![]() ![]() The noise predicting modelling approach was as follows: the simplest model, positioning a single point source at the top of the hub, can be used to predict sound levels for a typical wind turbine if receptors are located 250 m from the hub a-weighted sound power levels of a wind turbine at cut-in and cut-off wind speed should be used in the models 20 by 20 or 50 by 50 meter terrain parameters are suitable for large wind farm modeling and ISO 9613-2 methods are recommended to predict wind farm noise with various metrological inputs based on local conditions. ![]() AUC, ISO and IEC criteria requirements for the meteorological input with Cadna/A for wind farm noise were also discussed. This paper presented an analytical comparison of the 3 models used for a typical wind turbine with a hub tower containing 3 propeller blades, a drive-train and top-mounted generator, as well as a representative wind farm, using Cadna/A. ![]() These include a disk of point sources a ring of point sources located at the tip of each blade and a point source located at the top of the wind turbine tower hub. ![]() The developer of Cadna/A, recommended the following 3 models for simulating wind turbine noise. DataKustik GmbH developed the Computer Aided Noise Abatement (Cadna/A) modeling software for calculating noise propagation to meet accepted protocols and international standards such as CONCAWE and ISO 9613 standards. All wind turbine arrays must undergo a noise impact assessment. ![]()
