A Complementary Effect in Active Control of Powertrain and Road Noise in the Vehicle Interior
This study shows that a concurrent active noise control strategy for engine harmonics and road noise has a complementary effect. In particular, we found that engine booming noise is additionally attenuated when road noise control is concurrently used ...
