Abstract
A system and method for quieting unwanted sound. As a non-limiting example, various aspects of this disclosure provide a system and method, for example implemented in a premises-based or home audio system, for quieting unwanted sound at a particular location.
Claims21
1-22. (canceled)
An audio system comprising:
- at least one module operable to, at least:
- characterize a relationship between a sound signal and a received sound, where the sound signal is used to cause a loudspeaker to output an output sound, and the received sound is the output sound as received at a location;
- identify an unwanted sound at the location;
- determine, based at least in part on the characterized relationship, a cancellation signal that, when used to cause the loudspeaker to output a counteracting sound, will quiet the unwanted sound at the location;
- and
- generate the cancellation signal to cause the loudspeaker to output the counteracting sound,
- wherein the at least one module is operable to determine the cancellation signal by, at least in part, operating to, independent of user input, set a magnitude of the cancellation signal to a level below that determined for ideal cancellation.
4 more elements
An audio system comprising:
- at least one module operable to, at least:
- identify an unwanted sound at a location, by, at least in part, operating to receive the unwanted sound using at least one sound sensor positioned at a distance away from the location at least one fourth of a wavelength of a lower bound of a frequency band of sound to be counteracted;
- identify a loudspeaker to utilize to quiet the unwanted sound;
- determine a counteracting sound that, when output by the loudspeaker, will quiet the unwanted sound at the location;
- and
- output the counteracting sound at the loudspeaker.
3 more elements
An audio system comprising:
- at least one module operable to, at least:
- identify an unwanted sound to counteract;
- analyze the identified unwanted sound;
- select, based at least in part on the analysis of the identified unwanted sound, between a plurality of different types of countermeasure strategies for counteracting the unwanted sound;
- and
- implement the selected strategy,
- wherein the plurality of different types of countermeasure strategies comprises:
- a first countermeasure strategy comprising performing sound cancellation;
- and
- a second countermeasure strategy comprising performing sound masking.
