Buzz, Squeak, and Rattle (BSR) testing plays a pivotal role in eliminating unwanted noises in automotive products thus enhancing user satisfaction and perceived quality. This testing simulates real-world conditions to identify the sources of buzzing, squeaking, and rattling noises within product components. By pinpointing these noises early in development, engineers can address and mitigate them through design, material, and assembly process adjustments, ensuring products meet high-quality standards.

Employing advanced audio equipment and vibration analysis tools, BSR testing accurately locates noise sources, allowing for precise corrections. This essential quality assurance step not only improves product reliability but also bolsters the brand's reputation for excellence.

BSR testing has become even more critical in the development of electric vehicle interior components as the quieter ride makes it easier for occupants to hear any unwanted noises.

Our experts have answered some of the most frequently asked questions about BSR testing, including:
