Brüel & Kjær adds a new array of microphones to the widest range of equipment for measuring acoustic holography market. This is an array of 30 microphones pentangular low cost (model 4949) with a diameter of 3.5 meters. The system has a camera in the center of the array and its arms can be oriented at 0 ° or 30 ° to the plane of acquisition. The main applications are the localization of sound sources at a distance or large areas (factories, wind turbines, trains ...).
Like other applications of acoustic holography, this array using the PULSE system and equipment acquisition. In this way the user not only has a tool designed to locate sources of noise if no access to the platform complete acoustic and vibration market.
