A paper published 11/25/13 in Health Psychology adds to a growing body of research indicating that perceived impacts from wind turbines are psychogenic.
"Results: During exposure to audible windfarm sound and infrasound, symptoms and mood were strongly influenced by the type of expectations. Negative expectation participants experienced a significant increase in symptoms and a significant deterioration in mood, while positive expectation participants reported a significant decrease in symptoms and a significant improvement in mood. Conclusion: The study demonstrates that expectations can influence symptom and mood reports in both positive and negative directions"
