The acoustic camera with the special wind turbine microphone array suits perfect with its big diameter of 500 cm for very low frequency sound sources. The 40 microphones are making sound visible and are localizing noise exactly from 50 Hz. The optimized microphone distribution guarantees a perfect sound source localization and a high dynamic range. Although the system has a diameter of 500 cm dismounted it can be convoyed in a car. Setup time is about 30 min. Typical applications are wind power plants, industrial facilities and environmental measurement.
