Vladimir Gavreau

From Wikipedia, the free encyclopedia

Vladimir Gavreau( born in Russia as Vladimir Gavronsky) was a French scientist making experiments on the biological effects of the infrasound.

His interest in infrasonic waves first came about in his lab during the 1960s where he and his lab assistants experienced pain in the ear drums and shaking lab equipment, but no audible sound was picked up on his microphones. He concluded it was infrasound and soon got to work preparing tests in the labs. One of his experiments was an infrasonic whistle.
