主权项 1. A device comprising: at least one computer readable storage medium bearing instructions executable by a processor; at least one processor configured for accessing the computer readable storage medium to execute the instructions to configure the processor for: receiving a noise signal from at least one microphone; receiving room information indicating configuration of a room in which multiple speakers are located; receiving speaker location information indicating a location in the room of at least one speaker; receiving listener location information indicating a target listener location; based on at least the room information and listener location information, determining an amplitude and phase, at the target listener location, of noise represented by the noise signal at the target listener location; and based on the room information, speaker location information, listener location information, and determination of the amplitude and phase of the noise at the target listener location, causing the at least one speaker to emit a noise cancelation signal calculated to have an amplitude equal to the amplitude of the noise at the target listener location and a phase opposite to the phase of the noise at the target listener location.
