Accuracy of Model Predictions and the Effects of Atmospheric Stability on Wind Turbine Noise at the Maple Ridge Wind Power Facility, Lowville, NY
Author: Schneider, Clifford
The main objective of this study was to measure the noise levels at two sites within Atlantic Renewable Energy Corporation’s Maple Ridge Wind Power Project located in Lewis County, New York, and compare actual levels with the model predictions that were available in the preconstruction Draft Environmental Impact Statement (DEIS). The second objective was to examine atmospheric stability at Maple Ridge. Atmospheric stability was identified as a significant problem at a wind farm on the Dutch-German border. . . .

H. Noise.
1. Audible Sound Limit.
a. No Wind Turbine or group of turbines shall be located so as to cause an exceedance of the pre-construction/operation background sound levels by more than 5 dBA or dBC. The background sound levels shall be the L90 dB sound descriptor (both A and C weighting) measured during a pre-construction noise study during the quietest time of evening or night. Measurements shall be for ten (10) minutes or more. L90 results are valid when L10 results . . .

The sound of high winds: the effect of atmospheric stability on wind turbine sound and microphone noise

IV.3 Wind turbine noise perception
There is a distinct audible difference between the night and daytime wind turbine sound at some distance from the turbines. On a summer’s day in a moderate or even strong wind the turbines may only be heard within a few hundred meters and one might wonder why residents should complain of the sound produced by the wind farm. However, in quiet nights the . . .

Rev. 1.0, July 27, 2008
Industrial scale wind turbines are a familiar part of the landscape in Europe, U.K., and other parts of the world. In the U.S., however, similar industrial-scale wind energy developments are just beginning operation. The presence of industrial wind projects will increase dramatically over the next few years . . .

Environmental Noise Guidelines: Wind Farms
Author: Southern Australia Environment Protection Authority
Wind farms need specific guidelines because wind turbines have unique noise generating characteristics and the environments surrounding wind farm sites usually have low ambient noise. …
2 NOISE CRITERIA
The general approach in setting noise criteria for new developments is to require compliance with a base noise level.
This base noise level is typically 5 dB(A) lower than the level considered to reflect the amenity of the receiving environment. Designing new developments at a lower level accounts for the cumulative effect of noise from . . .

Amplitude Modulation of Wind Turbine Noise
Author: Bowdler, Dick
A Review of the Evidence
“Conclusions: It seems probable that there are two distinct mechanisms in operation to create amplitude modulation. The first is swish which is a function of the observer’s position relative to one turbine. The second is thump which is due to turbine blades passing through uneven air velocities as they rotate. In the second case the uneven air may be due to interaction of other turbines, excessive wind shear or topography. These two . . .

Micrositing
Author: Nordex
Choosing the type of wind turbine (WTG) and its exact position are very important parts of the planning work of a wind park. This process is called micrositing.
During micrositing many aspects have to be regarded:
wind conditions (statistic data concerning wind speed and wind direction)
building requirements (e.g. distances to residences)
ownership structure of the area
accessibility (existing roads)
influence of the WTG on the environment (e.g. shadow flickering, noise emission)
distances between the individual turbines in a . . .
