Abstract
In the future, the requirements of acoustic behavior in air intake systems will continue to increase. Common passive or adaptive acoustic measures will not be able to reach higher standards while maintaining reasonable costs and packaging specifications. For new engines complying with future legislative limits in noise emissions, it will be necessary to develop active systems.
This investigation analyzes the possibility of integrating an active noise cancellation system within the air intake system. An air intake system was optimized by one dimensional calculation. The components of the active system were defined according to the computational results. The acoustical feasibility of an active system were then measured and analyzed on an anechoic engine dynamometer.
