Study of Wind Turbine Noise Propagation Characteristics Considering Geographical Features

Wind Turbine Noise Propagation Modelling: An Unsteady Approach

Wind turbine sound generation and propagation phenomena are inherently time dependent, hence tools that incorporate the dynamic nature of these two issues are needed for accurate modelling. In this paper, we investigate the sound propagation from a wind turbine by considering the effects of unsteady flow around it and time dependent source characteristics. For the acoustics modelling we employ ...

Wind Turbine Noise : Theoretical and Experimental Study

Wind turbine acoustical noise is a relevant element to be considered and studied because of the growing interest in renewable energies. The environmental impact of these structures in the surrounding areas is deeply investigated, especially on the acoustical and the landscape point of view. This paper is mainly devoted to the integration between analytical, experimental and software analysis on...

Wind Turbine Noise Issues

Wind turbine noise.

The evidence for adequate sleep as a prerequisite for human health, particularly child health, is overwhelming. Governments have recently paidmuch attention to the effects of environmental noise on sleep duration and quality, and to how to reduce such noise. However, governments have also imposed noise from industrial wind turbines on large swathes of peaceful countryside. The impact of road, r...

Wind Farm Layout Optimization Considering Energy Generation and Noise Propagation

Wind farm design deals with the optimal placement of turbines in a wind farm. Past studies have focused on energymaximization, cost-minimization or revenue-maximization objectives. As land is more extensively exploited for onshore wind farms, wind farms are more likely to be in close proximity with human dwellings. Therefore governments, developers, and landowners have to be aware of wind farms...
