车载装备噪声控制探讨

The Research on Noise Control of Vehicle Equipment

车载装备(如柴油发电车)的低噪声设计主要是针对装备工作时的噪声组成、特点,结合噪声的控制方式和阻性、抗性消声原理把噪声控制在声场内,限制其传播,采取减震、隔声和消声等措施,使其强度和能量衰减,从而达到低噪声工作的目的。

Adopting the noise controlling methods and silencing theory, low-level noise design of vehicle equipments is mainly focus on the composition, the characteristics of the equipments working noise to control the noise within its sound field and limit its spreading. Shock absorption, sound insulation and silencing methods are used to make noise intension and energy attenuate, thus the objective of lowering noise can be reached.
