Confidence when testing under ALL conditions!

GRAS Sound & Vibration, the world leader in automotive acoustic sensors introduces the GRAS Type 147AX CCP Rugged Pressure Microphone for engine noise testing and the GRAS Type 147EB CCP Extra-Rugged Microphone for wheelhouse brake noise testing. Together with the versatile GRAS 146AE CCP Free-field microphone, GRAS now has the strongest and most comprehensive range of microphones for all automotive NVH applications.

The 147AX CCP Rugged Pressure Microphone has been developed as a surface microphone optimised for cold and hot engine noise testing allowing for more efficient testing and repeatable measurements. It introduces a revolutionary form factor, which together with a unique mounting system and new measurement methods, ensures accurate and reliable data.

The 147EB CCP X-Rugged Microphone Set is an extremely robust microphone specially designed and optimised for on-road brake noise testing. The microphone has a three-layer protection of the diaphragm and has been tested with more than 10,000 miles of on-road testing on all surfaces and in all weather conditions.

• Type 147AX is recommended for cold and hot engine noise testing.

• Type147EB is recommend for on-road brake noise testing.

• Type 146AE is recommended for testing pass-by noise, road noise, buzz, squeak and rattle noise as well as power train noise.
