Buzz, Squeak and Rattle Testing (BSR) Top FAQs

Buzz, Squeak, and Rattle (BSR) testing is a crucial aspect of automotive component development, ensuring that vehicles meet the highest standards of comfort and quality. For automotive engineers, understanding and applying BSR testing methodologies can significantly impact the overall driving experience, and help to reduce customer complaints and warranty claims.

BSR testing is essential for any automotive system or subsystem where noise is a potential concern. This includes a wide range of components such as instrument panels, HVAC modules, sunroofs, steering columns, and electronic components, among others. By simulating in-vehicle vibration environments in the laboratory, BSR testing objectively measures the propensity of these components to generate unwanted noises.

The data generated during BSR testing, such as loudness levels, decibel levels, and frequency response functions, provides valuable insights that can be used to refine designs and improve product quality.

Given the critical role of BSR testing in ensuring the quietness and refinement of automotive components, it is imperative for engineers to be familiar in these methodologies. Downloading the BSR Testing FAQ sheet from Intertek will provide detailed answers to common questions, offering further insights into the equipment, procedures, and data involved in BSR testing. By equipping yourself with this knowledge, you can enhance your designs and contribute to the production of quieter, more reliable vehicles.
