PROBLEM TO BE SOLVED: To change the magnitude of acoustic parameters intuitively.SOLUTION: The acoustic device includes a display for displaying a graphic indicating the magnitude of acoustic parameters on a display screen 15a, and a touch panel is provided in the display screen 15a. The parameter changing section of the acoustic device changes the magnitude of acoustic parameters, in response to the pinch-in and pinch-out operations for the touch panel. A display control section changes the graphic depending on the magnitude of parameters after change. In the acoustic device, the magnitude of acoustic parameters can be changed by the pinch-in and pinch-out operations for the touch panel, and the magnitude after change can be confirmed in the graphic. Consequently, a user can change the magnitude of acoustic parameters intuitively. |
