Human Sonar

[swestrup]

I once read a Science Fiction story in which the main character got around in lightless caves via echo location. He clicked rocks together and navigated by the sounds, like a bat. I thought it a bit far fetched at the time, but now it turns out that people can do that.

I knew a blind man long ago in Winnipeg who found his way around by how the buildings and such modified the ambient noise.

What book was that? It rings a bell.

It took me a few minutes to google it. It was "Dark Universe" by Daniel Galouye.

read that book years ago and the title eluded me until it came up on Asimov's forum a while back --IIRC, there was another group caleld 'zivvers' who would see infra-red.

Yup, and 'ziv infrared' was what I googled on to find the book info.

Nope, don't know it. I think I may have read a short story with a similar character - oh, wait, it was probably in a comic book. That's a pretty obvious super hero power.

He wrote another book that was essentially the same, but instead of discovering light, people discovered amazing psychci powers.
