  • Wind turbine noise estimates should include cumulative impacts (40-50 dB(A) isopleths) of all wind turbines.
  • Isopleths for dB(C) — dB(A) greater than 10 dB should also be determined to evaluate the low frequency noise component.
  • Potential impacts from shadow flicker and turbine visibility should be evaluated.
  • Any noise criteria beyond current state standards used for placement of wind turbines should reflect priorities and attitudes of the community.
