Abstract
Systems and methods for mapping noise via a plurality of playback devices within an environment are disclosed herein. In one example, a plurality of playback devices can each output audio and also detect sound within the environment to obtain respective sound data specimens. For each playback device, the respective sound data specimen can be analyzed to obtain a respective noise determination. A spatial map of the noise determinations within the environment can then be constructed. A visual representation of the spatial map can further be presented to a user. In response to the noise determinations and/or a user input, the audio output via at least one of the playback devices can be modified, for example to mask or suppress noise within one or more regions of the environment.
