Evaluation of noise levels of two micro-wind turbines using a randomised experiment

Abstract

One of the more contentious environmental concerns of wind turbines is the wind turbine noise. This study assesses the noise impacts of two microwind turbines on the environment by comparing the noise generated by these turbines to traditionally accepted surrounding sounds. The sound level data was collected using a randomised experiment and fitted using a general linear model (GLM). The GLM was used to determine the relationship between the sound level generated at a given site to the time of day, the wind speed, the wind direction and a fixed predetermined distance from the sound source.
