Abstract
This paper describes the three-dimensional simulation and measurement of sound pressure distribution generated by 120ch plane speaker array and evaluates simulation. In the simulation, 120ch plane speaker array can generate a high sound pressure area, however such high sound pressure area is not measured. To actual measurement the three dimensional high sound pressure area, the simulation can be evaluated. The simulation is evaluated by using the coefficient of correlation. A value of the coefficient of correlation can calculate a similarity of simulation value and measurement value quantitatively. As a result, the effectiveness of simulation is confirmed.
