Sound waves do not move in space; they require matter to be passed on. Sound waves that reach space essential peter out, much like surf waves of an ocean when they hit shore. But at least theoretically, if there were strong enough sound waves to begin with, they would bounce or echo off the edge of the atmosphere and move back toward the earth's surface. Think of a cord tied off at one end and held taut by you at the other end. A quick 'wave' given to the cord will travel to the tied end and back to you. In other words sound would probably behave like radio waves but with much less energy, and they would rapidly be absorbed by the atmosphere itself.
When a sound wave is reflected off a wall as an echo, it bounces back and reaches our ears after a short delay, creating a repeated and fainter version of the original sound.
When a sound wave hits a wall, the amplitude of the wave decreases due to reflection. Some of the sound energy is absorbed by the wall, some is transmitted through it, and some is reflected back into the original space. This results in a decrease in the overall energy and amplitude of the sound wave.
When a P-wave reaches the outer core, it undergoes refraction due to the change in density of the material. This causes the wave to slow down and bend as it travels through the outer core.
When a wave reaches the edge of an object, it can either undergo reflection, transmission, or diffraction. Reflection occurs when the wave bounces off the object, transmission happens when the wave passes through the object, and diffraction occurs when the wave bends around the object. These interactions depend on the properties of the wave and the object it encounters.
Since we don't know what "this wave" is, we cannot answer the question.

A reflected sound wave can be one of two things, an echo or a reverberation. Reverberation happens when sound bounces off surfaces and reaches back to the ear within 0.1 seconds. Echoes happen when sound waves bounce back to the ear after more than 0.1 seconds.

Sound wave
Yes, sound travels through space when the space is filled with some medium such as air (or water or iron or cetera). Sound is vibrations in the medium which travel as a wave. If there is nothing in the medium, no sound travels through it. Outerspace is pretty empty. You won't hear anything if you're in outerspace (except sounds from inside your space suit/ship). P.S. Do you mean the sound of a wave (like splashing on rocks) or a sound wave?
it changes
I don't understand your questions. I know that our ear drums and the microphone diaphragms are moved directly by the sound pressure p, that is a sound field quantity. Forget the sound energy quantities when you talk about ears.
When a solid barrier reaches the wave barrier, it will prevent the wave from propagating further. The solid barrier will absorb or reflect the wave energy, causing a change in the wave pattern and possibly generating new waves as a result.
