Abstract: Devices, methods, systems, and media for selectively cancelling sounds at a listener's location are described. Sound sources are identified in the listener's environment using microphones and/or remote devices associated with specific sound sources. A user is presented with information identifying the sound sources, including spatial information, and prompting the user to select one or more of the sound sources. After the user designates a sound source as noise, microphones are used to monitor for sound originating from the designated sound source, and the audio information captured by the microphones is processed to generate an anti-noise signal presented to the listener to cancel sounds originating from the selected sound source. A user may designate multiple sound sources as noise and leave other sound sources unfiltered. The techniques may be used in single-listener and multi-listener applications, and in listening and speaking applications.
