Fan-noise-in-the-acoustic-laboratory

Acoustic labor in Ottobrunn. The compliance with noise regulations at airports is a very critical issue for aerospace industry. The launch of turbofan engines with a high bypass ratio reduce significantly the overall perceived noise level of commercial aircrafts. EADS-CRC investigates the physics of the noise generating process of the tonal fan and develops new active, passive and adaptive concepts to meet the demands of the future. These concepts comprise multi-channel Active Noise Control, multi degree of freedom liners and new resonator strategies.
