Résumé

Cet article décrit les résultats de test d'une méthode afin de mesurer la réponse directionnelle d'une sonde d'intensité vectorielle d'hydrophones. La sonde hydrophonique d'intensité en 3 dimensions de la compagnie NORDCO a été conçue afin de capturer simultanément les trois composantes du vecteur intensité d’un champ acoustique. La sonde d’intensité aux hydrophones en phase nécessite de positionner avec précision les éléments receveurs afin d'obtenir une réponse en temps réel. Pour calculer la réponse directionnelle de la sonde d'intensité, les composantes vectorelles x, y et z d’un champ acoustique généré par une source stationnaire ont été mesurées en faisant tourner la sonde d'intensité autour de l'axe z. Les courbes d’intensité acoustique ainsi obtenues ont montré que l'on obtenait les variations en cosines espérées avec un écart très précis de 90° entre les minima des composantes en x et en y.
