Literature from Rome Wind Turbine Noise Conference, April 2011Dr. Shepherd Critique of Current Noise Modeling• “…it should be noted than globally there has been a systemicfailure in the prediction of noise levels and sound characteristicsemanating from wind turbine installations.” (Shepherd, Witness Statement beforeEnvironmental Review Tribunal, 15.)• “…there is substantive international evidence showing that theseerrors are due to a lack of adequate methodology. Concern has,arguably, been nurtured by the lack of acknowledgementregarding the limitation of current methods.” (Shepherd, Witness Statement, 15.)• “…suffice to say that any noise contours based on existingmodels need to be extensively critiqued.” (Shepherd, Witness Statement, 15.)• “Indeed, drawing on my experiences in New Zealand, thedifferences between predicted noise levels presented duringsubmission periods and actual noise levels measured in the postcommissioningperiod leads me to have little faith in the currentmethodology.” (Shepherd, Witness Statement, 15.)
