http://www.ultrasonic-ringtones.com I only heard to 12Khz (And just barely heard 12) I wonder if soundcards are able to reproduce a pitch that high correctly!
The only one I couldn't hear was 22.4kHz, I think it just depends on the quality of the sound card and speakers though.
Me too My poor doggy went nuts at 14 and left the room and hid under under the bed at 16! hahhaa poor doggy....
I can hear CLEARLY the 21.1kHz sound, but NO the 22.4kHz sound, so I guess the problem is on my sound card because the frequency response of my headphones is: 14Hz ... 26000 Hz
We actually did a proper experiment in a proper studio at uni last year. Because your hearing starts to deteriorate at the age of around 16 older people are less likely to pickup higher frequency sounds. Someone decided to play some frequency at the maximum volume so half of us run out of the studio with a headache and older people stayed because they could not hear anything. By the way, speaker frequency response is not always accurate. It depends how they measure it.
i was able to hear the 21.2!!! But now i feel like i kinda got a headache cause i played it 6 times to see if i actually heard it....im positive i did....Im 32 years old...I must have supersonic hearing...haha I hate when people have the pest control things that are super high pitch always bugs me
Hearing test results You are a liar You claimed to be able to hear a tone that contained absolutely no sound! I was able to hear 21.1 btw
I got to. 15.8kHz. I'm gonna try it on the other computers card but I don't think I can hear past it.
