In Reply to: It's old news (2005) - but I live in the woods... Tests confirm hearing above 22 kHz. posted by carcass93 on August 31, 2009 at 15:07:58:
But try 3 or 4KHz sine wave at 88dB and you'll be clamping your fingers in you ears.
Keep in mind the perspective here, there is a big difference between near excruciating and "just detectable" against a silent background.
It is so because you can detect 3-4KHz at near zero dB SPL, so here for a few to detect 24KHz at +88dB required 700,000,000,000 times louder /more acoustic power than at 3-4KHz would..
Your hearing at 24KHz is WAY down in sensitivity relative to 3-4 KHz, at the opposite end, the threshold of hearing for signals around 15Hz is also around 88dB if i recall.
Best,
Tom
