Assignee: AMAZON TECHNOLOGIES, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A method comprising:
determining first audio input data by a first device, wherein the first audio input data is representative of a first sound;
determining second audio input data by a second device, wherein the second audio input data is representative of the first sound;
determining a first energy value indicative of acoustic energy represented by the first audio input data;
determining a second energy value indicative of acoustic energy represented by the second audio input data;
determining, based on the first energy value being greater than the second energy value, first proximity data that indicates a source of the first sound is closer to the first device than the second device;
determining, based on the first audio input data and the second audio input data, a time difference of arrival (TDOA) value of the first sound;
determining, based on the TDOA value, second proximity data that indicates the source of the first sound is closer to the first device than the second device;
determining a noise source based on one or more of:
the first audio input data,
the second audio input data,
the first energy value,
the second energy value, or
the TDOA value;

determining the second device is closest to the noise source; and
based on the first proximity data and the second proximity data, sending, by the first device, third audio input data to a third device.
