All newer computers built within the last 5 years will have a sound system that is capable of playing these tones. However, older or poor quality speakers are a different story. :) Link to comment Share on other sites More sharing options...
dysmatik Posted February 12, 2008 Share Posted February 12, 2008 19.8khz and I'm surprised its that good considering all the raves I used to go to back-in-the-day. Link to comment Share on other sites More sharing options...
Napalm Frog Posted February 12, 2008 Share Posted February 12, 2008 But wont this depend on whether our speakers can produce the sound. I think so. The frequency response on my set is under 20 kHz, and oddly enough the 19.8 kHz is the last I can hear. I'm almost 22, if that makes a difference. Though, at such a high frequency, it really is more of a "feel" than a hear, my head hurts now, lol. Link to comment Share on other sites More sharing options...
chezy666 Posted February 12, 2008 Share Posted February 12, 2008 Upto 21.1khz without any problems, at 22.4KHz I cant hear anything, but winamp's oscilloscope does'nt register anything either. Link to comment Share on other sites More sharing options...
Pretend Posted February 12, 2008 Share Posted February 12, 2008 21.1kHz :) Link to comment Share on other sites More sharing options...
Hum Posted February 12, 2008 Share Posted February 12, 2008 I can hear 21.1khz :D But I'm not sure this is a fair test -- it would depend on the frequency range your amp/speakers or headphones can reproduce. Link to comment Share on other sites More sharing options...
santiagof4 Posted February 12, 2008 Share Posted February 12, 2008 I can hear up to 21.1kHz... but the 22.4kHZ one... any oscilloscope I have (and a professional software) doesn't register anything. Link to comment Share on other sites More sharing options...
MightyJordan Posted February 12, 2008 Share Posted February 12, 2008 My ears must really be f***ed up! I'm only 16, but I can only hear up to 15.8! :o Link to comment Share on other sites More sharing options...
Hooya Posted February 12, 2008 Share Posted February 12, 2008 The ****ty speakers I'm on won't play the 19.8 one or higher. I know I can hear up there (even though I'm 26) because I'm always the guy in the room that knows the TV is on with no picture. That's usually a 20kHz pitch or so. There's also a really high pitch whine in my office (probably from the computer/monitor eMac) that could be drowning out some of the higher pitches. I'm a professional orchestral musician, so this is sure to go down for me soon (damn trumpets!). I wear earplugs for a lot of rehearsals though.

RDPaul Posted February 12, 2008 Share Posted February 12, 2008 I also can hear upto the 21.1, but not the 22.4, not sure if its my speakers, my ears or the file :s Link to comment Share on other sites More sharing options...
ramesees Posted February 12, 2008 Share Posted February 12, 2008 The 19.8 and 21.1 sound is a really deep droning on my speakers, compared to the rather pin like whining of the other noises. I couldnt hear the 22.4 one though. So assuming I heard the 19.8 and 21.1 sounds correctly, then I heard up to that, otherwise the highest I could hear "correctly" would be 18.8. I'm 26 btw and will be 27 in March Link to comment Share on other sites More sharing options...
Thrawn Posted February 12, 2008 Share Posted February 12, 2008 I don't know how good computar speakers are at reproducing pure tones at these frequencies, so I think those audio clips are really dubious. I happen to be in a physics lab, so I have a function generator and piezo speakers lying around. I can hear 22 KHz as a whisper, and nothing higher. I like the observation of the deep droning above. The speakers couldn't reproduce the sound, so I wonder how many people who are reporting higher frequencies are actually reporting just that. My speaker was set really loud... although I could bearly hear the 22 KHz, I think it gave me a headache... PS: This body is 21. Link to comment Share on other sites More sharing options...

Thrawn Posted February 12, 2008 Share Posted February 12, 2008 ****... 16.7khz is the first one i can hear.. im 23my hearing must be shot to ****! :( No no, it might just be your speakers. Link to comment Share on other sites More sharing options...
Pajter Posted February 12, 2008 Share Posted February 12, 2008 I could hear up 'till 21.1kHz Quite weird though, because I recently had a hearing test and my hearing was actually above the average person. (not on all frequencies) Might be that there's a lot of background noise here right now. I'm 20 in a few weeks. Link to comment Share on other sites More sharing options...
