The sound of a sonic boom is the engine noise and vibration of the aircraft, only greatly amplified.
Sound is a reverberating pressure wave that travels through air at a constant rate. Sound waves move away from the plane in all directions as it travels, but at the speed of sound these pressure waves at the nose can't get clear of the plane and so begin to 'stack' together, resulting in a much stronger wave and an extremely loud noise.

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 ocean wave will get smaller when it reaches shallow water. Waves will always be higher and faster when traveling through deep waters.

We generally refer to the sound we hear when a supersonic object passes somewhere in our vicinity as a sonic boom.+++A sonic boom is the shock-wave created by an aircraft accelerating past the speed of sound breaking through a pressure-wave formed in the slip-stream around the aircraft's nose.

Supersonic speed is a rate of travel of an object that exceeds the speed of sound. An object traveling in dry air at a temperature of 68-degrees F, at sea level, reaches supersonic speed at 768-miles per hour. Since the retirement of the Concorde, there are no supersonic passenger aircraft left in service. The speed of sound decreases somewhat with altitude, due to lower temperatures found there.
It reaches it's target and detonates. -Almost all aircraft borne missiles travel at least 3,500 mph or more - far in excess of the aircraft sped.

Because the propeller would turn at excessive RPMS if it were coupled directly. If a propeller reaches supersonic speeds, it actually impedes the aircraft.
it would take 36 minutes.

Every run produced must have a runner reach first base.
