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 8):
A method for generating a silent zone at a listening position, the method comprising:\n radiating with a loudspeaker disposed adjacent to the listening position sound that corresponds to a sound signal; picking up with an error microphone disposed adjacent to the listening position noise radiated by a noise source via a primary path to the listening position and the sound radiated by the loudspeaker via a secondary path to the listening position, generating, with the error microphone, a corresponding error signal; picking up with a microphone array comprising a multiplicity of array microphones disposed above the listening position noise radiated by a noise source via a primary path to the listening position and the sound radiated by the loudspeaker via a secondary path to the listening position, generating, with the microphone array, corresponding array signals; and controlling noise by receiving a noise signal representative of noise generated by the noise source and filtering the noise signal with a controllable noise reduction transfer function to generate the sound signal supplied to the loudspeaker, wherein controlling noise further comprises controlling the noise reduction transfer function based on the noise signal and a virtual error signal, and generating the virtual error signal based on the error signal and the noise signal filtered with a Green's function matrix, the Green's function matrix being configured to be controlled by the array signals.
