Silent Menace (Part 1 of 2): Wind Turbine Infrasound – What You Can’t Hear Can Hurt You
Author: Deever, Donald Allen
June 1, 2019 – Desert Report: Sierra Club California/Nevada Desert Committee Sci-fi fans remember the tagline from the Alien movie poster, which ominously declared, “In space, no one can hear you scream.” Likewise, research on the infrasound frequencies produced by industrial wind turbine blades is increasingly providing proof that what you can’t hear, can hurt you. Accordingly, it is worth noting that there is a huge difference between the auditory terms “sound” and “noise.” According to the Canadian Centre for . . .

Infrasound: Your ears “hear” it but they don’t tell your brain
Author: Salt, Alec
Presentation by Alec N. Salt, PhD, Department of Otolaryngology, Washington University School of Medicine, St. Louis, Missouri, USA, at the Symposium on Adverse Health Effects of Industrial Wind Turbines, Picton, Ontario, October 29-31, 2010. [Download a PDF of the presentation slides from the link at end of this article.] Wind turbines generate infrasound. Wind turbine infrasound is at levels that cannot be heard. Widely cited interpretations: “If you cannot hear a sound … it does not affect you.” – Leventhall G. . . .

Inaudible noise of wind turbines
Author: Ceranna, Lars; Hartmann, Gernot; and Henger, Manfred
Number of wind turbines and their size are constantly growing Wind turbines and wind farms generate strong infrasonic noise which is characterized by their blade-passing harmonics (monochromatic signals) Generated noise of wind turbines can theoretically be estimated geometrical spreading ≈ R−1 SPL ≈ rpm4 Recordings from field measurements near a single wind turbine show that the theoretical model is also valid for frequencies below a few Hz Minimum distance between an infrasound array and a wind farm can be estimated . . .
