PURPOSE:To pursue efficient acoustic design and proposing type business by realizing sound field reproduction having actual presence based on the simulation result of a sound characteristic in a room. CONSTITUTION:A virtually experiencing device for sound environment 1 is provided with a analyzing section 1 for sound environment, a sound field reproducing section 2, and an output section 3. The analyzing section 1 for sound environment divides a space to be analyzed into several planes, performs calculation of reflection tone using reflection coefficient and a morphological coefficient of each divided plane, and calculates received sound quantity time series information in which quantity of a sound produced from the prescribed sound source reaches the prescribed receiving point. In the sound field reproducing section 2, an impulse response calculating section converts the received sound quantity time series information into impulse response data. A reproduced sound generating section generates a reproduced sound by convoluting impulse response to a dry source based on a position information of a man of experience inputted from an associated virtual reality device and outputs a sound to a headphone. |
