Abstract

PURPOSE: To make it possible to easily and accurately obtain the correspondences in position and shape between a sound image reproduced and a body to be measured by arranging one or more reference speakers in a plane which is in parallel with a hologram plane and which includes the body.
CONSTITUTION: The sound waves emitted from a body 1 to be measured and a reference speaker 3 are recorded by microphones 5 and 7 as the data in a hologram plane 6. The data thus recorded are reproduced as a sound image in a plane, which corresponds to a plane 2 including the body 1, by the analysis using the interference between the signal waves and reference waves. Since, at this time, the sound image of the reference speaker 3 is reproduced, the position of such a point A on the sound image as has shape characteristics of the body 1 can be obtained by dividing the position of the sound image of the speaker 3 so that the correspondence in position and shape between the body and the sound image can be determined.
