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:
It is not a secret that children exhibit response out to 25kHz or so. The 20kHz limit is an average for young adults. And generally females
perform better than males.
Now check the paper's listers: 4 males, 11 females, aged 18-33. No surprises here.
"88 dB on average is actually quieter than I usually listen personally."
That 88dB is the limit for detection. Contrast that to ~0dB for a 3kHz tone or so. Expect the > 20kHz sound to be masked entirely by any musical signal
with a loudness North of, say, the final bars of Holst's Neptune.
I wouldn't want to be in a room with 20kHz at 88dB SPL ... but then, maybe I am a bug or a rat.
And then you wake up and realise that your classmates of old ... are running most of the TV shows.
