Management and control of noise pollution in wind turbines are important to integrate wind turbines in building and urban areas. A scaled model of a horizontal-co-axial wind turbine was designed, built and tested in the wind tunnel of University of Technology Sydney (UTS) and its characteristics and aerodynamic-noise emissions were analyzed. The noise reduction capability of the horizontal-twin-shaft wind turbines was compared with wind turbines with the conical entry nozzle (stator), duct-shroud-envelop and vertical shafts. Air velocity, shaft rpm, electric-power generation, noise frequency and amplitude were measured. It was found that up to 15% reduction in the amplitude (dB) of noise emisit from twin shaft wind turbine compared to the single shaft bench mark turbine. The noise analysis performed as a result of these experiments may be used in the design and selection of a building integrated horizontal axis wind turbine for applications at UTS buildings.
