I was once in a large windowless basement room, the entrance to which
was a corridor with a closed fire door at its end. The room was mostly
empty, and all walls were concrete or cement block. When the lights went
out, I had no difficulty locating the corridor by clapping my hands and
listening. I had supposed that the absence of echo from the corridor
would guide me, but I was wrong. The sound traveling down the corridor
and returning created a distinct delayed echo that was a good guide.

I would have measured the spectrum of his click. Unfortunately he died
