Answer 1

A sonic boom is the soundassociated with the shock waves created by an object traveling through the air faster than the speed of sound.Sonic booms generate enormous amounts of soundenergy, sounding much like an explosion. may this helps u. mark as the best or brainliest

Answer 2

Many objects like aircraft's, rockets etc travel at speed which is greater than the speed of sound in air. They are said to have supersonic speed.
Due to they high speed, a supersonic aircraft produces extremely loud sound waves called as shock waves in air.
The shock wave produced by supersonic aircraft carry a great amount of energy . The tremendous air pressure variations caused by the shock waves produce a loud burst of sound called as Sonic Boom .

Thus Sonic Boom is an explosive noise caused by the shock waves from aircraft or any other object which is travelling  faster than speed of sound.
