摘　　要：制动噪音来自摩擦产生的自激振动,经由声压波传送到人耳,俗称汽车制动NVH,属于汽车舒适性领域;制动噪音通常用振动强度以声压级dB来表示。人类对噪音的敏感频率范围通常在20至20000Hz。不同国家地区对制动噪音的敏感重视度不一样,通常中日韩等亚洲和北美地区的关注度要明显高于欧洲。为此我们有必要对中国汽车市场的制动噪音技术进行深入探讨研究。Brake noise are from the self-motivated vibration producing by friction behavior,and will be transferred to Man's ear via sound pressure wave,which is also called Automobile NVH and belongs to field of Auto Comfort.Brake noise is generally described with vibration Strength by sound pressure dB.Men's sensible Noise frequency are between 20~20000Hz.Different Country has different view of sensibility to the brake noise,i.e.in Asia and north America like China,Japan…has more focus on the brake noise than Europe.So it's very necessary to have a deep research on brake noise in China Auto Market.
