What Is Another Word For The Sound Barrier

Sound Barrier

Sound travels at different speeds depending on the medium it is traveling through. In air, which is the most common medium, sound travels at a speed of approximately 343 meters per second. At this speed, sound waves can create a shock wave that is commonly known as the sound barrier.

Breaking The Sound Barrier

Breaking The Sound Barrier

Breaking the sound barrier is when an object travels faster than the speed of sound. This was first achieved by Chuck Yeager in 1947 when he flew the Bell X-1 aircraft at a speed of Mach 1.06 (1,299 km/h or 807 mph).

The term ‘sound barrier’ is often used to describe the point at which an object reaches the speed of sound. However, this is not entirely accurate as sound is not actually a physical barrier that can be broken.

What Is Another Word For The Sound Barrier?

Another Word For Sound Barrier

The sound barrier is also commonly referred to as the sonic barrier or the sonic boom. The term ‘sonic’ is derived from the Latin word ‘sonus’, which means sound.

The sonic boom is the sound that is produced when an object breaks the sound barrier. It is a loud, explosive noise that can be heard for miles around. The sound is caused by the shock waves that are created by the object as it moves through the air at supersonic speeds.

The Science Behind The Sound Barrier

Sound Wave

To understand the science behind the sound barrier, it is important to understand how sound waves behave. Sound waves are a type of longitudinal wave, which means that they travel in the same direction as the energy they carry.

When an object is traveling at subsonic speeds, the sound waves it produces can move out in all directions. However, as the object approaches the speed of sound, the sound waves begin to bunch up in front of the object, creating a shock wave.

The Consequences Of Breaking The Sound Barrier

Sonic Boom

Breaking the sound barrier can have significant consequences for both the object and the surrounding environment. The most noticeable consequence is the sonic boom, which can cause damage to buildings and other structures.

The sonic boom can also be extremely loud, which can be harmful to human hearing. In addition, the shock waves created by breaking the sound barrier can cause turbulence, which can be dangerous for aircraft and other vehicles.

Uses Of The Sound Barrier

Uses Of The Sound Barrier

The sound barrier has several practical applications, particularly in aviation and engineering. In aviation, the sound barrier is used to design and build supersonic aircraft that are capable of traveling faster than the speed of sound.

In engineering, the sound barrier is used to design and build noise barriers that help to reduce the amount of noise pollution in urban areas. These barriers can be made from a variety of materials, including concrete, metal, and plastic.


In conclusion, the sound barrier is an important concept in physics and engineering. While it is commonly associated with the breaking of the sound barrier, it has several practical applications in aviation, engineering, and environmental science.

Understanding the science behind the sound barrier can help us to design and build better aircraft and noise barriers, and to reduce the impact of noise pollution on our environment and our health.
