US Patent 9794720 Acoustic position measurement

Disclosed herein are example techniques for acoustic position measurement in an example listening environment. One example includes determining a requirement for position information of a speaker-equipped device within a room in which a media playback system is located, and in response to determining the requirement for position information of the speaker-equipped device, determining a position of the speaker-equipped device relative to a microphone-equipped device of the media playback system based at least in part on a test sound emitted from the speaker-equipped device. After determining the position of the speaker-equipped device relative to the microphone-equipped device, some examples further include configuring one or more audio configuration parameters of the media playback system based on the position of the speaker-equipped device relative to the microphone-equipped device.
