隔(ge)(ge)音(yin)材料的(de)(de)(de)安(an)(an)裝方法務必比較簡(jian)單，不(bu)然也沒辦(ban)法做到理想化的(de)(de)(de)隔(ge)(ge)音(yin)降(jiang)噪實(shi)(shi)際效果。技(ji)術(shu)專(zhuan)業的(de)(de)(de)聲學材料技(ji)術(shu)工(gong)(gong)程(cheng)(cheng)師都清(qing)晰(xi)，一種墻面假如在試驗(yan)(yan)室里檢驗(yan)(yan)能隔(ge)(ge)音(yin)降(jiang)噪X聲貝(bei)，在具體(ti)工(gong)(gong)程(cheng)(cheng)項(xiang)(xiang)目中(zhong)經常(chang)只有隔(ge)(ge)音(yin)降(jiang)噪X-2分(fen)貝(bei)，乃至隔(ge)(ge)音(yin)降(jiang)噪實(shi)(shi)際效果更低。導(dao)致具體(ti)工(gong)(gong)程(cheng)(cheng)項(xiang)(xiang)目中(zhong)墻體(ti)隔(ge)(ge)音(yin)值小于試驗(yan)(yan)室參考值關鍵有兩個緣故：包含具體(ti)工(gong)(gong)程(cheng)(cheng)項(xiang)(xiang)目中(zhong)的(de)(de)(de)側面傳播聲音(yin)難題，和具體(ti)工(gong)(gong)程(cheng)(cheng)項(xiang)(xiang)目中(zhong)板墻的(de)(de)(de)安(an)(an)裝品質比不(bu)上試驗(yan)(yan)室里專(zhuan)業人員的(de)(de)(de)安(an)(an)裝品質導(dao)致的(de)(de)(de)。

　　因而，隔(ge)音材料安(an)(an)裝(zhuang)務必(bi)簡易(yi)，不(bu)(bu)然當場的(de)安(an)(an)裝(zhuang)工(gong)作(zuo)人員毫(hao)無疑問(wen)會出現出錯，造(zao)(zao)成 墻面隔(ge)音性(xing)(xing)(xing)檢測值不(bu)(bu)上隔(ge)音性(xing)(xing)(xing)總體(ti)(ti)(ti)目(mu)標。例如，延展(zhan)性(xing)(xing)(xing)橫杠在(zai)國(guo)外(wai)以(yi)前(qian)應用較(jiao)多，它自身是一種非常好(hao)的(de)隔(ge)音性(xing)(xing)(xing)方式和商品，在(zai)試驗室內應用延展(zhan)性(xing)(xing)(xing)橫杠能夠 將(jiang)質(zhi)輕紙(zhi)面石膏板墻的(de)隔(ge)音降噪實(shi)際(ji)效果提升5-10聲貝，殊不(bu)(bu)知(zhi)在(zai)具體(ti)(ti)(ti)工(gong)程項目(mu)中，安(an)(an)裝(zhuang)工(gong)許多 情(qing)況下都不(bu)(bu)可以(yi)將(jiang)板才(cai)精(jing)確(que)地安(an)(an)裝(zhuang)在(zai)延展(zhan)性(xing)(xing)(xing)橫杠上，造(zao)(zao)成 墻面具體(ti)(ti)(ti)隔(ge)音降噪實(shi)際(ji)效果提升十分(fen)比(bi)較(jiao)有限。因而，英(ying)國(guo)早已慢慢放棄(qi)了這類墻體(ti)(ti)(ti)隔(ge)音技術性(xing)(xing)(xing)和方式。
