The internal sound includes first internal sound components and second internal sound components, the first internal sound components not corresponding to the at least one desired sound pattern and the second internal sound components corresponding to the at least one desired sound pattern. The anti-sound is further configured to attenuate the first internal sound components, and to amplify, not attenuate, or attenuate to a lesser degree than the first internal sound components the second internal sound components.

摘要： An example active road noise control includes generating with a sensor arrangement a primary sense signal representative of at least one of accelerations, motions and vibrations that occur at a first position, and providing a noise reducing signal by processing the primary sense signal according to an adaptive mode of operation or a non-adaptive mode of operation. It further includes generating within the vehicle body noise reducing sound at the second position from the noise reducing signal, evaluating the primary sense signal and controlling the processing of the primary sense signal so that the primary sense signal is processed in the adaptive mode of operation when the magnitude of the primary sense signal undercuts a first threshold and in the non-adaptive mode of operation when the magnitude of the primary sense signal exceeds a second threshold, the first threshold being equal to or smaller than the second threshold.

摘要： An active road noise control system method for a vehicle includes picking up noise at a multiplicity of positions in or on the vehicle and generating a multiplicity of noise sense signals representative of road noise originating from a road noise source in or at the vehicle, and processing, according to a beamforming scheme, the multiplicity of noise sense signals to generate a reference signal and to provide a sensitivity characteristic for picking up the noise that comprises one main lobe directed to the road noise source. The system and method further includes iteratively and adaptively processing the reference signal to provide a noise reducing signal, and generating at one or more positions in an interior of the vehicle, from the noise reducing signal, noise reducing sound at a listening position in the interior of the vehicle.
