PROBLEM TO BE SOLVED: To visually recognize both sound pressure distribution and a phase distribution at the same time in an acoustic space. SOLUTION: The display control device causes a display to display an image which shows the sound pressure distribution and the phase distribution of sound of an indicated frequency component as a display object, among sounds emitted in the acoustic space, and the display control device is caused to implement the following processing while changing a phase of the display object. A complex sound pressure data indicating distribution of complex sound pressure of the sound of the frequency component in the acoustic space is obtained, and a same phase face where the phase component of the complex sound pressure, which is indicated by the complex sound pressure data, matches the phase of the display object, is obtained, and while a display mode of each section of the same phase face is controlled according to an absolute value of the complex sound pressure of each section, it is displayed on the display device.
