After maintenance, aircraft engines must be tested. However, the testing of aircraft engines often causes a lot of noise nuisance. 4Silence makes products for noise reduction along (motor) roads and railroads. Possibilities are being investigated to realize a solution for test run noise with the unique invention of 4Silence. First research results indicate a startling noise reduction! In the coming period, this application will be tested in practice at Twente Airport and at Rotterdam The Hague Airport.
The consultancy Adecs Airinfra is also involved in the research.
4Silence is located at Technology Base in the municipality of Enschede.
