吸声减噪吸声减噪absorption,noisereductionby利用吸声装置(吸声饰面、空间吸声体等)吸收室内的混响声能以降低噪声的方法。吸声减噪适用于原有吸声较少、混响声较强的建筑物的降噪处理。吸声减噪能达到的A声级降噪量,在一般车间厂房为3~8分贝(dB)左右;几何形状特殊(声聚焦)、混响极严重的建筑物,降噪量可达12分贝左右。吸声装置的声学设计主要根据噪声源的频谱特性。吸声减噪的处理方式通常有以下几种:①房间面积较小的吸声减噪,宜对天花板、墙面同时作吸声处理。②车间面积较大时,尤其是扁平状车间,一般只作平顶吸声处理。③声源集中在车间局部区域而噪声影响整个车间时,应在声源所在区域的天花板及墙面作局部吸声处理,且应同时设置隔声屏障。④吸声降噪效果并不随吸声处理面积成正比增加,空间吸声体面积宜取房间平顶面积的40%左右或室内总表面积的15%左右。空间吸声体的悬挂高度宜低些,离声源近些。吸声减噪设计应同时满足防火、防潮、防尘等工艺与安全卫生的要求,同时还应兼顾通风、采光等。中国上海黄浦体育馆的吸声减噪吊顶
