• Gavreau's Infrasound Weapons Dr. Gavreau and his staff made a observation which, not only interrupted their work, but became their major research theme. They periodically experienced a disconcerting nausea which flooded the research facility. Low frequency sound (7 Hz) could resonate and cause nausea.
