Infrasound From Wind Turbines Could Be ‘A Huge Threat To The Entire Biodiversity’: Doctor, by Maurice Forgeng

Turns out sounds you can’t hear may be more dangerous than those you can. They’re not good for animals, either. From Maurice Forgeng at The Epoch Times via zerohedge.com:

More than 70,000 wind turbines operate across the United States, and the U.S. government continues to approve offshore wind projects as part of its transition toward clean energy.

When wind turbines rotate, however, they generate not only electricity but also infrasound.

For Dr. Ursula Bellut-Staeck, this development represents “a huge problem for all forms of organisms,” including humans. The medical doctor and scientific author has been studying the health effects of infrasound for several years. She has been looking into infrasound as a stressor on the cellular level since 2015 and published a paper in 2023 on how infrasound affects microcirculation and endothelial cells.

Inaudible but Impactful

Infrasound is defined as a sound wave with a frequency of less than 20 hertz (Hz). The lower the frequency of the sound, the greater its wavelength and the harder it is to shield from it. Infrasound can penetrate walls, people, and animals.

“With ever larger wind turbines, the frequencies are getting lower and lower. This makes infrasound more problematic and dangerous,” Dr. Bellut-Staeck told The Epoch Times.

Today’s wind turbines reach frequencies as low as 0.25 Hz. The wavelength of this frequency is just under 0.86 miles.

Infrasound has another special feature. Humans cannot usually hear frequencies below 16 Hz, which marks the so-called lower hearing threshold. In other words, we cannot hear many of the sounds emitted by wind turbines. However, we may feel them in our bodies as humming or rumbling, as with a loudspeaker. The lower the frequency, the higher the sound pressure level (i.e., the volume) must be to feel or hear it.
