Solar power generation produces infrasound

Do wind turbines produce infrasound?

In summary, the sound signature from wind turbines is very variable and complex. However, there is ample evidence that wind turbines produce infrasound and that it couples with nearby buildings, in some cases amplifying resonant infrasound frequencies. It may also produce higher frequency sound and this is an area where more research is needed.

Is infrasound SPL higher inside a house than at a wind turbine?

In general, the infrasound SPL is lower inside the houses than it is at the wind turbine, however, just as van Kamp and van den Berg (2018) postulated, the indoor SPL is higher for certain infrasound frequencies due to resonance of the structures and different houses have different resonant frequencies.

Does wind turbine infrasound cause stress?

One of the most rigorous studies into the effects of wind turbine infrasound on people is reported in Maijala et al. (2021). They studied two groups of people living near a wind turbine farm. The first group of people, called the ‘symptomatic group’, reported symptoms of stress that were thought to be caused by wind turbine infrasound.

Do wind turbines emit infrasound and low-frequency noise?

Let’s run through them. Claim: “Wind turbines emit infrasound and low-frequency noise.” Wind turbines undoubtedly create infrasound. It is created by the movement of the blades through the air, as the blades pass the tower and, depending on the construction of the turbine, by the gearbox.

Does wind turbine infrasound cause a phobic reaction?

Wind turbine infrasound produces perceptible vibrations and audible sound in nearby buildings. Most people are unaffected by wind turbine infrasound, but some people have a phobic reaction to it. Bracing the diaphragm structures in the dwellings of affected people may solve the problem.

Are children affected by wind turbine infrasound?

Zagubién and Wolniewicz, (2020) found that children in school were not affected by wind turbine infrasound and opined that this might be because they were less likely to expect that turbine noise might be problematic. In adults, personal factors and social variables are just as likely to produce symptoms such as annoyance.
