The present invention relates to an error model-based multi-area sound reproduction method, comprising: arranging a speaker array and setting control points of a bright area and a dark area, the bright area being an area requiring the generation of an independent sound source, and the dark area being all areas not requiring the generation of an independent sound source; conducting probability distribution modeling on a speaker frequency response error; according to the error distribution model, respectively listing expected average sound energy expressions of the bright area and the dark area and a frequency response compliance constraint expression of the bright area; and calculating a time-domain impulse response filter signal of each channel according to the time-domain sound energy comparison and control criterion of the frequency response compliance constraint. Compared to conventional methods, the present invention effectively reduces contrast performance degradation caused by speaker frequency response error, and improves robustness and reliability of the device. |
