摘　　要：吸声泡沫玻璃是一种无机多孔材料,它具有良好的防火和耐水性能。介绍了它的材料特性,根据测量的吸声系数分析了密度、板厚、空腔和吸湿对吸声的影响,并且采用板面钻孔和边缘留缝的方法提高其吸声性能。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.
