The existing exposure-response relationships describing the association between wind turbine sound level and noise annoyance concern turbine sizes of 0.15-3.0 MW. The main purpose of this study was to determine a relationship concerning turbines with nominal power of 3-5 MW. A cross-sectional survey was conducted around three wind power areas in Finland. The survey involved all households within a 2 km distance from the nearest turbine. Altogether, 429 households out of 753 participated. The households were exposed to wind turbine noise having sound levels within 26.7-44.2 dB LAeq. Standard prediction methods were applied to determine the sound level, LAeq, in each participant’s yard. The measured sound level agreed well with the predicted sound level. The exposure-response relationship was derived between LAeq outdoors and the indoor noise annoyance. The relationship was in rather good agreement with two previous studies involving much smaller turbines (0.15-1.5 MW) under 40 dB LAeq. The Community Tolerance Level (CTL), CTL20 = 50 dB, was 3 dB lower than for two previous studies. Above 40 dB, a small number of participants prevented a reliable comparison to previous studies.

Abstract – Current technology uses wind turbines’ blade aerodynamics to convert wind energy to electricity. This process generates significant low-frequency noise that reportedly results in residents’ sleep disruptions, among other annoyance symptoms. However, the existence and the importance of wind farms’ health effects on a population scale remain unknown. Exploiting over 800 utility-scale wind turbine installation events in the United States from 2001 to 2013, I show robust evidence that wind farms lead to significant increases in suicide. I explore three indirect tests of the role of low-frequency noise exposure. First, the suicide effect concentrates among individuals who are vulnerable to noise-induced illnesses, such as the elderly. Second, the suicide effect is driven by days when wind blows in directions that would raise residents’ exposure to low-frequency noise radiation. Third, data from a large-scale health survey suggest increased sleep insufficiency as new turbines began operating. These findings point to the value of noise abatement in future wind technology innovations.

A Report for the Legislative Energy Commission, 10/19/2017 —
Many Minnesotans report sleep deprivation, migraine headache, vertigo and ringing in the ears after large wind turbines are installed near their homes. Some have left their homes.
MN Department of Health identified low-frequency noise as the most likely cause and confirms that the health of some Minnesotans is being harmed by wind turbines.
Setback distance between a turbine and a home is based on wind turbine noise. State agencies concur that they understand so little about wind turbine noise they cannot even enter into rulemaking on wind turbine noise.
Minnesotans who are harmed have no recourse.
European countries more experienced with wind turbines than Minnesota have setbacks that are 10 times the height of the turbine to the blade tip at its highest point (5000 feet for large modern wind turbines).
- Site permit setback distance from homes is based on “noise” even though the State knows so little about turbine noise they cannot enter into rulemaking on the topic.
- Minnesotans’ homes are inside the turbine Safety Evacuation Zone.
- What studies does the PUC have in front of it and how did they respond?
- Citizens whose health and peaceful enjoyment of their private property are harmed by wind turbines have no recourse.
- PUC approved research of LFN by the University of Minnesota that fails to study LFN in homes and the health of people living next to turbines.
- Audible Noise – agreement that 40 dB(A) should be the limit, but no good measurement protocol to determine if it is met.
- Low-Frequency Noise is the problem. Measurable – but no standards.
- What should the Minnesota Legislature adopt for a siting standard?

State of New York Supreme Court, County of Wyoming—
33. Upon information and belief, Defendant Invenergy created and owns a wind energy operation, including wind turbines on property located within 800-1500 feet from the properties owned by Plaintiffs.
34. Upon the construction of and operation of the· wind turbines, Defendant has destroyed Plaintiffs’ rural viewshed from their property.
35. Upon the construction of and operation of the wind turbines, Defendant has caused constant noise, vibrations and flicker to enter Plaintiffs’ property, significantly impacting the health and wellbeing of the Plaintiffs and causing them to become sick, sore, lame and disabled.
36. Upon the construction of and operation of the wind turbines, Defendant has caused constant noise and vibrations significantly diminishing the value of Plaintiffs’ property and home.
37. Upon information and belief, Defendant’s wind turbines have violated, on a regular basis, town noise ordinances that restrict the noise levels to 50 decibels.
38. Moreover, Defendant’s operation of such wind turbines caused noise pollution, vibrations, and flicker to occur, creating a nuisance and interfering with Plaintiffs’ exclusive possessory interest in their property, and causing Plaintiffs’ quality of life to be significantly diminished.
39. In spite of being informed of the nuisance condition created by the Defendant, the Defendant has refused to either abate the nuisance or otherwise engage in any mitigating measures, intentionally continuing the nuisance that they have created, causing a significant diminishment of the Plaintiffs’ use and enjoyment of their property, quality of life, health, value of Plaintiffs’ property and economic wellbeing.
