When an airplane flies at supersonic speed in the sky, it will produce a cone wave like a speedboat, and when two cone waves touch a space or object, it will produce a strong resistance, which will cause a very strong reaction, and this reaction will spread to the human ear and hear two loud noises, which is a sonic boom. Sonic booms occur only when airplanes are flying, and at supersonic speeds. Sonic booms have an impact on people's work and life because of excessive sound, and in serious cases, they will also cause glass to be shattered, including the collapse of many unstable buildings.
Why is there a sonic boom? It can be said with a layman's example. When we throw a stone into the water, there will be ripples on the surface of the water, spreading out in all directions, and then the whole surface of the water will be this ripple.
If a boat is placed on the surface of the water, the water waves become cone-shaped, and the generation of water waves is dispersed from the direction of the boat, and this water wave is wedge-shaped and propagates outward. The sound waves generated when the airplane is moving are dispersed like these water waves.
The sonic boom is only produced when the plane is flying at supersonic speed in the sky, and when the plane reaches a certain altitude, it will fly at supersonic speed, but because the shock wave will cause a strong change in pressure, so that we can hear the sonic boom. And this kind of sonic boom can only be heard outside the plane, and the pilot in the plane will not have such a feeling, and he will not hear this kind of sound.
The strength of the sonic boom is directly related to the altitude at which the aircraft flies, and the higher the altitude the aircraft flies, the lower the impact on the ground when the sonic boom is generated. On the other hand, when the aircraft flies at supersonic speed relatively close to the ground, the impact of the sonic boom on the ground is very huge. The milder effect is only for people to hear loud noises, and the larger effect is for the glass to shatter with a sonic boom.
Many people have heard of sonic booms at present, but almost no one has seen the effects of sonic booms on things, and at this time, airplanes can fly at supersonic speeds because they have reached a certain altitude.

A "sonic boom" is a loud sound caused by a shock wave when an object moves through the air at a speed that breaks through the speed of sound. The human ear cannot withstand the "sonic boom", and in severe cases even the nose will bleed.
-
When breaking through the sound barrier, a huge amount of energy is generated, and when it reaches the human ear, the person will feel a short and violent ** sound, which is a sonic boom, which will cause some damage to the human body and buildings.
-
A sonic boom is when the speed of an object is close to the speed of sound, and the energy is transmitted to the human ear, producing a short and strong ** sound, which may damage the hearing of the ear.
The propagation of sound in the air is like the water waves created by throwing stones into water, and it travels outward through the form of waves, which is called sound waves. The sound we usually hear is caused by sound waves entering the ear and causing the eardrum to vibrate. When an airplane flies at supersonic speed in the air, a wedge-shaped or cone-shaped wave will appear in the nose or protrusion like a speedboat moving forward in the water, which is the shock wave. >>>More

What is engine super knocking.
Engine "super knocking", also known as low-speed premature ignition, is an abnormal combustion phenomenon unique to supercharged direct-injection gasoline engines. When the engine inhales the mixture of fuel vapor and air, in the process of compression, due to the mixture of low ignition point substances in the fuel, it will cause the gas mixture to automatically deflagrate before the ignition of the spark plug, forming a new ignition point, and the flame spreads outward at a speed several times higher than the normal combustion, so that the cylinder wall is affected and vibrates, which is called detonation. To put it simply, knocking is a manifestation of abnormal pressure in the combustion chamber caused by abnormal combustion. >>>More
