PURPOSE:To simulate and experience a sound field in a design stage by performing conversion corresponding to acoustic characteristics in plural directions of the periphery of a sound reception point and generating a simulated acoustic signal, and applying simulation acoustic signals to speakers provided corresponding to the plural directions. CONSTITUTION:A simulation converting means 17 converts the acoustic signal 32 from an acoustic signal source 16 according to the acoustic characteristics in the respective directions D1 - D3 to generate the simulation acoustic signals 34 corresponding to the directions D1 - D3. Further, the speakers 22 are provided in the sound field 10 corresponding to the directions D1 - D3 of the sound field 1. Then when the simulation acoustic signals 34 are applied to the speakers 22, the speakers 22 in the simulated sound field 10 receive sounds similar to the sounds in the directions D1 - D3 in the sound field 1 although an evaluating person 7 in the simulated sound field 10 is not in a sound field to be evaluated actually. Consequently, the sound environment at the sound reception point 5 in the sound field 1 can be simulated and experienced. |
