Abstract
A system and method of controlling loudness of an electroacoustic transducer may include: receiving a transfer function data element representing a transfer function between (a) electrical input and (b) sound pressure level (SPL) output of the electroacoustic transducer; applying the transfer function on an incoming electrical signal, to obtain an expected SPL signal, representing expected SPL of the electroacoustic transducer in response to the incoming electrical signal; identifying at least one fundamental acoustic tone in the expected SPL signal; producing at least one electrical compensation signal, corresponding to an acoustic harmonic of the at least one identified fundamental acoustic tone; and controlling the loudness of the electroacoustic transducer, based at least in part on the at least one electrical compensation signal.
