管道(dao)隔(ge)振(zhen)處理(li)與泵組連(lian)接(jie)的管道(dao)增加(更換)橡膠(jiao)軟(ruan)連(lian)接(jie)，三亞降(jiang)(jiang)噪工程，一(yi)般軟(ruan)連(lian)接(jie)長度較短，彈性較差，樓頂(ding)降(jiang)(jiang)噪工程方案，致使整(zheng)體隔(ge)振(zhen)效果不理(li)想，更換后隔(ge)振(zhen)效果將明(ming)顯增加。軟(ruan)連(lian)宜接(jie)選用隔(ge)振(zhen)性能較好，長度較長且耐腐(fu)蝕的隔(ge)振(zhen)產品。管道(dao)支(zhi)架(jia)(jia)做減(jian)振(zhen)處理(li)一(yi)般的管道(dao)支(zhi)架(jia)(jia)與地面的連(lian)接(jie)均為硬(ying)鏈接(jie)，導致管道(dao)的振(zhen)動(dong)傳遞到(dao)建筑(zhu)結(jie)構(gou)，在支(zhi)架(jia)(jia)下面做好減(jian)振(zhen)處理(li)，能較好的阻止振(zhen)動(dong)能量(liang)向建筑(zhu)結(jie)構(gou)的傳播。

隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)設(she)計應注意的(de)問(wen)題1。隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)主要(yao)用于(yu)降低(di)直達聲(sheng)(sheng)(sheng)(sheng)對于(yu)輻射(she)高頻(pin)噪聲(sheng)(sheng)(sheng)(sheng)的(de)小型噪聲(sheng)(sheng)(sheng)(sheng)源，用半封閉的(de)隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)遮擋噪聲(sheng)(sheng)(sheng)(sheng)可以收到比(bi)較明顯的(de)降噪效果。2。在室內設(she)置隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)必(bi)須考慮(lv)室內的(de)吸聲(sheng)(sheng)(sheng)(sheng)處理(li)研究表(biao)明，當室內壁面(mian)(mian)、天花板以及隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)表(biao)面(mian)(mian)的(de)吸聲(sheng)(sheng)(sheng)(sheng)系(xi)數(shu)趨于(yu)零(ling)時，室內形成混響(xiang)聲(sheng)(sheng)(sheng)(sheng)揚，隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)的(de)降噪量(liang)(liang)為零(ling)。因此，隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)一側或(huo)兩側宜作(zuo)吸聲(sheng)(sheng)(sheng)(sheng)處理(li)。3。為了(le)形成有效的(de)“聲(sheng)(sheng)(sheng)(sheng)影(ying)區”，空調消音(yin)降噪工程，隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)的(de)隔(ge)聲(sheng)(sheng)(sheng)(sheng)量(liang)(liang)要(yao)比(bi)聲(sheng)(sheng)(sheng)(sheng)影(ying)區所需的(de)聲(sheng)(sheng)(sheng)(sheng)級(ji)衰(shuai)減(jian)量(liang)(liang)大10db，如要(yao)求15db的(de)聲(sheng)(sheng)(sheng)(sheng)級(ji)衰(shuai)減(jian)量(liang)(liang)，隔(ge)聲(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)(ping)本身要(yao)具有25db以上的(de)隔(ge)聲(sheng)(sheng)(sheng)(sheng)量(liang)(liang)，才能(neng)排除(chu)透(tou)射(she)聲(sheng)(sheng)(sheng)(sheng)的(de)影(ying)響(xiang)。
