There is an intense debate between proponents and opponents of wind turbine projects on the subject of health effects from LFN attributable to modern wind turbines. Opponents, using mainly early 1970's reports from obsolete-design downwind-turbine models, declare excess LFN to exist and to be a suspect cause of adverse health effects. Proponents point to the fact that there is no credible evidence showing LFN from wind turbines to have any adverse health effects. Hessler Associates has been a technical consultant on more than 60 wind projects with the primary duty of drafting Noise Assessment Analysis for project developers. We, and I might add most opponents of wind projects, are certainly not qualified as experts in the subject of health effects from LFN. In our capacity, the LFN debate is addressed by referencing studies performed by qualified scientists in the field. However, while not health experts, we can apply engineering measurements, logic and common sense to form an opinion on the subject as described in this note.
