驾驶室隔声漏声的声压法测量

The Application of Sound Pressure Level Measurement (SPLM) in the Measuring of Sound Isolation and Leak of Vehicle Cab

为了控制车内噪声,研究驾驶室的隔声效果则是必不可少的环节。本文介绍一种简单可行的评价驾驶室隔声漏声的测量方法,并结合实际给出了声压法在驾驶室隔声漏声测量中的应用实例。在没有声学试验室的情况下,该试验方法不失为一项行之有效的方法。

For controlling noise in cab, it is necessary to study the effect of sound isolation of vehicle cab. In this article, a simple and practical method of evaluating sound isolation and leak of cabs is introduced, and an example of cab sound isolation and leak measurement using SPLM has been given. This is an applicable method in field measurement.
