The sound can always be heard as a loud bang when the jet plane whizzes past and tears its own sound cone behind it. The result is Mach 2 which is supersonic speed. However, if the object moves faster than Mach 1, it overtakes the sound. If it moves with Mach 1, it is as fast as the propagation of the sound. It describes the speed of an object with relation to sound. At the top, the energy is released and hits a speed of Mach 2 within 0.0026 seconds and we hear the sonic boom. With every blow, the sound travels along the whip rope like a wave. Indiana Jones’ favorite toy is one of the most remembered examples of overcoming sound barriers. The bang can always be heard when an object whizzes past our ears at supersonic speed regardless of whether it’s an airplane, ammunition, or a whip. Jet fighters, bullets, and helicopter rotor blades rattle the sound barrier every day. Since then it has been booming everywhere. The desired effect finally came when the plane pierced its own sound barrier with an extra boost. The resistance in the air built up to a speed of 340 meters per second in front of the rocket jet. The Bell X-1 rocket plane was not only fast enough but it was also stable. The breaking of the sound barrier actually took place for the first time in 1947.

The cloth falls off conically behind the curvature. This phase can be compared to a stretched cloth into which a finger is bored. And at the front of the plane, the wave jams out of air. It moves in a cone shape behind the aircraft. It is the same with sound, only three-dimensional. The tip is at the front of the pen, the waves drift away from it. When viewed from above, an image created looks like a triangle. But when the pen is quickly pulled through the water, the waves pull behind it and a bow wave foams up at the front. Simply dipped into the water, it creates circles like the stone. The airflow becomes stronger and the flight behavior uncontrollable. The problem is that the faster the aircraft gets, the more sound it pushes in front of it. Some types of fighter planes were able to reach speeds of sound in a dive, but could not break the sound barrier. The jet slowly but surely catches up with its own sound creating a sonic boom.ĭuring the Second World War, the first aircraft were already close to breaking the sound barrier. The sound waves rushing away from the aircraft spread quickly, but not rapidly enough. Jet fighters are not stones, but high-speed planes. The sound always spreads spherically similar to the circular waves that a stone creates when it falls into the water. So, is there a barrier that is responsible for the noise? There is actually a kind of wall in the air and it can be better explained by the term ‘wall of resistance’. It means that it has gone past the speed of sound. The sound called the sonic boom is heard when the fighter jet has broken through the sound barrier. A couple of seconds later, the pilot only appears as big as a fly but the sound of the aircraft booms in the ears. A jet fighter rushes past with incredible speed. ©Pixabayįirst, you see it and then you hear it. But what is the reason for sonic boom, the bang when the sound barrier is broken and how do you imagine the wall? Let’s find out. It recently happened in Bengaluru when people claimed they have heard the noise from an alien aircraft. You might have even heard the sound barrier, breaking. Airplanes and lashes have something in common, they can break the sound barrier with a bang or sonic boom.
