inlet noise meaning in English
进气道噪音
Examples
- Nearly all engines are equipped with air cleaners , which help reduce the air inlet noise to a secondary sound source
一般发动机均装有空气滤清器，进气噪声即可有较大衰减，成为次要声源。 - Aerodynamic noises radiated directly to the atmosphere include the air inlet noise , the exhaust noise and the cooling fan noise
直接向大气辐射的空气动力噪声包括：进气噪声、排气噪声、冷却风扇噪声。 - The air inlet noise is related to designing factors like the air inlet mode , the inlet valve structure , the cylinder diameter as well as the cam curve
进气噪声与发动机的进气方式、进气门结构、缸径、凸轮型线等设计因素有关。 - For turbo - charged engines , due to the high rotating speed of the turbocharger , the air inlet noise is much higher than non - turbo - charged engines
对于采用涡轮增压的发动机，由于涡轮增压器的转速一般较高，因此其进气噪声明显高于非涡轮增压的发动机。 - For one same engine , the noise level is highly dependent on the rotation speed . when the rotation speed doubles , the air inlet noise can increase by 10 to l5db ( a )
对于同一台发动机来说，受转速的影响最大，转速提高一倍可导致进气噪声增加10 ~ l5db （ a ） 。
