As always these articles are written to uplift and inform, and not to upset. I would like to produce a little information about wind turbines.
These wind turbines produce a low frequency and audible noise while in motion and this noise has a pounding, thumping character and can be clearly heard at night.
This pulsing character of high-level noise has been proven to disturb sleep, thus coining the name nightmare noises and is responsible for a number of health problems.
Many residents who have wind turbines less than one-and-a-half miles from their home are adversely affected by the noise of these turbines as they are easily within the decibel levels to disturb sleep.
These neighbours of wind turbines describe the nightmare noises as bothersome and a sleep disturbance causing decreased performance, increase blood pressure, cardiac arrhythmia and change in breathing patterns.
Wind turbines also create moving visual disturbances especially early and late in the day when long shadows of moving blades sweep rhythmically through that neighbourhood; and people with seizure disorders become susceptible to seizures being triggered by the strobes effect of seeing the sun through the moving blades.
We all know that noise has an adverse effect and the most strongly affected areas are memory, attention, problem solving and reading just to name a few. People who are able to tune out this wind turbine noise suffered from an increased level of stress and these adverse effects are larger in children with lower school achievement.
To be easily understood, noise levels should be 35 decibels or less and these turbines produce a higher noise level (greater than that of your vacuum cleaner or washing machine), especially at night, due to the fact that noise travels farther due to the coolness of the air at ground level and the steady stream of wind at the level of the turbine hubs.
It must be said that this article is in no way against the erecting of wind turbines; however, it is strongly against the erecting of such turbines close to populated areas if less than one-and-a-half to two miles (to be safe) in circumference from any populated area or even further in a mountainous area simply because they have been proven to be a serious health risk. Thank you.
