Claim 14:
15. A method comprising:
determining, using a first device, first audio input data representative of a sound;
determining, based on the first audio input data, a first energy value;
determining, using a second device, second audio input data representative of the sound;
determining, based on the second audio input data, a second energy value;
determining first proximity data, based on the first energy value and the second energy value, the first proximity data indicative of proximity of the first device to a source of the sound;
determining, based on the first audio input data and the second audio input data, a time difference of arrival (TDOA) value;
determining second proximity data based on the TDOA value, the second proximity data indicative of proximity of the second device to the source of the sound;
determining, based on the first proximity data and the second proximity data, that the first device is closest to the source of the sound;
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 that the second device is closest to the noise source; and
sending, by the first device, third audio input data to a third device.
