Sound source exploration device and a sound source exploration method

摘要

The present invention improve the position specific to improve the accuracy of the sound source to generate a low-frequency sound. A The information processing apparatus 50 of the sound source localization device according to the present invention is based on the acoustic signals acquired position information by the position information and the microphone 11 of the grid points on the virtual screen of the microphone 11, the acoustic signal at the grid points on the virtual screen a delay signal calculation unit 53 for calculating a delay signal, the phase difference enhancement signal calculating section 54 for calculating a phase difference enhancement signal by N times the phase of two or more integer N of the calculated delay signal, the virtual screen a sound pressure level calculation unit 55 for calculating the sound pressure level at each point of the above, based on the sound pressure level at each grid point on the virtual screen, and the sound pressure map generating unit 56 for generating a sound pressure map, and the generated comprises a sound pressure map display section 57 for displaying the sound pressure map to the display device 59 are superimposed on the captured image of the object source localization picked up by the image pickup device 20, the.FIELD 6
