of 39%. In December 2010, AGL identified that under certain wind conditions tones from the wind turbines were audible at the nearest residence. Resonance dampers have since been installed to address this tonality issue with the wind turbines. Noise testing has confirmed that this permanent acoustic treatment has fixed the tonality issue. Turbines have a spread of 10 km N-S, 4 km west of
