INTERFERENCE OF SCATTERED AND REFLECTED SOUND (ESSAY OF A THEORY OF BOTTOM REVERBERATION).

Abstract

The prolonged reverberation of underwater sound re-echoed from the ocean floor is interpreted as an interference phenomenon, due to the combined effect of scattering and reflection of sound waves at the bottom of the sea. So construed, it is the acoustic counterpart of a striking, though little known, optical phenomenon: the interference of light reflected from imperfect, dusty mirrors. All but forgotton today, these interference effects used to be known as Newton's diffusion rings, after their discoverer. (Author)
