Analysis of Assessments of Low Frequency Noise from Wind Turbines. Calculations of Impact Range According to HN 30:2009

Darius Šaliūnas, Vitalijus Volkovas

Abstract


Since January 1, 2010, hygiene norm HN 30:2009 "Infrasound and low frequency sounds: Limit values for residential and public buildings" came into force in Lithuania. Project developers of economic activities (including developers of wind farms) face the problem how to assess correctly what infrasound and low frequency sounds levels will be met in the vicinity and how to not exceed limit values. Lithuania has no approved low frequency noise calculation method therefore the paper shortly reviews major issues of assessing low frequency noise from wind turbines, highlights its major problems, and also gives some recommendations for calculation of noise at low frequencies. Additionally, calculations of the distances from wind turbines where the   exceeding of limit values could be met are presented. Calculations show that depending on a wind turbine in a plane terrain these distances can vary from 100 m to 2 km and more.
