PROBLEMS WITH WIND ENERGY, WIND TUBINS

How to Measure Low-Frequency Noise from Wind Turbines in Homes: A Field-Ready Protocol

TL;DR: This post gives you a complete, practical plan to (1) record indoor low-frequency/infrasound (0.5–200 Hz) and structure-borne vibration, (2) quantify amplitude modulation (the “thump”), and (3) link exposure to sleep and physiology using an ABAB curtailment design. It is designed to stand up in peer review and regulatory settings.

1) Why measure inside homes?

People don’t live at the property line—they sleep in bedrooms. Very-low-frequency pressure and building vibration can couple indoors, especially at night. Measuring indoors captures what the body actually experiences and lets you correlate exposure with sleep disruption, heart-rate variability (HRV), blood pressure, and symptom relief when turbines are curtailed or residents sleep elsewhere.

2) Study design at a glance

• Design: Case-crossover + curtailment (ABABAB nights). Randomized shutdown/feather windows (e.g., 22:30–02:30) vs matched control nights.
• Blinding: Residents are not told which nights are curtailed to minimize expectation/nocebo effects.
• Add-on: A short away-from-home phase (3–5 nights) tests symptom reversal while the house stays instrumented.

3) Equipment & specs checklist

Domain	What you need	Key specs
Acoustics (pressure)	2× Class-1 SLMs or equivalent front-ends, + 1–2 infrasound microbarometers	24-bit; Z/A/C/G-weighting; 1/3-oct bands down to ~0.5 Hz; WAV ≥512 Hz; noise floor ≤17 dB(A); proper windscreens/porous hoses
Vibration	3× DC-coupled MEMS accelerometers + 24-bit logger	Bandwidth 0–100 Hz; noise density ≤50 µg/√Hz; mount on slab, interior wall, and bed-frame
Meteorology	10 m mast ultrasonic anemometer + barometer/temp/RH	1 Hz logging; sync to acoustics
SCADA	Operator feed: rotor RPM, blade pitch, yaw, on/off/curtailment	Time-synced to sensors (drift < ±1 s/week)
Sleep/Physiology	Actigraphy watches; overnight HRV straps; automated BP; optional salivary cortisol	1-min epochs for sleep; RMSSD for HRV; morning/evening BP

4) Sensor placement

• Indoors (primary): Bedroom mic at head height; accelerometers on bed-frame and slab (plus one interior wall).
• Outdoors (reference): Mic at 1.5–2 m AGL with secondary windscreen (façade or open yard).
• Secondary room: Living-area mic to confirm whole-house coupling.
• Time sync: GPS or NTP; verify drift weekly.

5) 8–10 week protocol

1. Phase A – Baseline (2 weeks): Continuous logging during normal turbine operation.
2. Phase B – Curtailment (6 weeks): ABABAB nights with 2–3 randomized curtailments/week; match control nights by wind and weather.
3. Optional Phase C – Away: Participants sleep away from home 3–5 nights while home sensors keep logging.

6) Acoustic & vibration metrics

• Levels: LAeq, LCeq, LZeq, LGeq (ISO 7196) with 1/3-octaves from 0.5–200 Hz (indoor & outdoor).
• Amplitude Modulation (AM): IOA Reference Method (10-s windows) + cycle-synchronous analysis keyed to rotor RPM.
• Low-frequency guidance check: Compare indoor bands to DIN 45680 night-time criteria.
• Vibration: RMS/peak acceleration (0–80 Hz), crest factor, pressure–vibration coherence, and “thump” event counts/hour.

7) Health & sleep endpoints

• Primary: Sleep efficiency, actigraphy awakenings/WASO; overnight HRV (RMSSD); morning BP.
• Secondary: EMA prompts (headache, dizziness, ear pressure, nausea, anxiety 0–10); PSQI, Epworth, WHO-5.
• Event buttons: Residents can mark felt “thumps” to anchor exposure snippets.

8) Analysis blueprint (pre-register)

1. Exposure contrast check: Confirm curtailment nights reduce indoor LGeq and AM indices (paired tests/mixed models).
2. Within-person models: Case-crossover or mixed effects: Outcome ~ AM (or LGeq; 1–20 Hz bands) + temperature + wind + random subject.
3. Lag structure: 1, 5, and 15-min lags for arousals/HRV dips vs AM peaks.
4. Dose–response: DIN 45680 exceedance vs symptom probability.
5. Sensitivity: Away-from-home nights and unplanned outages as mechanistic checks.

9) Reporting standards & QA/QC

• Standards hooks: Reference methods aligned with IEC 61400-11/-11-2 (acoustics near turbines), IOA AM method, ISO 7196 (G-weighting), DIN 45680 (indoor low-frequency).
• QA/QC: Field calibration (pre/post), mic self-noise checks, windscreen documentation, 10-s analysis windows, and retention of raw WAV + SCADA.
• Transparency: Preregister protocol; publish code and anonymized datasets where possible.

10) Team, timeline, practical tips

• Minimum team: 1 acoustics lead, 1 field tech, 1 data analyst, 1 clinician/IRB liaison.
• Timeline: Setup 1–2 days → Logging 8–10 weeks → Analysis/report 2–4 weeks.
• Operator coordination: Secure randomized curtailment windows in advance. If not possible, exploit outages and tighten matching.
• Blinding matters: Don’t alert residents about curtailment nights.
• What “good evidence” looks like: Indoor LGeq/AM drop during curtailment and sleep/HRV improve on the same nights.

The LACK of REAL Science education TODAY is alarming and can destroy us.

It amazes me how lacking in organic chemistry and in life science modern people are. But then again, this is shown in DNA studies of our ancestors who were much more intelligent. Small minded people will do what is necessary to maintain income and for no other reasons. They will make up all sorts of junk "science" to solicit money from politicians. For instance, you cannot get a grant to lower energy usage in homes by 70% to 80% (30% use of energy) and take people off the grid.

 I know. I tried this. There is no money to feed the political system by taking people off grid and lowering energy usage and NOT reducing even one aspect of opulent lifestyle. Automatic washing machines, dryers, refrigerators, computers, huge TV's, sound systems. The way to reduce energy usage is easy to do.


Political ideologies run rampant, and all of them are about greed. If you want to start a new industry (like wind turbines that are now proven to be so destructive to life on the planet and the environment) , you must destroy the old industry, because you do not own that industry, and never will. It is much more lucrative to destroy the competition with lies than to actually come up with something better.
So posting scientific lies as if they are true is the new form of corporate greedy warfare. There is no real study showing that increased CO2 is "bad". It is actually extremely good for life on earth to have more. In fact we are LOW on CO2 right now.
Let me explain to you how the earth maintains temperate climates.
It is the OZONE layer producing the FILTER of radiation that keeps gamma rays, high levels of UV and harmful radiation from the planet surface. Ozone is an oxygen molecule that has been changed by UV radiation from the sun, into O3 molecule. O3 is the blue color we get from the sun filtered by OZONE and other natural gasses in the atmosphere.

In order to have more ozone, bluer sky, and better harmful radiation filtering as it was before, we need MORE CO2.
This has been known about for a long time, but not one, so called, climate scientist, ever discusses this as the real issue. There are no grants for production of more CO2 and increased vegetation, as a solution to any environmental issues.
All of the fossil fuels are CARBON based matter that was in the form of CO2 on top of the earth before it was buried. It is natural as it comes. Fossil fuels are not some foreign matter from aliens in outer space designed to kill us as is the common myth of stupid people today.
Fossil fuels are natural to the earth and not harmful to the environment even when they are burned without all the "regulations". The regulations come from burning in areas with poor air movements or in areas with too much burning in a small country. And not burning with enough oxygen to burn up the "unburned hydrocarbons". Burning (clean high temp burning) all the carbons and making pure CO2 is a way to recover the life on earth, to grow more food, to have more oxygen and a more temperate weather pattern.
The problem is JUST THE OPPOSITE of this junk pseudo climate science, not based on anything but greed and greedy politicians.
More CO2 = More Plant (vegetation) Health;  More Vegetation health = More Oxygen;  More Oxygen = More Ozone Layer; More Ozone layer = better environmental conditions on earth, more temperate climate, more even temperature, better health and less skin cancer.
Ozone is made from oxygen hit by UV radiation from the sun, and it is a temporary molecule that needs to constantly be produced. More oxygen from having more CO2 means more healthy vegetation.
The CO2 levels reached an all time low in the recent times. It is now barely 400 PPM, and it needs to be over 1000 PPM to 2000 for healthy plant (and human) life and lower and more even temperatures on earth. Healthy plant life means better life on the planet.
We got rid of Freon in aerosol cans to stop destroying the ozone layer. Now we need more CO2 and more plants with more oxygen to restore the ozone layer to much safer levels for life on earth. The rise in skin cancer is directly caused by lack of ozone filtration of harmful UV rays from the sun.
The most rapid rise of skin cancer comes from lack of OZONE, caused by lack of CO2, and vegetation making the oxygen needed for OZONE.
If you want to completely destroy all life on earth, then lower the CO2 even more. If it gets below 150 PPM there will be no life on earth at all, no plankton, no food, no vegetation at all.
CO2, Carbon (life giving) dioxide, is two atoms of oxygen and one of Carbon. It is not a poison. It is GOOD for all humans and animals to have more oxygen and more ozone caused by the rise of CO2.
We are "CARBON BASED LIFE FORM". Remove the CO2 and we cease to exist.

The Religion of "environmentalism"

There is only ONE good thing about "environmentalism".  It shows that in people's hearts, somewhere deep is a desire for life to continue. The problem is "environmentalism" is harmful to the environment and is proven in every fact we find in objective evidence to do so.  God bless the environmentalists, but if you really want to know what is at the foundation of this "movement" it is the same garbage as we find in all of these types of movements.  GREED.

When I live in Holland for some time, I found out that my computer types underwater.  That it was some sort of delusion because the "god" of pseudoscience, Al Gore, told me I would be underwater.  People who are on the Envoreligioism band wagon completely forget that ALL of Al's predictions never came to pass. 
My friends in Florida told me that their TV's  and computers and everything works just find "under water".   
How is it possible for people to actually believe these rich greedy "environmentalists" when everything they have said to date is a lie.  Not one of Al Gore's predictions have shown up or even slightly. 

100% of the "environmentalism" is not backed by any scientific facts or any laws of natural physics. CO2 is natural.  CO2 is good for life.  It is part of the life on our planet and all the "fossil fuels" are not some foreign toxic wast from Mars or whatever these idiots try to sell. It is organic materials buried in the ground and if it wasn't it would not burn. Originally it was life on top of the earth. 

You can burn all the fossil fuel (correctly cleanly as we do now) and all it does is feed the vegetation ecosystem, causes more rain to feed these plants and ultimately puts far more oxygen in the air. More CO2 ultimately results in more oxygen.  More oxygen means more, ozone in the upper atmosphere,  filtering more of harmful electromagnetic radiation from the sun and causing more temperate climates on the entire earth.   

It is BS from people with a profit and power agenda.
The media fanatics,  work hard to sell this crap because it makes a huge pile of cash for them, causes a lot of new "environmental" businesses which they "magically" own by the way.

For instance Wind Turbines are made from toxic chemicals, destroy the landscape, are environmentally bad because they clear the land of trees, kills birds and ruins bird habitat, and they are inefficient. The are so UGLY that I can't imagine how someone can be that blind. They cause harmful low frequency sounds that destroy human health in those who live near these damned things. 

When I drive across the USA over the years, at least 100 times the beauty of our country is being ruined by these UGLY things and 90% of the time they are not turning even in full wind. That tells me it is just a fraud on the public.
If you want to be environmentally friendly with these things you would put them where they cannot destroy life.
