25th International Congress on Noise Control Engineering (Inter-Noise 96) - Noise control: The Next 25 Years, Liverpool, Birleşik Krallık, 30 Temmuz - 02 Ağustos 1996, ss.939-941
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.
