Subject:    Mirrors and sound reflection
Text:       Mirrors reflect light.  Do they also reflect sound?

Response #:  1 of 1
Author:      John Hawley
Text:        Any acoustically smooth hard surface will reflect sound, so a 
glass mirror is a pretty good sound reflector but aluminized mylar is not.  
What constitutes an acoustically smooth and hard surface changes with the 
frequency of the sound.
