Abstract

The invention provides a sound field optimization method, including steps of building up a first acoustic response model for a controlled area inside a car and building up a second acoustic response model for an uncontrolled area inside the car; building up a first acoustic response difference calculation model based on the first acoustic response model and the second acoustic response model; calculating optimal solution of audio parameters; and controlling each speaker to output audio signals according to corresponding optimal solution of audio parameters. Thus, the vocal area isolation is achieved, so as to provide more extreme acoustic hearing, sound field effect in the controlled area where the user is located inside the car is optimized.
