Abstract

A system and method for automatically controlling the timbre of a sound signal in a listening room are also disclosed, which include the following: generating an acoustic sound output from an electrical sound signal; measuring the total acoustic sound level in the room and generating an electrical total sound signal representative of the total acoustic sound level in the room, wherein the total acoustic sound comprises the acoustic sound output generated from the electrical sound signal; and adjusting the gain of the electrical sound signal dependent on a room-dependent gain signal, the room-dependent gain signal being determined from reference room data and estimated room data.
