Microphones Automotive

All modern vehicles have to comply with and be compliant with the regulations relating to the noise emissions. It is a fundamental parameter for the comfort of the people inside the car who is outside. To meet these standards, use a full-scale prototype, or the various parts that make up a vehicle. The tests are performed to measure noise, vibration, and robustness (Noise, vibration and harshness NVH).

In the automotive industry, and engineers work to optimize the driving experience and reduce the noise from the vehicle with the surrounding environment. The sound quality and the comfort of the cabin had a special attention and have become a competitive differentiator for manufacturers of vehicles. G. R. A. S. provides the automotive industry for years now. The catalog of the G. R. A. S. offers a wide range of microphones. There are various categories of microphones that are used for automotive applications: microphones, automotive surface, the array of microphones measurement microphones to external. The microphones that allow the measurement of sound pressure and sound power originated from different sources, and components. There are types of microphones automotive specific for different types of components and noise.

The types of noise can be classified in English, according to this nomenclature: Engine Noise, Exhaust Noise, Tire Noise, Brake Noise, Interior Noise, Pass-by Noise, Sound Quality, Car Audio, Wind noise.
