I'm 28 and My hearing age is 50! :|
maybe your headphones/speakers are brokenWell this is strange because I could only hear the 8000Hz(Everyone) and 19 000Hz (Under 20). I couldn't hear any of the other frequencies. I'm 28 :wtf:
Doesn't audio compression discard frequencies that you generally can't hear? I wouldnt trust the youtube video. Play an uncompressed WAV, or AIF file and I guarantee you will get better bresults.
