• The cooling fan noise comprises the rotation noise and the turbulent noise
  风扇噪声由旋转噪声和湍流噪声构成。
• The turbocharger noise is formed by the rotation noise resulting from the periodical air cutting of the fan blade and the turbulent noise of high - speed gas flows . as a continuous high frequency noise , it mainly falls between the 500 to 10 000 hz range
  涡轮增压器的噪声是由于叶片周期性地切割空气产生的旋转噪声和高速气流形成的湍流噪声而形成的，是一种连续性的高频噪声，主要分布在500 ~ 10000hz的频率范围。
• At the same time , when the gas flow passes the flow area of the inlet valve at a high speed , turbulent throw - outs will appear and lead to the generation of high frequency noises . as the flow area of the inlet valve keeps changing , the turbulent noise is of fixed frequency range ( generally over 1 000 hz )
  与此同时，当气流以高速流经进气门流通截面时，产生湍流脱体，导致高频噪声的产生，由于进气门通流截面是不断变化的，因此湍流噪声具有一定的频率范围，主要集中在1000hz以上的高频范围。
• The exhaust noise contains complex noise elements , including the exhaust noise with a base frequency measured in the number of exhausts in unit time , the resonance noise of the gas column in the pipe , the gas stream blowing noise at the exhaust manifold , the exhaust gas jetting and impact noise , the helmholtz resonance noise of the cylinder , the karman eddy noise and the turbulent noise inside the exhaust system
  排气噪声包含了复杂的噪声成分：以单位时间内排气次数为基频的排气噪声、管道内气柱共振噪声、排气歧管处的气流吹气噪声、废气喷注和冲击噪声、汽缸的亥姆霍兹共振噪声、卡门涡流噪声及排气系统内部的湍流噪声等。
• The former one is a product of the pressure pulsation resulting from the fan blade periodically cutting the air , with the blade passing frequency as its base frequency and accompanied by higher harmonics . the wide - band turbulent noise is formed when the rotating fan forces the surrounding air to produce turbulent throw - outs and results in gas thickening and thinning processes
  旋转噪声是由于风扇的叶片周期性地切割空气，引起空气的压力脉动产生的，以叶片通过频率为基频，并伴有高次谐波。湍流噪声是由于风扇运动导致的周围空气发生湍流脱体，使空气发生扰动，形成气体的压缩与稀疏过程而形成的，是一个宽频带噪声。
