How many sonic booms does a plane make when it travels faster than the speed of sound?

When a plane travels faster than the speed of sound, it creates a single sonic boom, which occurs when it breaks through the sound barrier. However, as the plane continues to fly at supersonic speeds, it can produce multiple sonic booms depending on its flight path and altitude. Each sonic boom is a result of shock waves generated by the aircraft, which merge into a single boom as the plane passes through the sound barrier.
