TOWARDS A REASONABLE PENALTY FOR AMPLITUDE MODULATED WIND TURBINE NOISE

Research output: Contribution to journalArticle

Abstract

Wind farm noise containing amplitude modulation (AM) is more annoying than continuous noise with the same spectral characteristics. The objective of this paper is to review existing penalty schemes that propose an adjustment to the allowable wind farm noise limit based on the presence of AM. The basis on which these penalty schemes were developed is explored and their applicability to the various types of AM such as ‘swishing’, ‘thumping’ and ‘rumbling’ is discussed. A review of standards and guidelines in Australia reveals that AM is not penalised in the majority of states, which may be putting the amenity of people living near wind farms at risk. Hence, guidelines in Australia should introduce a penalty for AM such as the one developed by Renewable UK. The Institute of Acoustics has invested considerable time and resources into developing a method of AM detection and quantification called the ‘Reference Method’, which can be used in conjunction with the Renewable UK penalty scheme. Some adjustments to both the Renewable UK penalty scheme and the ‘Reference Method’ are proposed.
