摘　　要：城市、矿山民用锅炉房噪声治理,通常在送风巷进口、引风机出口加消声器,或为送引风机各自设计声箱,前者降噪量有限,后者治理费用高,为降低降噪费用,便於风机的日常维护和保养。作者为太安军分区第三干休所研制、设计了金属百叶式消声器,达到了预期目的。Noise control of civil boiler ventilator room usually was accomplished by dissipative muffer or sound-proofing lagging. The former fixed on the entrance of ventilator or outfall of draught fan was limited in effect, the latter cost too much. In order to drive costs down and be easy of maintenace, the author designed a bach shutter type dissipative muffer for a certain military unit. It achives the desired results
