Engine testing

When it comes to developing engines and conducting tests in order to monitor aircraft noise, meeting the correct standards reduces your costs, enabling you to operate around the clock.

At GRAS we have developed a wide range of acoustic sensors and rugged measurement microphones designed to help you reduce engine noise in order to obviate aircraft noise certification standards.

Our world-class equipment is perfect in all types of applications, including inflight measurements, fly-overs, acoustic vertical testing and land- based rigs.
