Human perception of
sound from wind turbines Pedersen, Eja; Forssén, Jens; and Persson Waye, Kerstin
The level of background noise at distances of a kilometre or more from wind turbines makes measuring the effect of
sound from wind turbines on people at such distances complicated.
Wind turbine noise is a reported cause of these effects; however, some commentators suggest
sound from wind turbines does not pose a risk of any adverse health effect in humans.
The truth, of course, is that
the sound from wind turbines is rarely audible from distances greater than 3 km and infrasound near wind turbines is no greater than elsewhere.
There is no reason to believe, based on the levels and frequencies of the sounds and the panel's experience with sound exposures in occupational settings, that
the sounds from wind turbines could plausibly have direct adverse health consequences.

Some small
wind turbines produce as little as 35 decibels (dB) of
sound when heard
from a distance of only ten feet away.
The infrasound
from wind turbines is at very low intensity (the Vic Health study showed it was not above background levels), while the
sound from NSW fire appliances would be hundreds or thousands of times more intense.
Better than reading pages like this, if you want to know how much
sound wind turbines produce go and visit a
wind farm, listen
from various distances, make up your own mind.
I find it interesting that while there have been many complaints
from wind power opponents about how much noise
wind turbines make, this is the only recording that I have come across of a
sound that could be truly annoying.
I have visited multiple
wind farms, and stood directly beneath operating
turbines from 150kw to 2.2 MW in size, and there is nothing emanating
from them that can be discerned above background
sound.
[8] In other words, direct causation of the reported «annoyance» effects
from the impulsive reproduced
sound energy identical to «
wind turbine noise» was clearly established.
How - to guide to criteria for siting
wind turbines to prevent health risks
from sound Kamperman, George; and James, Richard
We have seen no reports of the Ministry opposing the presence of refrigerators in the region, suggesting they appreciate that
sounds emitted
from wind turbines and refrigerators are quite different.
Infrasound
from wind turbines is sufficiently correlated to the A-weighted
sound emissions to allow an A-weighted model to be used to predict how much infrasound is present in homes.
To reflect the ministry's conservative approach to dealing with noise emissions
from wind turbines and to support the adoption of the 2013 CSA standard, three amendments are being proposed to the definition of «
sound power level» in the REA Regulation to provide clarity:
«With all the available evidence
from around the world about the effects of Low Frequency and Infrasound
from industrial
wind turbines, it amazes me that the alarms are not
sounding earlier and stronger.»
Certainly any
sound from the
wind farm would not be a problem, no - one would hear the
turbines because of the traffic noise.
The best thing you can do to learn the facts on the
sound levels
from wind turbines is to visit a
wind farm yourself.
An expert panel review of «
Wind Turbine Sound and Health Effects» conducted for the American
Wind Energy Association and the Canadian
Wind Energy Association was available
from the American
Wind Energy Association (but the original link is no longer working).

There is some evidence to suggest that audible noise
from wind turbines at elevated
sound pressure levels may be associated with disturbed sleep and negative emotions.

Research into the computer modeling and other methods used to determine the layout of
wind turbine developments, including the distance
from nearby residences, is at the same time showing that the output of the models may not accurately predict
sound propagation.

Thorough primary scientific research (not simply studies of exiting research) into human and animal heath and annoyance due to
sound and infrasound
from wind turbines could be carried out, and it should be done on behalf of government, the
wind industry, and the general public so that the research can be seen to be unbiased.
If a person sees a
wind turbine (as I do) as graceful, elegant, an optimistic symbol of a cleaner and better future and finds the
sounds that
turbines make pleasant and restful (as I do), they are very unlikely to develop any ill - effects
from being near
turbines.
The minimum distance that a
wind turbine should be
from an occupied house is partly a matter of opinion and, since the
sound level varies depending on topography and the direction of the
wind, is very difficult to place a definite figure on.
Another plaintiff, a local Justice of the Peace, «has difficulty sleeping, can not have his windows open (and) can not enjoy the
sound of nature, due to loud noise
from wind turbines.»
Some, or even many, of those who claim that
turbines cause sickness would have us believe that there is something coming
from wind turbines, other than the
sounds that everyone who visits a
wind farm can hear, and beyond the low levels of infrasound that acousticians can detect, that makes people sick; and yet they seem unable to tell us what that thing is.
«Bubble curtains» are also being used to protect marine wildlife
