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(duì)汽車產(chǎn)生的發(fā)動(dòng)機(jī)噪聲、輪胎與路面產(chǎn)生振動(dòng)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(dòng)機(jī)大修，車體鈑金矯正，河源高級(jí)汽車隔音質(zhì)量放心可靠，排氣管改裝等等，此方案的工程耗資巨大，時(shí)間較長(zhǎng)，對(duì)維修技術(shù)的要求很高，河源高級(jí)汽車隔音質(zhì)量放心可靠，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(dòng)力系統(tǒng)、車內(nèi)電路及管線，河源高級(jí)汽車隔音質(zhì)量放心可靠，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> 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(huì)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(dòng)機(jī)的噪音和熱量的傳遞。全車隔音，**難做的就是發(fā)動(dòng)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(dòng)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。

</p> <p> 隔音 </p> <p> 隔音是用某種隔音材料將聲源與周圍環(huán)境隔開，使其隔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。 </p> <p> 減振 </p> <p> 減振就是在易產(chǎn)生振動(dòng)的區(qū)域安裝彈性材料或元件，隔絕或衰減振動(dòng)的傳播，從而實(shí)現(xiàn)減震降噪的目的。 </p> <p> 密封 </p> <p> 密封不僅能阻隔噪聲的傳播通道，避免氣流分離，還可擾亂周期性的尾流，從根本上降低風(fēng)噪。 </p> <p> <br /> </p><p> 噪音的產(chǎn)生，離不開三個(gè)因素：音源，傳播介質(zhì)，接收者（耳朵）。音源就是噪音產(chǎn)生的源頭，這個(gè)我們是沒辦法消除的，胎噪，風(fēng)燥，發(fā)動(dòng)機(jī)噪音，在高速行駛過程中，這些都是沒法消除的；而對(duì)于接收者，這個(gè)也沒辦法解決。唯獨(dú)能做的，就是改善傳播介質(zhì)，也就是聲音的傳遞者，改善介質(zhì)，阻斷聲波的傳遞。所以就有了汽車隔音。 </p> <p> 很多人都很關(guān)注到底隔音能降低多少，30%，50%，到底多少？全車各個(gè)部位做好，做標(biāo)準(zhǔn)以后，一般在市區(qū)道路行駛中，噪音大概是60分貝，做了隔音以后，大概能降到40分貝左右。這個(gè)就是問題的答案。已經(jīng)非常理想了，要實(shí)現(xiàn)這個(gè)理想的效果，當(dāng)然和專業(yè)的改裝施工分不開的。

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(huì)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。河源原裝汽車隔音方案</p><p
