Abstract:
A system for generating a silent zone at a listening position is provided. The system includes a loudspeaker, an error microphone, a microphone array, and a noise controller. The loudspeaker is configured to radiate sound that corresponds to a sound signal. The error microphone is configured to pick up noise radiated by a noise source and the sound radiated by the loudspeaker via a secondary path. The microphone array is configured to pick up noise radiated by a noise source and the sound from the loudspeaker. The microphone array is configured to generate corresponding array signals. The noise controller is configured to receive a noise signal representative of noise radiated by the noise source and to filter the noise signal with a controllable noise reduction transfer function. The noise controller is further configured to control the noise reduction transfer function based on the noise signal and a virtual error signal.

Claim (Index 4):
The system of  claim 1 , wherein the noise controller is further configured to filter the noise signal with a transfer function that models a transfer function of the secondary path prior to the noise controller controlling the noise reduction transfer function.
