Tip o’ the hat to Ocotillo Wind Turbine Destruction

Mass CEC 2 Types Of Wind Turbine Noise
Massachusetts Clean Energy Center Aware of Two Types Of Wind Turbine Noise in 2005
Folks, Prior to the installation of Falmouth Wind I there was an attempt to install wind turbines in Mattapoisett starting in 2005. The Massachusetts Clean Energy Center in 2005 was well aware of two distinct types of noise. One was regulatory noise and the other was called “human annoyance”.
Today we know the human annoyance noise is called many other names such as low frequency, infra sound etc. There is no getting around the fact that they were aware of the different types of noise. No matter how you cut it there are at least two types of noise from commercial wind turbines.
The simple fact is this has been known as far back as 1987.
The state of Massachusetts has declared war on fossil fuels and has a renewable energy agenda of 2000 megawatts of renewable energy by the year 2020. The war and agenda is taking residents health and property rights with no compensation to reach that goal with commercial wind turbines.
The Falmouth residents & taxpayers have to ask why the Mattapoisett wind study in 2005 referenced two distinct types of noise and then the reference was left out of any of the Falmouth wind studies prior to the installation of Wind I.
It’s obvious that the Town of Mattapoisett rejected the wind turbines and the negative reference to two distinct types of noise was simply dropped from the Falmouth wind studies.
Here is the Mattapoisett reference material :
The material clearly describes two distinct types of noise.
Regulatory & Human Annoyance
On page 14 of the Marion ,Mattapoisett and Rochester wind test study- Noise
Noise considerations generally take two forms, state regulatory compliance and nuisance levels at nearby residences:
A. ”Regulatory compliance”: Massachusetts state regulations do not allow a rise of 10 dB or greater above background levels at a property boundary (Massachusetts Air Pollution Control Regulations, Regulation 310 CMR 7.10). This sound level is very unlikely to be a reached incase at the sites we examined.
B.”Human annoyance”: Aside from Massachusetts regulations, residences must also be taken into consideration. Any eventual turbine would be sited such that it would be inaudible or minimally audible at the nearest residences. At this stage, to check for “fatal flaws,” a rule of thumb can be used: to minimize possible noise impacts,site wind turbines at least three times the blade tip height from residences. Distances from mixed-use areas may be somewhat shorter.
SIMPLE QUESTION IS THERE MORE THAN ONE TYPE OF NOISE FROM THESE TURBINES ? WHY WAS THIS REFERENCE DROPPED FROM THE FALMOUTH WIND STUDIES
