Aerospace & Defense


All industry applications bring their own challenges, but aerospace testing can be one of the harshest, pushing microphones to their limits. At GRAS we know that measurements often need to be carried out in high speed, turbulent air-flows, where it is vital that the microphone itself does not affect the measurements - and where the testing equipment has to be durable under extreme conditions. Often you only have one chance to record data so validation is vital.

And because we work closely with you, we are well aware of your needs and the challenges you face in such a unique industry. If we can improve your testing, you can improve your products.

GRAS has become an integral part of the aerospace industry, dedicated to finding new ways of testing. From standard microphones, customized flyover arrays or microphones for extreme sound pressures, GRAS has the right microphones to help you develop tomorrow’s airplanes today.
