 Sara - http://www.sara.com/ wave creation, propagation, reception and understanding are at the core of our business. Sound at frequencies below that which can be heard to light at frequencies above that which can be seen barely begin to span the range of experience and understanding that unify our four technology areas. |
 Gavreau's Infrasound Weapons - http://www.borderlands.com/archives/arch/gavreaus.htm 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. |
 In-Flight Rotorcraft Acoustics Program (IRAP) - http://halfdome.arc.nasa.gov/research/IRAP-intro.html 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. |
