1. A method, comprising:
determining a multitone signal is detected at a plurality of microphones 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;
determining a gain at microphone locations based on a difference of SPLs at the microphone locations and a SPL at a distance from a speaker; and
applying the gain to a speaker output.
