Summary:

Recent advances in automotive noise control engineering have reduced the general level of noise in the passenger car compartment and focused more attention on irritating noises. Buzz, Squeak and Rattle (BSR) have surfaced as major concerns. Customers increasingly perceive squeak and rattle as direct indicator of vehicle build quality and durability as revealed from the J. D. Power surveys. The high profile nature of squeak and rattle has motivated the manufacturers to pay attention during early phase of vehicle development program. Traditional methods of prevention and elimination of squeak and rattle have been found to be no longer sufficient to develop acceptable products in shortened product development cycle. Basic causes, design guidelines and validation technique using laboratory simulation and digital data acquisition have been successfully developed to push the BSR prevention process upstream in the development cycle.A test procedure to map the vehicle BSR performance with the use of laboratory simulation and digital data acquisition tools has been developed. The vehicle BSR performance is evaluated based on the subjective rating system. As commitment towards customer to meet his expectations in quality right from purchase till the useful life of vehicle, the vehicle BSR performance is monitored till the end of life. Lab simulation technique allow determination of sub-system or prototype vehicle degradation much early in the development process. Simulation is used to map the progression of noise with respect to vehicle life and usage conditions. Targeting at reducing noises after durability exposure, effectively later in the vehicle life, is crucial in ensuring new vehicle quality
