Abstract
A system reduces power consumption by optimizing a selection of acoustic sensors of a sensor array based on environmental parameters of a local area. The system includes the sensor array including the acoustic sensors configured to detect sound in a local area, and processing circuitry. The processing circuitry is configured to: determine an environmental parameter of the local area; determine a performance metric for the sensor array; determine a selection of a subset of acoustic sensors from the acoustic sensors of the sensor array that satisfies the performance metric based on the environmental parameter of the local area; and process audio data from the subset of the acoustic sensors of the sensor array.
