Sonic Booms

To increase the intensity of a sonic boom, increase the size of the airplane. The larger the aircraft, the more air it displaces and the stronger the shock waves become. Also, the lower the altitude of the plane to the ground, the more intense the boom will be. That's because the shock waves will have less distance to travel before hitting the ground, and they will have lost less energy. To reduce the intensity of a sonic boom, decrease the size of the plane and increase the flying altitude.

A loud explosive noise caused by a shock wave from an aircraft traveling faster than the speed of sound.
