Acoustic Camera Array Fibonacci72 AC Pro 72 Channel System for Beamforming and Holography – Far Field and Near Field The Fibonacci array is the first Acoustic Camera that allows near field as well as far field measurements. The aluminum structure of the array guarantees the maximum possible acoustic transparency as well as a precise microphone alignment. Due to the spiral microphone arrangement, beamforming achieves the highest possible spatial resolution and the best possible map dynamics. In combination with the NoiseImage analysis soft ware, the specially optimized microphone arrangement allows the user to use the Fibonacci array for holography (SONAH and HELS) and standard beamforming analyses. The array comes standard with both an integrated Intel® RealSenseTM depth camera, which has full HD resolution and the ability to record depth information, and a Baumer camera. In this combination, you get excellent measurement results in near-field and far-field applications. BENEFITS Easy handling and accurate microphone positioning Beamforming and holography methods can be used with the same hardware Minimizes reflections, sound pressure doubling effects on the surface, and imposed resonance effects due to the acoustically transparent array design APPLICATIONS Environmental noise control Wind tunnel measurements Acoustic leakage detection Low-frequency sound sources in the near field High-frequency sound sources in the far field Fibonacci array measurement set up
