1. A method, comprising:
identifying a plurality of speakers and microphones;
assigning a preliminary output gain to the plurality of speakers used to apply test signals;
recording chirp responses from the microphones based on the test signals;
deconvolving the chirp responses to determine a corresponding number of impulse responses; and
obtaining a sound pressure level (SPL) level based on an average of SPLs of the microphones.
