| Abstract: | The foamglass for sound absorption is an inorganic porous material,which is good for fireproofing and water resistance.Some characters of the material are introduced,and the influences of the density,board thickness,air space from back regid surface,and moisture on sound absorbing according to the sound absorbing coefficients measured are analyzed.The method to improve its properties for sound absorption is used by perforating the board and leaving slot on the edge. |
