The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound.

Dec 24, 2024 · Sound barrier, sharp rise in aerodynamic drag that occurs as an aircraft approaches the speed of sound and that was formerly an obstacle to supersonic flight. If an aircraft flies at somewhat less than sonic speed, the pressure waves (sound waves) it creates outspeed their sources and spread out.

Dec 20, 2024 · A 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.

Jan 29, 2025 · A sleek white aircraft has become the first independently developed jet to break the sound barrier. The XB-1 aircraft accelerated to Mach 1.05 within about 11 minutes of taking off Tuesday.

May 21, 2024 · The sound barrier is a concept developed in the early 20th century, when many scientists believed that the drag on aircraft caused by approaching the speed of sound made it impossible for any aircraft to reach or exceed the speed of sound without being destroyed.

Sound barrier is a phenomenon where sound waves in the air get packed densely ahead of a moving thing (such an aircraft) and form a highly pressurized area there. Sound is vibration in the air, and it goes as sound waves.

Jan 7, 2025 · The meaning of SOUND BARRIER is a sudden large increase in aerodynamic drag that occurs as the speed of an aircraft approaches the speed of sound.

Feb 16, 2017 · The next barrier for air travel looks hyper: hypersonics, a regime that begins at Mach 5, five times the speed of sound, or 3,300 miles per hour (5,311 kph) at altitude. Langley’s work with hypersonics was spurred in part in the 1940s by the post-war discovery of a German Mach 5 wind tunnel.
