| Abstract | Measurements of the noise emitted by the Eole wind turbine, a 4-megawatt vertical axis wind turbine (VAWT) located at Cap Chat in the Province of Quebec, Canada, were carried out in October 1989. The object of the measurements was to furnish information on the effect of large VAWT on the noise environment of the surrounding area and on the noise generation and propagation from it.
The procedure used is presented with a description of the measurement sites, the instruments, and the calibration and data reduction procedures. The background noise levels measured before and after the turbine installation at different measurement sites were compared to estimate the effect of Eole on the environment. The noise levels measured at equidistant distances upwind, downwind, and perpendicular to the wind are also reported.
It was determined that, at the turbine site, the Eole wind turbine operation increases the background noise levels by about 8 dBA but does not increase the background noise levels beyond a 300 m radius from the turbine. |
