一、高速公路主要噪聲源

高速收費站鐵(tie)路上的嗓(sang)聲最主要來(lai)原有三個

1、結構類(lei)型噪(zao)音(yin)污(wu)染(ran)：貨(huo)車輪胎與(yu)橋面滾動摩擦所產生的噪(zao)音(yin)污(wu)染(ran)

2、冷氣氛(fen)噪(zao)(zao)音(yin)分貝：車體與冷氣氛(fen)擠壓(ya)造成的噪(zao)(zao)音(yin)分貝

3、汽(qi)車燥音：鳴笛、剎(cha)車聲、開車燥音等

二、速(su)度鐵路(lu)降噪處(chu)理錯施(shi)

推(tui)廣(guang)聲(sheng)(sheng)(sheng)防(fang)御系(xi)統(tong)(tong)(tong)。因說(shuo)話聲(sheng)(sheng)(sheng)是(shi)球面鏡波(bo)，粘(zhan)附今后只可(ke)(ke)以遵(zun)循(xun)消(xiao)化和辦公(gong)隔(ge)斷的具體(ti)方(fang)法(fa)來展開(kai)調控(kong)。日(ri)前，能高(gao)于最(zui)適隔(ge)音消(xiao)除(chu)(chu)噪音的結果的調控(kong)情況報(bao)告，是(shi)為(wei)路途設置成全(quan)封閉(bi)室式(shi)(shi)吸隔(ge)聲(sheng)(sheng)(sheng)防(fang)御系(xi)統(tong)(tong)(tong)。因為(wei)充(chong)分考慮可(ke)(ke)玩性，在隔(ge)音消(xiao)除(chu)(chu)噪音與區(qu)域經濟財政投入相互間，應該(gai)找出1個(ge)穩(wen)定點，直臥式(shi)(shi)聲(sheng)(sheng)(sheng)防(fang)御系(xi)統(tong)(tong)(tong)都不錯(cuo)的情況報(bao)告，常見在地區(qu)客(ke)運低(di)頻噪音制理。直臥式(shi)(shi)聲(sheng)(sheng)(sheng)防(fang)御系(xi)統(tong)(tong)(tong)構造(zao)簡單(dan)，利于大批量集中采購，配置便宜。這面對防(fang)御系(xi)統(tong)(tong)(tong)型成的聲(sheng)(sheng)(sheng)影區(qu)位置內明感點，有順暢的守(shou)護意義。但(dan)這面對高(gao)層(ceng)領導建筑工(gong)程(cheng)建筑工(gong)程(cheng)，則的結果比較(jiao)比較(jiao)有限，最(zui)主要的靠(kao)其(qi)過(guo)遠的距(ju)離感必然衰減。
