Abstract

A number of plates made of perlite were prepared. Plates were moisturized at different levels. Their absorption coefficients were measured by the ''two-microphone impedance tube'' method. Experimental results were introduced and the moisture effects on acoustical properties of plates made of perlite were discussed.
