34 yrs old, & can hear it clearly! So annoyingly funny!! PLEASE STATE YOUR AGE, COUNTRY, AND ANSWER "CAN YOU HEAR IT?" --> 32 years old and I can hear it, on and IMAC computer speakers, I played it while there were 3 more people in the room, 2 over 50 did not hear it, 1 who is 40 heard it, however when i played the sound off my smartphone speakers all heard the buzz.
Heard by an almost 35 yr. old female - can't hear anything past 19.5khz.
PLEASE SIGN BY TYPING FOUR TIMES ~ I'm 32 from Scotland in the UK and I can hear it quite loudly. It seems to die away rather than just stop and I found myself pulling a face whilst listening as it was soooooooooooo annoying! They've just fitted one of these in my neighbourhood to try and deter young kids hanging around. Don't know what the outcome will be.
I'm 12, in Arizona, and I can hear it. Very loud. My grandma is 63, and she can even hear it.
I´m 33, from Brazil, and didn´t hear a thing. And I know people above 40 who did... damn it. Zumbitone 07:56, 23 June 2006 (UTC)
I just turned 20 and am from the US. I can hear the tone, but not as loud as my 15 year old brother describes it. Just be wary that some websites have the sample in mp3 mode which can downgrade the quality and would be at a lower frequency than 17KHz which allows older people to hear it. Try finding a sample in wav format. Here's the one I used: http://www.jetcityorange.com/toys/17KHz.wav. Ignore the popping noise in the file. [[User:] 05:44, 30 June 2006 (UTC)
17 in the US. I can definitely hear it, and it sure does HURT!
30 in the USA. I can definitely hear it and it hurts my ears~ Nuts to that, at least I am not as old as I thought I was~ =P AMG
38, United States: Ouch I can definitely hear it. My ears are still ringing even after I turned it off. The ringing in my head that I have now reminds me of the high pitch noise I hear after I have spent a night at the bars listening to loud music.
24, US: YES I can definitely hear it. Sometimes I grow used to it and I can't hear it anymore. I am definitely using this on the neighbor's dog.
12, Toronto Canada : OMG this is frickn awesome!! though, u shud listen to a nother file which is 23 khz . I couldn't even hear that one just at the beginning and tats it
OMG.... I was sitting in school....I am in 12th grade and i am 18.....and at lunch people were talking about this noise that only kids can here. I asked to here it and it was so high pitched it reminded me of someone being torchered. lol it was great so i downloaded it and had fun. now 1/2 the school has it b/c we all blutooth it to eachother. Some teachers ( the younger ones ) can here it and some students cant. I think it is so kewl for someone to make stuff like this and that more should be made. I am from MISSOURI in the U.S.A.
