Dynamically adapting sound based on background sound
First Claim
1. An electronic device, comprising:
- an interface circuit configured to communicate with a second electronic device, wherein the electronic device comprises a circuit, software executed by a processor or both that is configured to;
acquire sound measurements for an environment, wherein the sound measurements correspond to ambient noise in the environment, wherein the sound measurements comprise passive sound measurements during a quiet time interval when a speaker is not outputting sound into the environment, and wherein the ambient noise is associated with diffuse energy that is coupled into the environment and is filtered by a geometry of the environment;
determine, based at least in part on the sound measurements, a characteristic of the environment;
calculate, based at least in part on the determined characteristics, an acoustic radiation pattern; and
provide, from the interface circuit, audio content and second information specifying the acoustic radiation pattern for the second electronic device.

Abstract
An electronic device that dynamically adapts sound based at least in part on spatial information determined from ambient or background sound is described. Based at least in part on sound measurements corresponding to ambient noise in an environment, which may include a second electronic device, the electronic device may determine a characteristic of the environment. For example, the characteristic may include: a size of the environment, an acoustic mode of the environment and/or a reverberation time of the environment, which is associated with at least a frequency. Then, based at least in part on the determined characteristics, the electronic device may calculate an acoustic radiation pattern. Next, the electronic device may provide audio content and second information specifying the acoustic radiation pattern for the second electronic device.
