Title (EN) SOUND SOURCE PROBING SYSTEM
(FR) SYSTEME DE SONDAGE D"UNE SOURCE SONORE
Abstract: front page image
(EN)In order to specify and display the source of noise in a factory, or the like, accurately even in the outdoors, two pairs of microphones (M1, M3; M2, M4) are disposed, respectively, on the X axis and Y axis while spaced apart by a distance L. Direction of a sound source is estimated based on the difference of arriving time of output signals from the pair of microphones (M1, M3) and the difference of arriving time of output signals from the pair of microphones (M2, M4). Furthermore, the image in the vicinity of an estimated sound source is picked up by means of a camera (11) and the estimated position of sound source is indicated on an image displayed on the display (23) of a personal computer (20).
(FR)Afin de spécifier et d"afficher la source d"un bruit dans une usine ou similaire, de façon précise même à l"extérieur, on dispose deux paires de microphones (M1, M3; M2, M4) respectivement sur l"axe X et l"axe Y, en les espaçant par une distance L. La direction de la source sonore est estimée sur la base de la différence du moment d"arrivée des signaux de sortie provenant de la paire de microphones (M1, M3) et de la différence du moment d"arrivée des signaux de sortie provenant de la paire de microphones (M2, M4). En outre, l"image à proximité de la source sonore estimée est captée par une caméra (11) et la position estimée de la source sonore est indiquée sur une image affichée par l"écran (23) d"un ordinateur personnel (20).
