A specific procedure for wind turbine noise assessment is required in the framework of the National Law on environmental noise revision. The procedure was developed in 2013 by the Italian environmental protection agencies in order to estimate the noise produced by a wind farm at the receivers. The method does not require the farm shut-down to achieve its goal relying on a long term measurement of noise and weather data and a subsequent computational analysis. Several steps are mandatory in order to evaluate the effectiveness and uncertainty of this procedure: further focused measurement campaigns in different environmental conditions, a numerical evaluation of the uncertainty and sensitivity of the input parameters, the validation on virtual and real scenarios. Some preliminary results of these steps are presented in this paper, focusing on the implementation of a computational model used for the validation on simulated scenarios. A better understanding of the influence of various background noise and wind turbine emission on the procedure results is earned this way.

Abstract
A specific procedure for wind turbine noise assessment is required in the framework of the National Law on environmental noise revision. The procedure was developed in 2013 by the Italian environmental protection agencies in order to estimate the noise produced by a wind farm at the receivers. The method does not require the farm shut-down to achieve its goal relying on a long term measurement of noise and weather data and a subsequent computational analysis. Several steps are mandatory in order to evaluate the effectiveness and uncertainty of this procedure: further focused measurement campaigns in different environmental conditions, a numerical evaluation of the uncertainty and sensitivity of the input parameters, the validation on virtual and real scenarios. Some preliminary results of these steps are presented in this paper, focusing on the implementation of a computational model used for the validation on simulated scenarios. A better understanding of the influence of various background noise and wind turbine emission on the procedure results is earned this way.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
