Noise Testing

Whilst a vehicle may be completely quiet in most conditions, a certain temperature and humidity combination might cause mating structures to expand or contract and introduce a coefficient of friction that creates an annoying audible noise.

We use a dedicated vibration shaker to evaluate the level of buzz, squeak, and rattle (BSR) performance of assembled components using a variation of nine typical road surfaces to replicate normal driving conditions. It takes a trained ear and years of experience to ensure noise caused by vibrating surfaces or friction is kept to an acceptable level.
