Abstract: To visualize a sound image which can be received by a person with hearing sensation from a sound field by calculating a horizontal direction feeling and a depth direction feeling of the sound image.SOLUTION: Music content is reproduced in a living room, signals recorded with two microphones for a few minutes are segmented in each short time, and horizontal direction feeling information is calculated from time difference and sound volume difference and depth direction feeling information is calculated from a cross-correlation coefficient. In such a case, weighting by an average sound pressure level and frequency characteristic along human auditory characteristics is performed. Conversion from the cross-correlation coefficient into depth direction distance uses a sound image distance coefficient acquired by changing distance between a microphone and a speaker by using a test sound in advance to calculate a measurement and cross-correlation coefficient. Many pieces of sound image information obtained by processing signals over a few minutes in each short time is visualized as a coordinate by using an orthogonal coordinate system or a polar coordinate system. Further, a frequency in each point of the coordinate is calculated, a three-dimensional representation by the sound image information and the frequency is performed, and the visualization of a sound field including a central position of the sound image is achieved.SELECTED DRAWING: Figure 5
