AB  - The presented active road noise control system uses multichannel reference signals provided by digital automotive accelerometer sensors strategically placed on suspension or chassis to predict the structure-born road noise transferred from the tires into the cabin. Omni-directional microphones installed in the vehicle roofline, close to the passenger’s ears, are used as error microphones. Once activated, the system is minimizing the road noise and establishing a quite zone in the proximity of these locations. Only the standard built-in vehicle loudspeakers are used as actuators. The presented digital audio amplifier platform compromise the complete multichannel control and update algorithm processing in parallel with an audio processing. Several road noise scenarios from different vehicles are used to indicate state-of-the-art road noise reduction performance.
