COMPARISON BETWEEN MODELLED AND MEASURED SOUND LEVELS FOR A SOUTHERN ALBERTA WIND FARM

摘要

As an approval condition by the Alberta Utilities Commission (AUC) for a 23 wind turbine generator (WTG) expansion with substation a Comprehensive Sound Level Survey (CSL) was conducted. Three receptor locations were included, where the noise 1 impact was predicted to be within 1 dB of the nighttime (10 PM - 07 AM) threshold of 40 dBA. A CSL with a duration of 38 days was conducted. This article will summarize some of the lessons learnt.
