I can hear up to 19kHz well but i can only barely hear 20kHz and 21 kHz with full volume.
my head hurts now =.= i hate those high pitch things they have at some stores, and some cell phone chargers do it too. my mom can't hear it but it drives me crazy.
I can hear up to 17, but higher than that it's like the sound just stop. I figure I'd be able to slightly hear 18, as 17 was still pretty clear, but whatever.
I'm going to have o get Tom to listen to this, he's really sensitize to high pitched sounds (they trigger his migraines), and even complains when we walk into major hardware stores as they have bird scare contraptions. These things are little boxes, high up in the ceiling, that emits a constant buzzing sound set at a frequency most people can't hear. I could just barely hear it, and wouldn't notice it unless someone points it out, but to him it's like a jackhammer pounding on his eardrums.
Hmm... interesting. I can hear all but the last one.
The pups didn't like this test very much though! It was actually kind of cute watching them cock their heads from side to side trying to figure out where the heck that stupid tone was coming from.
I'm having a problem believing these audio clips are at a correct frequency.
Human frequency response, according to biometrics, goes from 20Hz to 20KHz. It does decrease with age, so it seems that most middle aged people can't make it past 14KHz. Another thing is that the vast majority of computer speakers doesn't respond past 18Khz. I'm holding a pair of Genelec digital speakers for professional use and their marked response frequency is 20KHz and they start to loose response efficiency at frequencies slightly over 18Khz. There are speakers that respond to more than the 20Khz, but they're normally professional grade audio monitors.
I tested the files for actual audio presence here at work, and the higher pitched ones do have audio in them, but at a very low volume. Unfortunately I don't have anything here to tell me the exact frequency of these clips. I am curious though.
Well, I downloaded a demo version of a spectrum analyzer. It seems all frequencies are pretty much accurate on the meter. Variation at a maximum of about 300Hz for peak level.
I can go up to 18KHz on my iMac built-in speakers, actually hearing the frequency buzz. I can't find the specs for these speakers, but I'd be surprised if they responded to more than that.
Most speakers are not balanced 20hz-20,000hz because people cannot hear it and it's nearly impossible to replicate that spectrum with just a single tweeter or woofer. Much less pack it all into a laptop speaker. Back in the day when I worked at a recording studio they had a mastering room in which the tower speakers had even response from 20-20k, they cost like $8,000.

i'm partly a musician too (played violin since 4th grade) so i wonder if that affects this at all.

Skella was like, wtf?
