Boundary Microphone for wind turbine noise

The Boundary-Layer Microphone GFM 920 is a measuring microphone especially designed to record sound emissions at Wind Power Stations according to IEC/EN 61400-11. Additionally, the GFM 920 is suitable for determining emission-relevant sound power levels in open spaces, e.g. measurements at power stations, construction sites, filtration and cooling plants among others.

Due to the near-ground positioning of the GFM 920, unwanted influences on the measurement results from ground reflections are avoided.
