PROBLEM TO BE SOLVED: To provide an acoustic reproduction system capable of allowing a listener to easily understand the positional relationship between a listener's present hearing position and a sweet spot.SOLUTION: A listener M operates a portable terminal 10 to measure each of: a setup position of an L-channel speaker 27; a setup position of an R-channel speaker 28; and a lister's hearing position. A sound-reproduction system 20 sets up and controls a sound field on the basis of the positional information. At the same time, an optimum hearing region calculation unit 210 calculates a sweet spot (optimum hearing region) by simulating the level of the sound variation in each position over the acoustic space on the basis of the sound field setup information. Then, the portable terminal 10 displays the information indicating the present listener's hearing position acquired periodically or automatically and the information indicating the sweet spot calculated by the optimum hearing region calculation unit 210 on the screen of a display input unit 12. |
