Measure external noise E175-E2

Measure external noise E175-E2

It took several weeks for our team of 30 engineers and technicians to set up sensitive equipment a few months ago at our test facility at Gavião Peixoto in central Brazil. The devices measured the takeoff and landing noise from our newest E-Jet, the E175-E2, as the aircraft moves towards certification.

The process is highly coordinated between teams on the ground and the pilots who must fly the E2 at varying angles, speeds, and altitudes in order to build a noise profile for the aircraft from nearly 70,000 sound samples generated per second captured on 96 microphones.

In this video, our test flight engineers and pilots explain how the tests are conducted. They also talk about the importance of low-noise aircraft and how the E2s are continually improving to be even more environmentally responsible. In fact, our E2s already comply with the future noise limits for commercial aircraft set by ICAO.
