濟南汽車隔音http://www.szanyuda.com/分析發動機隔音棉目的是減少噪音，實質上也起到了隔音的作用，間接上也對發動機起到隔熱的作用，從上述可以看出汽車隔音棉是有作用的，但不是特別明顯。
Jinan car noise analysis engine noise cotton aims to reduce noise, also played a role in virtually soundproof, indirectly also play a role in engine insulation, can be seen from the above vehicle noise cotton is useful, but it is not obvious.

濟南汽車隔音http://www.szanyuda.com/提醒無論是在怠速還是日常行駛的車速下，安裝發動機蓋隔音棉的效果其實并不理想，對車廂內隔音起到的作用不大，而在高速行駛時，車的風噪聲則已蓋過發動機的聲音了。所以在日常駕駛，如果只想靠安裝發動機隔音棉來改善車廂內噪音的話，是不現實的。不過在車輛在靜止急加速起步的過程中，有無隔音棉的區別還是可以感受得出來的。
Jinan car sound to remind both at idle speed or daily driving, install hood cotton insulation effect is not ideal for the role of sound inside is not, and at high speeds, the car's wind noise already overshadowed by the sound of the engine. Therefore, in daily driving, if you want to install the engine noise cotton by improving vehicle interior noise, then, it is unrealistic. However, the vehicle is still in the process of rapid acceleration start, the distinction between whether the cotton insulation can still feel too out.
