GRAS Sound & Vibration UK increases focus on aerospace and defence

April 16, 2019 / aero-ma

Reduction of noise emissions is critical, with manufacturers demanding increasingly sophisticated measurement instruments to ensure the continued development of quieter aircraft.All applications bring their own challenges but aerospace testing can be one of the harshest, pushing microphones to their limits. Measurements often need to be conducted in high speed, turbulent air-flows, where it is vital that the microphone itself does not affect the results, and where the testing equipment has to be durable under extreme conditions. Often there is only one opportunity to record data so validation is vital.GRAS UK has become an integral supplier to the aerospace and defence industries, dedicated to finding new ways of testing. From standard microphones, customised flyover arrays or microphones for extreme sounds pressures, the company’s solutions help manufacturers develop the technically advanced aircraft of the future.
