New !! GRAS 147AX CCP Rugged Pressure Microphone

A new and innovative paradigm for the comprehensive testing of engine noise has emerged, paving the way for more accurate assessments and solutions in the automotive industry.

Growing customer expectations increasingly push automotive manufacturers to develop noise-reduced cars that enhance the overall driving experience. Therefore, original equipment manufacturers (OEMs) continuously struggle to identify and effectively reduce various noise sources throughout the vehicle. Additionally, the mounting pressure for fast prototyping and shorter “time-to-market” frames underscores the need for improved and more efficient noise, vibration, and harshness (NVH) test methods. Generating reliable and accurate data is critical in this complex process, and it requires the utilization of the best measurement microphones available, along with a commitment to constantly improving the measurement procedures employed in testing.

This is why GRAS has diligently developed a new surface microphone that is specifically optimized for both cold and hot engine measurements, ensuring accurate data collection in a variety of testing conditions.

With its laboratory-grade precision, combined with extreme ruggedness designed to withstand the hot and harsh conditions typically found in an engine bay, as well as an innovative form factor and versatile mounting system, the 147AX microphone (patent pending) is poised to become the preferred solution for testing facilities and automotive professionals around the world.
