<p> 車門隔音，先是用止振板粘貼在車門鈑金上，日系車可以在車門鈑金上做內(nèi)外2層，一些美德系車只能做一層，止振以后，在車門內(nèi)飾板上加上吸音棉，這樣止振和吸音都做到了。 </p> <p> 車地板和尾箱，翼子板也是和車門同樣的做法，不同的是各個(gè)部位才能采用不同的吸音材料。在地板位置，有些車主還會添加低頻王，專門的一種消除低頻噪音的材料。 </p> <p> 引擎蓋，除了止振以外，需要加一層隔熱隔音棉，主要是阻斷發(fā)動機(jī)的噪音和熱量的傳遞。全車隔音，**難做的就是發(fā)動機(jī)噪音，單做引擎蓋好U型槽還是很難起到明顯噪音的。消除發(fā)動機(jī)噪音，**理想的做法是做防火墻，但是做防火墻具有很高的風(fēng)險(xiǎn)，防火墻位置線路密集，既消耗工時(shí)，也存在高風(fēng)險(xiǎn)，在外面的隔音店一般都是不做防火墻的。

style="text-indent:25px">汽車隔音產(chǎn)品源于20世紀(jì)80年代末由美國一群汽車音響發(fā)燒友為了能夠更好的享受到汽車音響所帶來的樂趣而開發(fā)的，這些產(chǎn)品既是可以降低行駛過程中車內(nèi)的噪音，又可以提升汽車音響的音壓和音色。所以說汽車隔音原本是為真正熱愛汽車的享樂主義者而創(chuàng)立，目的是讓更多車主的生活得到完美的升華享受更美妙的駕駛樂趣。如果在汽車音響改裝之后不注意隔音，那么車主的享受可能會給路人帶來很大的困擾。具體來講，系統(tǒng)的隔音工程一般經(jīng)過減震、降噪、密封三個(gè)步驟完成。</p><p> 汽車隔音是根據(jù)車輛的性能、相應(yīng)的路況、使用的條件，對汽車產(chǎn)生的發(fā)動機(jī)噪聲、輪胎與路面產(chǎn)生振動的共鳴聲、車廂內(nèi)組件因間隙或老化受擠壓力產(chǎn)生的摩擦聲等作細(xì)致處理，以提高汽車乘坐的舒適性。 </p> <p> <p> 工作原理第一種是從發(fā)音源處進(jìn)行治理。如發(fā)動機(jī)大修，車體鈑金矯正，排氣管改裝等等，此方案的工程耗資巨大，時(shí)間較長，對維修技術(shù)的要求很高，處理不好易產(chǎn)生功能缺失和二次噪聲。 </p> <p> 第二種是在噪聲的傳播途徑上進(jìn)行隔除。主要是運(yùn)用專業(yè)聲學(xué)產(chǎn)品進(jìn)行車體密封、車體減振及車內(nèi)吸音，它不改變車體結(jié)構(gòu)、動力系統(tǒng)、車內(nèi)電路及管線，既安全又穩(wěn)妥，為大多數(shù)車主所接受，為此通常所說的隔音是后一種。 </p> <p> <br /> </p> </p><div

汽車隔音方法就是用某種隔音材料將聲源與周圍環(huán)境隔離，使其輻射的噪聲不能直接傳播到周圍區(qū)域，從而達(dá)到控制噪音的目的，隔音的要素取決于隔音材料的厚度和密度，由于車內(nèi)空間有限，車內(nèi)隔音材料主要采用高密度材料，才會有好的隔音效果。 </p> <p> 汽車因車身皆為鋼板架構(gòu)組裝或它種材質(zhì)組裝成一密閉空間、即車廂，而每一種車種，又因原廠設(shè)計(jì)理念不同，如引擎之設(shè)計(jì)、避震系統(tǒng)、進(jìn)排氣方式、車門、車體之緊密度……等，或靜止、或不同路面行進(jìn)狀態(tài)下產(chǎn)生不等值之噪音，經(jīng)鋼板、車體之共掁共嗚、聲音放大、過大之噪音令人不舒服、或耳鳴、或容易疲勞、或干擾到原本悅耳的音響效果……等，因此即須作汽車之隔音處理，所以，以原車之原廠設(shè)計(jì)組裝條件，加上各種消震、隔音、吸音材料，將車廂內(nèi)之不必要的環(huán)境噪音，排除到**小狀態(tài)，即為汽車隔音。廣東質(zhì)量汽車隔音哪家公司好</p><p
