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
