Abstract:

In order to determine whether the specific parts has BSR phenomenons, Squeak and Rattle shaker system are employed for the subjective evaluation of BSR tests. Subjective evaluation relies heavily on experienced engineer and is less coherent. Based on the detailed description of seat S&R test method , the method of evaluating the seat noise is discussed. Through the analysis of the subjective evaluation results and the acoustic parameters data, the objective acoustic parameters which can reflect the subjective evaluation results are summarized. The method is close to the engineering practice and can identify the BSR problem.
