  水泵房的(de)(de)噪(zao)(zao)聲(sheng)主(zhu)(zhu)要(yao)由(you)制冷機組(zu)(zu)、電動機、風機等組(zu)(zu)成，其(qi)噪(zao)(zao)聲(sheng)主(zhu)(zhu)要(yao)為(wei)中低頻噪(zao)(zao)聲(sheng)，中低頻噪(zao)(zao)聲(sheng)的(de)(de)特點就是(shi)(shi)繞射(she)能(neng)力強，透射(she)能(neng)力強，吸聲(sheng)困難，是(shi)(shi)噪(zao)(zao)聲(sheng)治理中最棘手的(de)(de)問(wen)題，機房內聲(sheng)能(neng)量密度(du)過大，從而加重了透射(she)噪(zao)(zao)聲(sheng)的(de)(de)污染程(cheng)度(du)。

  而且水泵(beng)房的(de)振動(dong)(dong)相當(dang)劇烈，振動(dong)(dong)通(tong)過(guo)結構基礎傳(chuan)(chuan)遞(di)到樓上，再輻射(she)噪聲，形成固體傳(chuan)(chuan)聲。吊(diao)頂采用剛性(xing)連(lian)(lian)接(jie)，不(bu)能起(qi)到減(jian)振作用，反而加速了振動(dong)(dong)的(de)傳(chuan)(chuan)播，管道的(de)振動(dong)(dong)通(tong)過(guo)剛性(xing)連(lian)(lian)接(jie)直接(jie)傳(chuan)(chuan)遞(di)到基礎，影響居(ju)民的(de)正常生(sheng)活和休息，需進行噪聲治理和減(jian)振處理。

  水(shui)(shui)泵房噪(zao)(zao)(zao)音治理的關鍵問題首先是(shi)水(shui)(shui)泵的噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)，這是(shi)一種(zhong)機(ji)械噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)和(he)流(liu)體噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)，主要通過基礎傳播，軟連接和(he)減(jian)振是(shi)治理的關鍵點，而減(jian)振系統(tong)的設(she)計(ji)又是(shi)重(zhong)中之重(zhong)。第(di)二(er)個(ge)關鍵問題是(shi)室內聲(sheng)(sheng)(sheng)能(neng)(neng)量，過高的聲(sheng)(sheng)(sheng)能(neng)(neng)量會增(zeng)加透射的聲(sheng)(sheng)(sheng)能(neng)(neng)量，結構吸(xi)(xi)聲(sheng)(sheng)(sheng)是(shi)水(shui)(shui)泵房室內吸(xi)(xi)聲(sheng)(sheng)(sheng)比較有(you)效的方式(shi)。

  抓住水泵房噪音治(zhi)理的(de)關鍵問(wen)題(ti)，治(zhi)理的(de)難度也(ye)就減(jian)少(shao)了，最重(zhong)要的(de)是(shi)設計合(he)理的(de)減(jian)振系統和吸聲結構。
