压缩机房的噪声很高，约９０ｄＢＡ。工作中要藉助机器噪声来判断其运转是否正常，在这种情况下，一般宜采用吸声降噪的方法。本文主要介绍一种新型吸声材料──纸蜂窝吸声体在压缩机房中降噪的应用，包括机房噪声的测量，吸收材料的布置，降噪量的预计和实测与计算降噪量的比较 Compressor room noise is high, about 90dBA. In the course of work, it is necessary to use machine noise to judge whether its operation is normal or not. Under such circumstances, the method of sound absorption and noise reduction should generally be adopted. This paper introduces a new type of sound-absorbing material ─ ─ paper honeycomb sound absorber noise reduction in the compressor room applications, including the measurement of noise in the engine room, the layout of absorbent material, the expected amount of noise reduction and measured noise reduction compared with the calculation
