Hearing test

[Fred Scuttle]

Tried with both my iPhone earphones and an older pair from a portable CD player: with both of them up to 12KHz was fine, 14KHz was very faint, and nothing beyond that. The iPhone ones are specced to go up to 20KHz, so I assume the problem lies somewhere between the speakers

I am having fun with the 14KHz made in to a mp3 loop running in the office.

Only 12khz. But then I do hear a high pitched hiss all the time that more than makes up for it. And I hear bumblebees in my bedroom at night.

Me too. Except I don't hear bumblebees at night. It's just the wife snoring!

My clientco PC has no sound card, but I've been meaning to listen to a reconstructed sound of a Neanderthal

(The wav file, if it hasn't been moved, is here.)

Neanderthals are believed to have preferred hunting in dense forest, where their lack of speed was less of a problem than out in the open, and I suspect they were excellent mimics and perhaps relied on imitating the grunts and squeels of hogs and wild boar etc to lure these close enough to spear.
