Acoustic Camera Array Evo AC Pro Mobile System for Wind Tunnel Applications The mobile array Evo was developed specifically for use in aeroacoustic applications, namely wind tunnel testing. The array’s foldable construction simplifies handling, transport and storage. The back frame is conveniently used as a storage area for the data recorder to ensure high mobility and compactness of the entire measurement system. Ground anchor points ensure a high repeatability and accuracy. This array is available with 96, 120, 144 or 168 channels. The perfect microphone positions for your application are determined in a complex opimization process, so the microphone distribution ensures the highest acoustic dynamic range and sound localization accuracy. In addition, the central positioning of the optical camera provides the best possible spatial resolution for perfect reference images. BENEFITS Easy handling and storage due to foldable construction Easy to set up Complete mobile measurement system to measure vehicles from different positions Wind tunnel measurements Pass-by measurements of vehicles Leakage detection
