Noise guidelines for wind projects are absolutely useless.
Regardless, the so-called responsible authorities use them as permissible levels on which they approve an application for a permit to build a wind project.
Guidelines are based on irrelevant parameters that cannot protect adjacent residents. They are the basis for a government licence to damage residents.
There has been more than enough hard information placed before responsible authorities over many years to prove health damage from wind turbines, but that information has been effectively and wilfully ignored, helped of course by the members of the wind industry cabal .
However all great rorts finally come to their end; in this case the World Health Organisation on October 13, 2018 proclaimed that health problems are associated with wind turbines.
This is a major step forward, and is now a platform for more detailed technical research on pressure wave emissions from turbines and the impacts on adjacent residents. The technical explanation is well covered by the Waubra Foundation, the best of Australia’s independent acousticians, and international researchers.
DeFrock demands that the physical and mental abuse of wind project neighbours cease, and that the projects existing, and new, be rendered safe and guaranteed so.
So let us now set out safe guidelines. In doing so we need to do away with the current pretense that they were a guide only. Planning authorities treat them as law. These guidelines must be rewritten, rendered safe and nominated as rules that the industry must meet, and relevant authorities enforce.
An explanation of the technology of wind turbines and their emissions is presented in the Waubra Foundation’s website as a key document. It was written in 2013 and is still largely correct in 2018. It may be updated by the Foundation from time to time.
DeFrock is not interested in participation in the arguments about dangerous anthropomorphic global warming nor its successor Climate Change, as others have explored these quite different matters and are continuing to do so. However DeFrock notes that the most assertive alarmists seem to be the technically ignorant metropolitan population. A group of people that do not know what they do not know.
However this post is about how to make wind turbines safe. If described as open air energy factories it is natural to focus on safety of surrounding neighbours. So let us get started.
Sound in units of decibels (dB) is a measure of the loudness of the airborne pressure pulses (sound). Ground-borne vibrations also are generated, which surely enhance the discomfort that, in this case, are caused by wind turbines. The other major characteristic is the frequency of the sound emitted.
Guidelines, project layouts and testing are, however, based on dBA, which is a weighted expression of dB over a selected frequency range.
dBA actually has no relevance to the sound of the turbines. nor to the impact on neighbours.
Yes, we know, they are already built and causing extraordinary harm to many. But can we demand they be made safe now? Of course we can. Having been awarded an unsafe planning permit does not entitle anyone to continue to inflict serious high level pain to anyone. The only problem is who pays the piper: the industry or the responsible entities? Think of an aeroplane with a licence to fly, but develops a technical problem; grounded until the problem is fixed.
These projects must be rendered safe by whatever changes are necessary, e.g., shutting down turbines that are too close to homes, buying affected properties for proper and fair compensation, or closing the project down.
Defrock demands that whatever it takes, these projects must be made safe. Perhaps subsidies should be withheld while the projects are unsafe, and only restored when the project is determined to be safe.
Projects in Construction
Projects in construction should be placed on hold whilst sound contours are reworked in dB inside homes and the project layout altered where necessary. Safety guarantees must be given before work is recommenced.
Proposed New Projects
Noise forecasts in dB inside homes must be predicted, and safe distances and layouts must be presented to permit applications. Safety guarantees must be given.
In all cases allowances must be made for amplitude modulation of sound waves which is particular to wind turbine geometry and to other matters such as turbine positioning and layout.
