The analysis of free sound field in the anechoic room

Cai Yang-sheng

Abstract

In this paper,the building requisition of the anechoic room is introduced and the free sound field is emphasized.Based on the analysis result,it is proved that not all the sound absorbance coefficients of wall materials are 0.99 synchronously.The way obtaining the max range of the free sound field in the anechoic room which is confined with dimension is presented.
