Bookmark or Share- Sound Barrier Penetration | Acoustic Challenges, Solutions & EffectsBreaking the sound barrier is one of the most exhilarating aspects of aerodynamics that marks a significant achievement in the field of engineering. To understand this phenomenon, it’s important to first grasp what the sound barrier actually is.
- Sound barrier - WikipediaOn 21 August 1961, a Douglas DC-8 broke the sound barrier at Mach 1.012, or 1,240 km/h (776.2 mph), while in a controlled dive through 41,088 feet (12,510 m). The purpose of the flight was to collect data on a new design of leading edge for the wing.
- What is the sound barrier and how does it work? - Physics NetworkA noise barrier (also called a soundwall, noise wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution.
- Sound barrier - New World EncyclopediaIn aerodynamics, the sound barrier usually refers to the point at which an aircraft moves from transonic to supersonic speed. The term came into use during World War II when a number of aircraft started to encounter the effects of "compressibility," a grab-bag of various aerodynamic effects.
- What is the sound barrier? - How It WorksThe sound barrier is simply the point an object exceeds the speed of sound – a speed many scientists once considered impossible. Sound is a travelling wave of pressure. A moving object pushes nearby air molecules, which push the molecules next to them, and so on.
