Noise Pollution Prevention in Wind Turbines: Status and Recent Advances

The global push towards sustainability has led to increased interest in alternative power sources other than coal and fossil fuels. One of these sustainable sources is to harness energy from the wind through wind turbines. However, a significant hindrance preventing the widespread use of wind turbines is the noise they produce. This study reviews recent advances in the area of noise pollution f...

Noise Spectra from Wind Turbines

This paper presents observations of audio noise in frequency range 20-20 000 Hz from wind turbines. The observations were performed around the theoretically calculated 40 dBA noise perimeter around the wind turbine farm at Oxhult, Sweden. This paper describes a newly designed and constructed a field qualified data acquisition system to measure spectra and total noise level of sound from wind tu...

Wind Turbines: A Different Breed of Noise?

Preliminary Assessment of Noise Pollution Prevention in Wind Turbines Based on an Exergy Approach

Most existing methods for energy transformation and use are inadvertently contaminating our water supplies, releasing greenhouse gasses into the atmosphere, emitting compounds that diminish the earth's protective blanket of ozone, and depleting the earth’s crust of natural resources. As a result, scientists and engineers are increasingly pursuing sustainable technologies so that costs associate...

The Effects of Vision-Related Aspects on Noise Perception of Wind Turbines in Quiet Areas

Preserving the soundscape and geographic extension of quiet areas is a great challenge against the wide-spreading of environmental noise. The E.U. Environmental Noise Directive underlines the need to preserve quiet areas as a new aim for the management of noise in European countries. At the same time, due to their low population density, rural areas characterized by suitable wind are considered...

Low-frequency noise from large wind turbines.

As wind turbines get larger, worries have emerged that the turbine noise would move down in frequency and that the low-frequency noise would cause annoyance for the neighbors. The noise emission from 48 wind turbines with nominal electric power up to 3.6 MW is analyzed and discussed. The relative amount of low-frequency noise is higher for large turbines (2.3-3.6 MW) than for small turbines (≤ ...
