在生活中，管道用來承擔運輸各種液體、氣體的任務，其輻射的噪聲無論是室內還是室外，都對人們生活、工作產了較大影響，損傷人的聽力，管道噪聲主要來自於流體機械噪聲，與流體的壓力、速度和輸送流體的動力源有關，而管道輻射噪聲的強度又與管道的結構、材料的剛度、密度、管壁厚有關。
生活中產生噪聲最多的排水管道，產生的噪聲達70dB以上，工業管道噪聲甚至於高達100dB以上，對管道進行隔聲處理刻不容緩。
用OFF系列金屬隔聲氈包覆管道，可以有效減少管道噪聲輻射，一般的家用排水管道，直接用OFF系列金屬隔聲氈就能滿足隔聲要求;工業噪聲治理可在用OFF系列金屬隔聲氈之前，先用超棉、礦棉進行包覆，最後用鍍鋅板作為外殼護面板，這樣可增加高
頻和低頻的吸收，使其綜合隔聲效果更加優越。
In daily life, the most noise from drainage pipeline more than 70Db. Industrial pipeline noise is as high as 100 db above, so we need to conduitacoustic immediately.
In the daily life, Pipe used to undertake transport all kind of liquid, gas task, the radiation noise whether indoor or outdoor which influence our living, working and damage our hearing. Pipe noise mainly comes from the fluid mechanical noise, relevant to fluid pressure, speed and conveying fluid power supply.
With the cover of the OFF series metal acoustic felt which can effectively reduce pipeline noise radiation. In our common house drainage pipeline, we can direct use the OFF system metal acoustic felt to meet the acoustic requirements. For industrial noise management we can usefirst super cotton, cladding with mineral wool before use OFF series metal acoustic felt, and finally use galvanized sheet as a shell protection panel. Which it can increase the absorption of high frequency and low frequency; make its comprehensive sound insulation effect more superior.
