PROBLEM TO BE SOLVED: To apply an acoustic effect optimum for each room space to an audience in the case of sound field control in indoor space such as the inside of a hall. SOLUTION: When the number of input systems from sound collecting means 102a and 102b for picking up the sounds of a sound source is defined as N and the number of output systems to speakers 106a-106d for discharging the sounds to indoor space is defined as N, N×M pieces of sound field control means 104 are provided corresponding to each combination of respective input systems and respective output systems. Besides, acoustic characteristic data are found by simulating or measuring the indoor space, sound field control data are generated by arbitrarily editing these acoustic characteristic data, these sound field control data are programmed in the sound field control means 104 and the sound field control means 104 generate the output of speakers reflected with these sound field control data. By reflecting the characteristics of an electric loudspeaker system with the sound field control data, the architectural acoustic effect in indoor space is electrically changed or emphasized. |
