NMMB said:I can hear it no problem (even with the volume on my computer turned WAY down) though I have two things that probably make this un-surprising:
1- I am less than a decade out of being a teen ...
2- I have very sensitive ears (I hear a lot of sounds that other people can't hear... and yes, they are real sounds... well, most of the time )
I assume that the reason for this has to do with deterioration of our ears as we age... any Dr.s, Biologists, etc want to give us more details?

phishkabob said:Very interesting. I am a doctoral audiology (hearing & balance) student and one of my professors was interviewed for a follow-up story on this topic/article. The deterioration of very high frequency sensitivity is not always inevitable. We are born with the ability to hear to ~20,000 Hz. With the assault of environmental (loud sounds, ototoxic medications, etc.) and biologic (predisposition to noise-induced hearing loss, renal disease, diabetes, etc.) factors, our hearing typically deteriorates with age. This age-related hearing loss is called presbycusis. Presbycusis starts at the basal end of the cochlea and moves in an apical direction. This means we slowly start losing the ability to hear high frequency (perceived as pitch) sounds, starting with the highest human-perceivable pitches first. There is debate within the audiological community related to the course, exact cause, and inevitability of presbycusis.
