EU noise program meets goals halfway
The European Union’s research program on noise reduction, Silence(r), officially ended in June with promising results.

The European Union’s research program on noise reduction, Silence(r), officially ended in June with promising results. It explored all noise sources, from engines to landing gear and flaps. However, although it achieved a reduction of five decibels in aircraft noise, several more leads need to be developed to reach the ambitious target of cutting a full 10 dB from average noise levels by 2020.

Silence(r) brought together 51 companies–including Airbus, Rolls-Royce, MTU Aero Engines and Snecma–as well as various research centers and universities. The project’s overall budget was ?112 million ($150 million), about half of which the European Commission funded. Snecma’s Eugene Kors was the program coordinator.
