Summary:

BSR noise is an essential parameter for customer discomfort. According to a market survey, squeaks and rattles are the third most crucial customer concern in cars after six months ofownership. The high quality acoustic environment of a car, annoying noises like buzz, squeak, and the rattle is related to various parameters such as material assembly, tolerance, ageing,humidity, surface contact, and surface hardness. BSR is originated from frictional movement between two parts or from the impact between two parts. The rattle noise is caused when surfaces close to each other move perpendicular to each other due to insufficient attachments or insufficient structural strength. In our study, we have shown the impact of various front suspension component in front suspension assembly on BSR noise and also the method to detect and attenuate thesame. A methodical analysis process is shown to identify the contributing part and resolve the BSR issue. A detailed case study on vehicle level is carried out to achieve the requiredBSR score
