SOUND BARRIER Meaning and
Definition
-
The term "sound barrier" refers to a phenomenon in physics known as the "sonic barrier" or "Mach 1." It is a theoretical point at which an object moving through a medium, such as air or water, reaches or exceeds the speed of sound. When an object travels at subsonic speeds (below the speed of sound), the sound waves it produces can travel ahead of it. However, once the object approaches the speed of sound, the pressure waves generated cannot escape fast enough, causing them to merge into a single shock wave. This combined wave creates a sudden and dramatic increase in pressure, resulting in a sonic boom.
The concept of the sound barrier is often associated with aviation, particularly supersonic flight. Breaking the sound barrier was thought to be impossible until the 1940s when aircraft and technology advanced to a level capable of accomplishing such feats. The achievement of supersonic flight allowed for increased speed and efficiency in aerospace engineering, and it opened the door for the development of faster military jets and high-speed transportation.
Overcoming the sound barrier presents challenges in terms of propulsion, aerodynamics, and structural integrity, as tremendous forces are exerted on the aircraft. Moreover, the sound barrier is not a fixed point but rather influenced by various environmental factors, such as air temperature and density. Despite these challenges, breaking the sound barrier has marked significant progress in the field of aviation and has expanded our understanding of aerodynamics and the limitations of flight.

Etymology of SOUND BARRIER
The term "sound barrier" was coined to describe a historical challenge in aviation. It refers to the phenomenon of intense aerodynamic drag experienced by an aircraft as it approaches the speed of sound. The word "sound" is derived from the Late Latin word "sonus", meaning "a noise or sound". The term "barrier" in this context implies an obstacle or limitation that must be overcome. The concept of a sound barrier became more widely recognized in the 1940s and 1950s when aircraft engineers and pilots were striving to break the speed of sound.
