Title (EN) POSITION DETERMINATION OF SOUND SOURCES
(FR) DÉTERMINATION DE POSITION DE SOURCES SONORES
Abstract: front page image
(EN)The invention relates to a Microphone arrangement, having at least two pressure gradient transducers (1, 2), each with a diaphragm, with each pressure gradient transducer (1, 2) having a first sound inlet opening (1a, 2a), which leads to the front of the diaphragm, and a second sound inlet opening (1b, 2b) which leads to the back of the diaphragm, and in which the directional characteristic of each pressure gradient transducer (1, 2) has a direction of maximum sensitivity, the main direction, and in which the main directions (1c, 2c) of the pressure gradient transducers (1, 2) are inclined relative to each other. The invention is characterized in that the microphone arrangement has at least one pressure transducer (5) with the acoustic centers (101, 201, 501) of the pressure gradient transducers (1, 2) and the pressure transducer (5) lying within an imaginary sphere (O) whose radius (R) corresponds to the double of the largest dimension (D) of the diaphragm of a transducer (1, 2, 5).
(FR)L'invention concerne un microphone ayant au moins deux transducteurs de gradient de pression (1, 2), chacun avec un diaphragme. Chaque transducteur de gradient de pression (1, 2) possède une admission de son (1a, 2a) menant à l'avant du diaphragme, et une seconde admission de son (1b, 2b) menant à l'arrière du diaphragme, et la caractéristique directionnelle de chaque transducteur de gradient de pression (1, 2) présente une direction de sensibilité maximale, la direction principale, et les directions principales (1c, 2c) des transducteurs de gradient de pression (1, 2) sont inclinées les unes par rapport aux autres. L'invention se caractérise en ce que le microphone a au moins un transducteur de pression (5) avec les centres acoustiques (101, 201, 501) des transducteurs de gradient de pression (1, 2) et les transducteurs de pression (5) se situant dans une sphère imaginaire (O) dont le rayon (R) correspond au double de la dimension la plus grande (D) du diaphragme d'un transducteur (1, 2, 5).
