濟南汽車音響改裝http://www.szanyuda.com/介紹目前國內流行的汽車車廂隔音技術汽車室內消音降噪工程，都是對這幾個噪聲源進行防治，以達到隔絕噪聲進入車廂的目的。一臺中高檔轎車經過隔音施工后，其行駛噪聲平均能降低6--7分貝。

1、濟南汽車音響改裝在引擎蓋粘貼引擎蓋覆膜，吸收引擎運轉噪音；在車廂內加裝降震消音貼膜及吸音王復合材料，緩解底盤件在高速行駛時引起的共鳴，減少由于輪胎轉動所產生的路面噪音傳遞。
Ji'nan car audio conversion in the engine cover hood film paste, absorb the engine running noise; the installation of seismic reduction silencing film and sound-absorbing Wang composite in the compartment, alleviate the chassis parts caused at high speeds due to resonance, reduce road noise generated by the rotation of the transfer of tire.

2、濟南汽車音響改裝在車門飾板內貼上專用隔音王貼膜，降低行車時車門鈑金件因較薄而產生的共振，減少車門飾板的松脫，降低由于金屬疲勞及車身扭動時產生的雜音。
Ji'nan car audio conversion in the door trim panel is pasted in the special noise Wang film, reduce driving door sheet metal parts due to thinner resonance, reduce the door trim panel loose, reduce due to metal fatigue and body twisting murmur.

3、濟南汽車音響改裝采用密封條，強化Ａ、Ｂ、Ｃ柱密封性，補強后座側板，提高車身的結構性，有效降低噪音；在車門飾件上貼中頻吸音王，加裝車門隔音條以加強密封性，減小共鳴聲及降低汽車高速行駛的風噪聲。
Ji'nan car audio with sealing strip, enhanced A, B, C column sealing, reinforcing the backseat plate, improve the body structure, effectively reduce the noise; post intermediate frequency sound-absorbing the king in the door trim, the installation of door sound insulation strip to enhance sealing, reduce resonance sound and reduce the noise of high speed automobile.

4、濟南汽車音響改裝http://www.szanyuda.com/在前后輪葉子板處噴涂噴立靜隔音材料，減少行駛時避震器傳入的異音，抑制輪胎與路面、鈑金件所產生的撞擊雜音；在車廂內頂粘上一層高性能頂級隔音王，有效阻隔太陽酷曬，防止車廂溫度直線上升，減少車頂鋼板震動的共鳴聲。
Ji'nan car audio conversion spray sprayed on leaves at the front and rear wheel plate vertical static sound insulation materials, reduce the abnormal sound when driving shock absorber incoming, inhibition of the tire and the road surface, sheet metal impact arising from the noise; in the interior roof top stick on a high performance noise Wang, effectively blocking the sun and cool air, prevent the interior temperature rise in a straight line the roof plate, reduce the resonance vibration.
