噪声振动术语：Boom: Continuous low frequency sound, 20 -80 hz ( note: the frequency ranges given here are approximate). This is commonly a pure tone i.e. a sign wave at a specific frequency.连续的低频噪声，大约20-80Hz的纯音。Buzz: High frequency vibration (>50 Hz) {Note-Location needs specification}大于50Hz的高频振动Clunk: A transient, low frequency, broadband noise.瞬态的，低频宽带噪声Drone: Similar to boom but at a higher frequency (100-200 hz range).同Boom类似，但频率范围在100-200Hz，经常和Ｂｏｏｍ不区分Growl: A broadband noise in the 100-1000 hz range with a noticeable time variation (modulation).在１００－１０００Ｈｚ之间的宽频噪声，明显随时间波动（调制）Moan: A low amplitude sound in the 80-200 hz range, frequently consisting of one or two tones.８０－２００Ｈｚ之间低幅值噪声，通常由１－２个纯音组成Periods: Peaks in the sound pressure observed as engine rpm increases or decreases. These peaks are usually due to engine mount and accessory resonances.峰值明显随发动机转速升高或降低，通常由于发动机悬置和附件共振引起Rattle: The noise due to the random impact of two surfaces.由于两个面随机撞击产生的噪声Rumble: Rumble is low to mid frequency broadband noise (100 -500 hz) which varies in amplitude.中低频的宽带噪声（１００－５００Ｈｚ），幅值是变化的，比敲击噪声钝，是强烈的断续声，是由非常早期的，或者几个地方表明着火引起的声音。ENGINE Roughness：发动机粗糙声：由不完全燃烧，曲轴的弯曲振动及由此引起的敲击似的声音。调节阀全开时易发生。燃烧压力的不同，曲轴发生弯曲振动，敲击轴承座时发生。Shake: Low frequency vibration低于５０Ｈｚ的低频振动Tick and Hash: Miscellaneous noises with considerable time variation.随时间变化很大的其它噪声Whine: A mid to high frequency sound (200-2000 hz) consisting of a tone and harmonics.由纯音和谐次组成的中高频噪声（２００－２０００ＨＺ）Metal Noise：金属所发出的异响。AT车在怠速时，在D档发生的Kon-kon_声和LPG车在怠速时发出的哗啦声。操作工况术语Idle: Neutral gear for MT，N-R-D position forATＭＴ为空挡，自动挡有Ｎ－Ｒ－Ｄ三个位置Tip-in轻点油门踏板: Light acceleration with small gas pedal "tip-in" (usually at cruise speed, 55-65 mph).Tip-out轻松油门踏板: Light deceleration with small gas pedal "tip-out" (usually at cruise speed, 55-65 mph).Lugging高扭矩低转速（高档低转速拖挡）: High torque and low rpmWOT节气门全开加速: Wide open throttle accelerationCruise匀速行驶: Constant speed, particularly 55-65 mph
