根據電梯(ti)噪(zao)聲(sheng)產(chan)生(sheng)特性及傳遞方(fang)式，電梯(ti)噪(zao)聲(sheng)源可歸類(lei)為以下兩大類(lei)：    

機房結構性傳聲：由電梯主機及機房控制柜發出，電梯機房內的主承重粱主墻與業主家內的主墻為一公共墻體或都是剛性結構連體，因此構成電梯噪聲主要傳播“聲橋”，電梯在高速運行及停車時的低頻振動及噪音通過聲橋傳入住戶室內。目前較為普遍的室內電梯噪聲污染案例類型，以頂層或次頂層的住戶受噪聲影響，其它層樓受影響不大，通過增設低頻阻尼復合減振裝置降低振動傳遞率把噪聲降低至使人舒適的聲環境以下。     

井道(dao)結構性傳(chuan)聲：電梯運(yun)行(xing)時，轎廂及(ji)對重(zhong)塊(kuai)主(zhu)導(dao)軌(gui)磨擦傳(chuan)遞至井道(dao)結構引起的噪聲問(wen)題。電梯主(zhu)道(dao)軌(gui)固定于門的兩側(ce)與墻(qiang)(qiang)體連(lian)接，轎廂導(dao)軌(gui)上滑行(xing)停(ting)止時的磨擦及(ji)振(zhen)動會通過固定導(dao)軌(gui)與墻(qiang)(qiang)體連(lian)成(cheng)“聲橋(qiao)”，傳(chuan)到(dao)住戶室內。
