Convention Paper

Radiation of Sound by a Baffled DML-Panel Near a Porous Layer

Authors: Prokofieva, Elena

AES Convention 115 · Paper 5884 · October 2003

Abstract

Theoretical analysis of the problem of an elastic rectangular vibrating panel placed into a baffle in the vicinity of a porous layer has been conducted. Numerical results were obtained from a special computer program written in Matlab 6.0. It has been found that the presence of the porous layer considerably alters sound emission by the panel. The effect of the porous layer characteristics as well as the air gap width between the vibrating panel and the porous layer on the acoustic pressure and surface velocity was investigated.
