济南汽车隔音http://www.sdcarmusic.com/提醒无论是在怠速还是日常行驶的车速下，安装发动机盖隔音棉的效果其实并不理想，对车厢内隔音起到的作用不大，而在高速行驶时，车的风噪声则已盖过发动机的声音了。所以在日常驾驶，如果只想靠安装发动机隔音棉来改善车厢内噪音的话，是不现实的。不过在车辆在静止急加速起步的过程中，有无隔音棉的区别还是可以感受得出来的。
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.
