![]() 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.
