Why is a sonic boom so loud?
The many small pressure waves merge into a single shock wave moving at the speed of sound. The shock wave creates a rapid, intense expansion and contraction of air which reaches the ground. When the shock wave passes over you, it unleashes a loud clap of noise. That’s why sonic booms are so loud.
