Acoustic Camera — 80 or 120 channel microphone array for various interior measurement scenarios This spherical 80 or 120 channel microphone array is primarily designed for applications in enclosed spaces. The omnidirectional characteristics of the array make it perfect for 3D applications, for example in room acoustics. In combination with our cutting-edge software NoiseImage we offer unique 3D functionality. The 120 channel array can be operated on a mcdRec data recorder, the 80 channel array connects to the mobile gt-432 data recorder too. Depending on a signal’s spectral composition, the recommended measurement distance varies between 0.5 and 25 meters. Longer ranges are possible for measurements in considerably higher frequency ranges. The wiring of the microphones is enclosed in and protected by the array body which guarantees the best possible acoustic transparency to measure accurate sound levels. The array design is optimized to provide the highest spatial resolution as well as map dynamic, possible given the number of microphones used. Additionally, the array design effectively minimizes partial reflections, sound pressure doubling effects on the surface, and resonance effects between the measured object and the array. Furthermore, the sphere geometry minimizes aliasing effects. As this microphone array acts omnidirectional, the beamforming results are normally mapped on a scanned 3D point cloud or 3D CAD model of the measurement object, to be imported in the NoiseImage software.
