Abstract:
Noise assessment of wind turbines through calculations is based on sound power levels measured according to e.g. IEC 61400-11. With larger wind turbines and distances some of the calculation models give erroneous results. Noise propagation over water is different from propagation over land. For that reason it is important be able to make valid noise assessments for offshore wind farms. A suggestion for an offshore measurement method is described and a survey of models for noise propagation offshore has been made.

Abstract in Danish:
Vindmøllers støjbelastning fastlægges gennem støjberegninger udfra lydeffektniveauer bestemt efter f.eks. IEC 61400-11. For store vindmøller og store afstande giver nogle af beregningsmodellerne forkerte resultater. Lydudbredelse over vand er anderledes end over land. Derfor er det vigtigt, at kunne fastlægge støjbelastningen fra offshore mølleparker på en sikker og entydig måde. Der er lavet et oplæg til en offshore målemetode, samt en gennemgang af modeller for lydudbredelse offshore.
