Abstract:
An error model-based multi-zone sound reproduction method includes arranging a speaker array, and setting control points for a bright zone and a dark zone. The bright zone is a zone requiring the generation of an independent sound source. The dark zone is a zone not requiring the generation of an independent sound source. The method further includes conducting probability distribution modeling on the speaker frequency response errors. The method further includes, according to the error distribution model, respectively listing expected average sound energy expressions of the bright zone and the dark zone and a frequency response consistency constraint expression of the bright zone. The method further includes calculating a time-domain impulse response filter signal of each channel according to the time-domain sound energy contrast control criterion of the frequency response consistency constraint.
