Re: Spaces with unusual acoustics, long reverb, echo's etc.

["Lou Judson" inaudio]

Recently read online about the larg reflectors built in the coast of  
England between the world wars to detect distant aircraft sounds,  
before the development of RADAR, and when planes were stilll rather  
slow to acoustics could give 15 minutes warnng of attacks...

Here's one link, google can find more. Would be interesting  
expriments in recording them...

Generally highly reverberant spaces are man-made & result from large
flat reflective surfaces without much diffusion, or enclosed spaces
