Abstract

A sound-damping acoustic device comprises a sheet-material member (14) which can be set, by sound, into oscillatory motion transversely to its geometrical extension, and which forms at least a part of the defining walls of a chamber (16). The member (14) is substantially free-swinging, and the chamber (16) is at least substantially acoustically closed. The device also comprises means for damping displacement of the member transversely to said geometrical extension in proportion to changes in the rate of displacement.
