Abstract:
An area reproduction method includes converting a sound pressure distribution at each frequency of a reproduced sound from a sound pressure distribution in a frequency domain into a sound pressure distribution in a spatial frequency domain. The reproduced sound is realized on a control line, including a reproduction line in which sound waves emitted from a speaker array including a plurality of speakers arranged intensify with each other, and a non-reproduction line in which the sound waves weaken with each other. The method includes determining a spatial frequency for use in adjustment of the reproduced sound, in the sound pressure distribution in the spatial frequency domain, based on a positional relationship between the speaker array and the control line, and adjusting a sound pressure of the reproduced sound, which is to be output by each of the plurality of speakers using the determined spatial frequency.
