Abstract
Sealing and sound-package performances can directly affect the NVH level inside cars. In this article, the problem of the high interior noise and the poor sound quality of a car at idling is studied. Using noise source separation testing method, the engine noise is found to be the main noise source inside the car. Through the dash-hole sealing improvement and sound-package improving of the noise propagation path, the engine noise is blocked and the interior sound quality is improved effectively.关键词
