I think that the sound will be aborbed by the object then come out the outher side as if you put ear phones on.It keeps the sound in as much as it can.If it is totally covered it will be MUFFLED. new ans: the object will absorb all the energy and the sound will come out muffled.
A sonic boom occurs by an object traveling through the air faster than the speed of sound.
subsonic
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.
A sonic boom
Any object traveling at a speed faster than sound will break the sound barrier. That is around 340 meters per second.
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
A sonic boom occurs by an object traveling through the air faster than the speed of sound.
Sound speeds up when it goes into water from air. Sound travels much faster in water than in air.
Mach one is used to denote the speed of an object such as a jet plane traveling at or just above the speed of sound.
no sound never stops traveling!
Sound only happens when there is a collision with another object or a vibration from another object, because that is what a sound is. It can only be soft, loud, strong, weak, light, pitched etc. because it was moved by other existing objects. So sound happens when objects collide or become vibrated.
It will go down (Doppler Effect) because the apparentwavelength of the sound gets greater.
