為管理噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)和防備噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)性耳1聾供給(gei)法(fa)則和技(ji)能確保(bao)。我國(guo)在這方面極為重要(yao)，先(xian)后制定了《中華人民共和國(guo)環(huan)(huan)境(jing)噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)污染防治法(fa)令(ling)》、《工(gong)業(ye)、企業(ye)噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)衛生規范(fan)》和《城市區域環(huan)(huan)境(jing)噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)規范(fan)》等。噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)源(yuan)操控：操控噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)強度，改進作業(ye)和生活環(huan)(huan)境(jing)，降噪(zao)(zao)(zao)(zao)(zao)設備多少錢，是防治噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)損害底子、必定作用、活躍的辦(ban)法(fa)。環(huan)(huan)保(bao)組織和噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)源(yuan)單位應對環(huan)(huan)境(jing)和車間的噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)進行定時監瀏，消音降噪(zao)(zao)(zao)(zao)(zao)設備廠家，將噪(zao)(zao)(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)強度操控在國(guo)家規范(fan)所答應的規模之內。

消(xiao)聲(sheng)(sheng)(sheng)：消(xiao)聲(sheng)(sheng)(sheng)主要用(yong)于降低(di)空(kong)(kong)氣(qi)動力噪聲(sheng)(sheng)(sheng)，如空(kong)(kong)調通風噪聲(sheng)(sheng)(sheng)。允許(xu)氣(qi)流通過，又可(ke)(ke)減(jian)少噪聲(sheng)(sheng)(sheng)傳(chuan)播的裝置，通常稱消(xiao)聲(sheng)(sheng)(sheng)器。優良的消(xiao)聲(sheng)(sheng)(sheng)器應具(ju)備下述性(xing)能：消(xiao)聲(sheng)(sheng)(sheng)能量大——噪聲(sheng)(sheng)(sheng)衰減(jian)明顯；空(kong)(kong)氣(qi)動力性(xing)能好——力損失小；結構性(xing)能優——抗(kang)腐蝕性(xing)、堅固耐用(yong)、體積小。按照消(xiao)聲(sheng)(sheng)(sheng)原(yuan)理可(ke)(ke)將消(xiao)聲(sheng)(sheng)(sheng)器區分為(wei)阻(zu)性(xing)消(xiao)聲(sheng)(sheng)(sheng)器、抗(kang)性(xing)消(xiao)聲(sheng)(sheng)(sheng)器、阻(zu)抗(kang)復合消(xiao)聲(sheng)(sheng)(sheng)器、小孔(kong)和多孔(kong)擴(kuo)散消(xiao)聲(sheng)(sheng)(sheng)器等。
