Acoustics is a branch of physics that studies sound, namely mechanical waves in gases, liquids, and solids. A scientist that works in the field of acoustics is an acoustician. The application of acoustics in technology is called acoustical engineering. There is often much overlap and interaction between the interests of acousticians and acoustical engineers.
...*coustics is characterized by its reliance on combinations of physical principles drawn from other sources; and that the primary task of modern physical acoustics is to effect a fusion of the principles normally adhering to other sciences into a coherent basis for understanding, measuring, controlling, and using the whole gamut of vibrational phenomena in any material.Origins in Acoustics.

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.
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.
Meta Description: [ A key part of NASA's aeronautics research is reducing noise to make helicopters and tiltrotors more acceptable to the public. The objective of the In-Flight Rotorcraft Acoustics Program (IRAP) is to acquire rotorcraft noise data in flight for comparison to wind tunnel data. The type of noise of c... ]

Sara - 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.
