1. A method, comprising:
applying a set of initial power and gain parameters for a speaker;
playing a stimulus signal via the speaker, wherein the stimulus signal comprises a multitone signal;
detecting the stimulus signal at a first microphone a first distance away from the speaker and at a second microphone a second distance, further than the first distance, from the speaker;
determining the multitone signal is detected at one of the first microphone and the second microphone at a target sound pressure level (SPL) threshold;
filtering the multitone signal via a plurality of filters equal to a number of tones associated with the multitone signal to remove false speaker detection sounds;
responsive to the target SPL threshold being detected, terminating the multitone signal;
determining a gain at the microphone locations based on a difference of the sound pressure levels at the microphone locations and a sound pressure level at a predefined distance from the speaker; and
applying the gain to the speaker output.
