PROBLEM TO BE SOLVED: To represent a two-dimensional distribution of sound pressure as an image for a sound component generated by vibration inside a measuring object included in a sound emitted from the measuring object.SOLUTION: A two-dimensional distribution of correlation between sound pressure and vibration is calculated on the basis of a two-dimensional distribution of sound pressure of a sound emitted from a measuring object 100 and vibration inside the measuring object 100 detected by a vibration sensor 3. Among images in which a sound pressure distribution is represented as an image, an image in which drawing density of an area where correlation having less than a predetermined value is detected is the minimum density is created; and an image obtained by overlapping the created image on an image of the measuring object 100 photographed by a camera 1 is created and displayed on a display device 9 as a sound pressure distribution image c1. |
