The Ontario Ministry of the Environment (MOE) has implemented a simple procedure to assess the noise impact of a wind farm, consisting of a group of wind turbines. The process identifies the locations of the wind turbines within the wind farm as well as all the sensitive receptors within an influence zone of 1 km. It evaluates the noise levels at all identified receptor locations by using a standardized propagation model such as ISO-9613. The procedure also allows the potential masking effect of the prevailing wind noise. Meteorological data, wind speed and direction are obtained as one-hour averages from the weather station near the wind farm. The wind speeds at 10 m high are converted to a hub-height of 80 m and then reconverted back to the 10 m high wind speeds. The results show that local conditions do not follow any set patterns and there can be substantial variations in evaluated noise levels.
