Wind turbine noise affects dream sleep and perceived sleep restoration

Wind turbine noise (WTN) influences people’s perception of the restorative effects of sleep, and also has a small but significant effect on dream sleep, otherwise known as REM (rapid eye movement) sleep, a study at the University of Gothenburg, Sweden, shows. A night of WTN resulted in delayed and shortened REM sleep.

Knowledge of how sleep is affected by WTN has been limited to date. Research involving physiological study of its impact using polysomnography, the top-ranking method of sleep recording, is lacking.

Studies carried out in the Sound Environment Laboratory at the Department of Occupational and Environmental Medicine in Gothenburg are adding new knowledge in the field. Polysomnography involves using electrodes attached to the head and chest to record brain activity, eye movement, heart rate, etc. during sleep.

Of the 50 participants in the new study, 24 had been living within one kilometer of one or more wind turbines for at least one year. The other 26, the reference group, did not live near wind turbines.

Kerstin Persson Waye, Professor of Environmental Medicine at Sahlgrenska Academy, University of Gothenburg, is the corresponding author in the study, published in the journal Sleep.

“We wanted to find out whether people exposed to noise from wind turbines over time become more sensitive or more habituated to WTN, so that their sleep may be affected differently than someone who doesn’t live near any turbines,” she says.

The participants spent three nights in the Sound Environment Laboratory, one for acclimatization and then, in a random order, one quiet night and one with four separate periods of WTN. The sounds that were used were modeled based on outdoor measurements from several wind turbines, and was filtered to correspond with the sound insulation of a typical Swedish wooden house. Exposure was further modeled, to correspond to sleeping with a closed window and window ajar respectively.

The sounds were chosen to represent relatively unfavorable conditions, with a slightly higher average outdoor noise level than is currently permitted in Sweden. This level corresponded, however, with a low indoor noise level — below the levels at which sleep had previously been found to be affected by, for example, traffic noise.

During the night with WTN, according to the physiological measures, the participants spent an average of 11.1 minutes less in REM sleep, which they entered 16.8 minutes later, than during the quiet night. The proportion of time they spent in REM sleep was 18.8% for the night with WTN, compared with 20.6% for the quiet night — a small but statistically significant difference that, moreover, was independent from habituation to WTN.

There were no statistically significant differences in other sleep parameters, such as number of awakenings, total sleep time, time in deeper (non-REM) sleep stages or fragmentation of deep sleep, and heart rate. However, rhythmic sound variations appeared to disturb sleep, especially with closed windows.

Besides the physiologically based measurements, participants filled out a questionnaire on their sleep quality and how tired or rested they felt. Both groups reported that they slept worse during nights with WTN.

The study gave no indication of the habituation effect or increased sensitivity in the participants exposed to wind turbines in their home environment. However, the group that lived close to wind turbines reported worse sleep overall, even during the quiet night.

“Sleep disturbance, a negative health effect according to the World Health Organization (WHO), can in itself contribute to chronic diseases. However, we can’t draw conclusions from this study on long-term health impact. Further studies should, if possible, investigate sleep in people’s home environments and include longer exposure time,” Kerstin Persson Waye concludes.

Wind Turbines Can Cause Sickness

Wind Turbines Can Cause Sickness, Say Public Health Officials

WHO-HD CHANNEL 13 NEWS|August 12, 2019

WINTERSET, Iowa — The Madison County Board of Public Health is going on record to say that there are legitimate negative health effects caused by wind turbines.

Board Chair Dr. Kevin de Regnier said the board identified two concerns after a review of scientific literature and months of hearings and meetings with residents and MidAmerican Energy.

The two health concerns identified are:

  1. “Flicker” caused by the sun reflecting off turbine blades creates a strobe effect that can cause headaches and nausea.
  2. “Infrasound” is a soundwave just below what the ear can actually detect. It is created by the turbines disturbing wind flow.  It, too, can cause headaches and nausea.

“Resolved that the Madison County Board of Health determines that there is the potential for negative health affects associated with commercial wind turbines and that current setbacks are inadequate to protect the public health,” said Madison County Public Health in a statement to Channel 13.

The board recommends that any future wind turbine projects be 1.5 miles from any residence…..

K2 Wind “farm” ordered to reduce Noise

k2 wind turbine T330

CTV London|May 27, 2019

The K2 Wind farm in Huron County needs to make some changes, the Ministry of Environment has ordered.

The wind farm operators must fix noise issues with their turbines, after noise testing found some of the turbines were “out of compliance.”

The order is vindication for Mike and Carla Stachura, who have been complaining about noisy turbines near their Dungannon area home for more than four years.

K2 Wind, which consists of 140 turbines, must now fix the noise issues either by limiting the hours the turbines operate, de-rating the turbines to reduce sound levels, or change when they use the turbines in relation to wind speed or direction.

They have until June 14 to have a plan to fix the noise problems. They also have the ability to appeal the provincial order.

The owners of the K2 Wind Farm, Axium Infrastructure, say they take “their responsibility to operate within the established guidelines of the Renewable Energy Approval permit very seriously, and we will continue to work closely with the ministry to resolve any operational issues that may arise.”

K2 Wind Out of Compliance

K2 wind turbines

K2 Wind  under an issued provincial order by Ontario is to immediately comply with noise performance limits for operations of its industrial wind turbine installation.

[210] Mr. James, an expert called by the Appellants, provided a number of critiques of the noise assessment models used to predict sound levels produced by the Project. Mr.James agrees with the proposition that was put before him that the Approval Holder’s noise assessment reports comply with the MOE Noise Guidelines. He states, however, that there are serious issues with the Noise Guidelines themselves such that, by complying with the Guidelines, the actual level noise levels emanating from the Project will be underestimated.

Wind turbine infrasound as a weapon

“Industrial wind turbine infrasound is not the best weapon, but it is a weapon. This German video documents the harmful effects of d the infrasound produced by industrial-sized wind turbines. The dangers of infrasound have been known since the 1980s when the U.S. military heavily invested in infrasound (below 20 Hz) as a weapon. It looked like it had great promise, according to Col. John B. Alexander who was involved in weaponizing it.. The military gave up on infrasound as its effects on people were too random: some potential targets were seriously debilitated; others not so much. This video presents various studies by acoustical engineers and other scientists showing infrasound’s affect on the ear, the heart, the brain and other organs.”
