Abstract
A sound system and a method for noise cancellation in a room is provided, the method comprising arranging a set of microphones at a distance from an opening in a wall of the room for provision of one or more microphone input signals including a first microphone input signal; arranging a set of speakers in a vicinity of the opening; determining, based on at least the first microphone input signal, one or more output signals for the set of speakers for matching of sound entering the room through the opening; generating the one or more output signals; and outputting sound signals based on the one or more output signals with the set of speakers.
Claims21
A method for noise cancellation in a room, the method comprising:
- arranging a set of microphones at a distance from an opening in a wall of the room for provision of one or more microphone input signals including a first microphone input signal;
- arranging a set of speakers with respect to the opening, wherein at least some of the speakers are arranged across the opening to form an uneven coverage of an area of the opening;
- determining, based on at least the first microphone input signal, one or more output signals for the set of speakers for matching of sound entering the room through the opening;
- and
- outputting sound signals by the set of speakers based on the one or more output signals.
A sound system for noise cancellation in a room, the sound system comprising:
- a set of microphones for provision of one or more microphone input signals including a first microphone input signal;
- a set of speakers;
- and
- a processing device connected to the set of microphones and to the set of speakers, the processing device comprising a signal processor;
- wherein the signal processor is configured to determine one or more output signals for the set of speakers for matching of sound entering the room through an opening in a wall of the room, wherein the one or more output signals are based on at least the first microphone input signal, and wherein at least some of the speakers are arranged across the opening to form an uneven coverage of an area of the opening;
- and
- wherein the set of speakers is configured to output sound signals based on the one or more output signals.
