When Do Sonic Booms Occur?

A sonic boom does not occur only at the moment an object crosses the speed of sound; and neither is it heard in all directions emanating from the supersonic object. Rather the boom is a continuous effect that occurs while the object is travelling at supersonic speeds.

Why do sonic booms happen?

A sonic boom occurs when an object moves faster than the speed of sound. As it moves through the air, it creates shock waves that can cause a loud, booming sound. It is mostly emitted by aircraft that travel at supersonic speeds.

How often do sonic booms occur?

A report published on Wednesday has warned that commercial supersonic aircraft could create sonic booms as often as once every five minutes in certain regions. It also warned of significant impacts on the environment and public health. The U.S. is reportedly pushing for a return to faster-than-sound travel.
