» 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    http://www.borderlands.com/archives/arch/gavreaus.htm

» In-Flight Rotorcraft Acoustics Program (IRAP)    NASA's aeronautics research will reduce noise to make helicopters and tiltrotors more acceptable to the public. The objective of IRAP is to acquire rotorcraft noise data in flight for comparison to wind tunnel data.    http://halfdome.arc.nasa.gov/research/IRAP-intro.html
