Acoustic Camera Array Star48 AC Pro48 Channel System for Outdoor Measurements The microphone array Star48 is our largest preconfigured array and particularly suitable for outdoor measurements of large objects. The lightweight folding aluminum body of the array ensures a stable and safe setup by just one person. The array has 48 interference-resistant microphone channels. The recommended measurement distance ranges from four meters up to several hundered meters, depending on the spectral content of the measured acoustic signal and ambient conditions. Large objects can be measured and analyzed via time and frequency domain acoustic beamforming using the same methods as our smaller microphone arrays. Analysis can be performed quickly using NoiseImage software. ■ Easy handling and accurate microphone positioning ■ Distinct array pattern aids in troubleshooting even with non-ideal focus measurements ■ Slim aluminum array body ■ Environmental noise control ■ Pass-by measurements of vehicles ■ Wind tunnel measurements ■ Applications with low to mid-range acoustic frequency The Star48 features a Baumer VCXG-25C camera to provide ideal reference images for acoustic measurement tasks.
