Abstract
An area reproduction system includes a speaker array with a plurality of speakers arranged side by side, receives an input of a reproduced sound, collects an environmental sound in a non-reproduction area different from a reproduction area in which a sound beam of the reproduced sound is emitted, acquires noise included in the environmental sound and a leakage sound leaking to the non-reproduction area, generates a masking sound having a sound pressure higher than that of the leakage sound based on the frequency characteristics of the sound pressures of the noise and the leakage sound, adjusts the directivity of the masking sound to be output from each of the plurality of speakers in such a manner that the sound beam of the masking sound is emitted to the non-reproduction area while avoiding a listener, and causes each of the plurality of speakers to output the adjusted masking sound.
