摘要
利用工业废物（废纸浆、玉米轴等）制成复合层压板，并对该板的声学性能进行实验，实验结果表明，声频在1000～6000Hz降噪明显，该复合板可做为隔音材料．
The acoustical properties of the composite pressed-accumulate plate, which is made up of industrial and agricultural waste (waste paper pulp, corncob etc.) are tested. The results show that nosize reduction effect is obvious in range of acoustic frequency (1000~ 6000 Hz). The composite pressed-accumulate plate can be used to acoustic celotex material.
