GRAS 147EB CCP X-Rugged Microphone Set



Microphone for wheelhouse brake noise testing

Silent brakes are important to car owners and noisy brakes quickly translate into costly after-sales service for the manufacturer. This is why brake noise testing is so important to auto manufacturers and sub-suppliers of brake components.

Testing of brakes is not complete without comprehensive road testing. The countless different conditions that arise during real-life use need to be investigated. To enable more efficient road testing of brakes, an extremely robust microphone that can survive thousands of miles of road testing is needed.


This is why we at GRAS have developed a new rugged microphone optimized for the rough conditions in the wheelhouse. A robust microphone that can withstand prolonged exposure to extreme temperature variations, water, salt, dust, snow and impacts from gravel.
