Talk:Ultrasonic hearing

From Wikipedia, the free encyclopedia

Can anyone put in a reference on what it is like to hear sounds of such high frequencies? It's hard to imagine what it would be like.--RLent 22:07, 2 February 2007 (UTC)

"Deatherage[3] states that what humans experience as ultrasonic perception may have been a necessary precursor in the evolution of echolocation in marine mammals."

Ultrasound says the effect was first discovered by scuba divers hearing navy sonar, so the underwater aspect should be pointed out. — Omegatron 23:16, 27 April 2007 (UTC)

So who's the Deatherage guy? --Foma84 (talk) 09:49, 4 April 2008 (UTC)

I had an ultrasound done today on my thyroid, and the tech confirmed that I could tell when she was using it. The color scan seems to be the loudest / most obvious.

It’s difficult to describe, because I don’t have an adequate frame of reference. It’s not really “like” anything, although if I had to, I’d say it is something like that whine you hear just before a laser printer kicks out a piece of paper. It’s a high pitched but not unpleasant pulse, not like a mosquito, or like when the t.v. is doing the white noise thing. Just a soothing drone really.M-w-b (talk) 05:01, 25 January 2008 (UTC)
