no, there is only one speed where a sonic boom would occur, and that's at the speed of sound.
sound travels at 343 m/s so an object traveling as less then the speed of sound would hear the noise its producing around it. as the object approaches the sound barrier, the noise being produced by the object slows down relative to object. once the object goes faster then the speed of sound, there is a sonic boom as the object pierces through the sounds waves being produced. in effect, the sound waves being produced are traveling slower then the object producing them. that's why if you watch a supersonic jet goes by you see it pass you before you hear its engines roar.
He could run at sonic speeds.
Sonic's The Name, Speeds My Game
Sonic is a skilled fighter, and can run at supersonic speeds.
Never, he speeds past it.
Here we go,I'm speed,or Sonic's the name speeds my game.
At sub-sonic speeds, air resistance is fluid friction. At supersonic speeds, it is not.
Only when flying. When he is running, he cannot reach super sonic speeds.
