Want this question answered?
YesWhen a plane goes through the sound barrier, it produces a wake like a boat going through water. The wake(or waves) propagate out from behind the plane in a cone. Any observer outside this cone does not hear the plane until the shock cone reaches him.If you are a passenger on the plane, then you are traveling the same speed so the sound waves will reach you easily.It is like the illustration of a Fly inside a plane. The Fly can still fly from the back of the plane to the front but he is not going supersonic. He would appear to be going supersonic to someone on the ground.ALso, read the observations of the Astronauts. Their space shuttle reaches Mach 2 or 3 before engine separation and I'm sure they will describe the change in sound.ALTERNATE QUESTION:Do you hear your rockets if you are in Space? There is no atmosphere in space so sound can not travel. However, there is atmosphere inside the rocket so they do hear the vibration.
the bats do not produce supersonic sounds.they produce ultrasonic sounds.Thats the reason we cant hear them
Because it is travelling faster than the speed of sound, the sound comes later. However, if a fighter plane was slower than the speed of sound, you'd see the plane first.
no
A boom. However, for anyone inside the airplane they do not hear anything. Older planes not build for supersonic speeds could shudder and vibrate due to the turbulence.
Because the plane is flying faster (and therefore ahead of) its own sound.

False.
Yes, but it is travelling supersonic so you don't hear it until it has passed you or just reached you Not all bullets are supersonic.
You would hear the sound after the plane has passed.
bats can hear sounds of higher frequency than humans (supersonic) because they produce them and these sound waves echo back to them by bouncing of items so that they can see how far something is. Just like in submarines. therfore they need to 'hear' these 'supersonic' waves to see.

Yes, sound waves exist which are not audible to the human ear. Humans can hear sound waves having frequency between 20 - 20,000 Hz. Other all frequencies lie outside our hearing range and are called ultrasonic or supersonic waves.
Yes - but it will be travelling fast ! You will hear the sound of the engines a few seconds after the plane passes overhead.
