    车子在行驶的时候,难免会有噪音,噪音的来源是很多的,种类同样有很多,特别是发动机的噪音,大家可以通过做btc365来给车子降低噪音,享受更好的汽车音乐。汽车噪音从种类上区分主要分以下三种:
    一、高频噪音,主要包括发动机咆哮声、砂石敲击底盘声音、车体部件结构不紧产生的震动声。高频声音的特点就是清脆、响亮、易察觉,可以做发动机、引擎盖、U型槽隔音,如果风燥很大,还会考虑做底板隔音等,做汽车隔音,主要还是根据车子具体的部位来做。
    High-frequency noise, including engine roar, gravel percussion sounds chassis, body parts structure does not bear the sound vibrations produced.

    二、低频声音,这个主要包括路噪、胎噪、颠簸时减震的声音、怠速时排气管的气浪冲击。低频声音的特点是沉闷、不清晰,有时候,我们被低频噪音搞得头痛,还找不到原因。
