Element’s large multiaxial silent shaker can perform buzz, squeak, and rattle (BSR) testing with fast turnaround times on automotive components up to 700lbs, to help manufacturers create quieter products.

With the increasing demand for electric vehicles, automotive manufacturers will see an ever-increasing need to evaluate their components’ buzz, squeak, and rattle performance due to lack of engine noise. BSR testing allows manufacturers to modify their designs before the component becomes a problem for the consumer or a warranty issue for the manufacturer.

Buzz, squeak, and rattle testing capabilities

Element Warren houses one of the largest silent shakers in the mid-west. The 6ft wide by 40in deep table can be used for the BSR testing of automotive components such as consoles, instrument panels, doors, full rows of seats, or quarter car bodies. The 700lb weight limit allows for the vibration of components that would typically be too large or heavy for a silent shaker system. 

Element’s shaker features multiaxis vertical pitch and roll testing as well as sequential 4-axis testing to mimic real-world road conditions. Configurations of smaller components can also be run simultaneously, significantly reducing turnaround time.

Multi-channel data collection

Element conducts BSR testing in a semi-anechoic chamber with an advanced twelve-channel sound collection system for acoustic data collection. With twelve ½ inch pre-polarized free-field microphones, the test set-up ensures maximum data capture so our experts can quickly localize the source or cause of an unwanted sound.
