Abstract
An electronic device that provides closed-loop adaptation of 3D sound or a sound field is described. Based at least in part on information about an environment, the electronic device may determine a location of at least an individual relative to location of the second electronic device. Then, based at least in part on the determined location and a predefined acoustic response of the second electronic device, the electronic device may calculate an acoustic radiation pattern of the second electronic device. This acoustic radiation pattern may have a beam with a principal direction corresponding to the determined location, and the acoustic radiation pattern may, at least in part, limit sound distortion of the second electronic device when the second electronic device outputs audio content using the acoustic radiation pattern. Next, the electronic device may provide the audio content and second information specifying the acoustic radiation pattern for the second electronic device.
