“Director of the [British] Noise Abatement Society reported that at a research centre at
Marseille, France, an infrasound generator had been built which generated waves at 7
Hz. He said that when the machine was tested, people in range were sick for hours.
The machine could cause dizziness, nervous fatigue and ‘seasickness’ and even death
up to 8 km away (Associated Press, Leicester, England, 9 September 1972).”
