Abstract
Noise impacts are considered to be one of the most concerning environmental impacts due to the installation and operation of industrial wind turbine. This study presents the investigation of some aspects in wind turbine noise generation and propagation through wind tunnel testing of a 580 mm diameter small wind turbine. Such understanding is desired in an attempt to reduce the impact of wind turbine noise on human health. The results of this experimentation indicate the major existence of low frequency noise (between 50 Hz to 400 Hz) at slower wind and lower RPM, while higher frequency noise (between 1,600 Hz to 6,400 Hz) is produced at higher wind speeds and higher RPM. Different near-field measurements along the blade span also show that noise generation is more significant at the blade tip.
