| Abstract: | 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. |
