Abstract
The disclosed computer-implemented method may include accessing environment information identifying an undesired sound source within an environment. The method may further include determining, based on the accessed environment information, a spatial location of the undesired sound source in the environment that is to be attenuated using an active noise cancelling (ANC) signal. The method may also include forming a microphone beam, using two or more microphones, directed at the determined spatial location, where the microphone beam is configured to capture audio information from the determined spatial location. Still further, the method may include generating an ANC signal using the audio information captured using the microphone beam, and playing back the generated ANC signal to attenuate the undesired sound source at the determined spatial location. Various other methods, systems, and computer-readable media are also disclosed.
