A sound wave moves, and if the emitter moves as well, the leading edge of the wave is compressed and the trailing edge is enlongated. It's not about things being bigger or louder. Things are louder closer to you because they've lost less force in interaction between yourself and the emitter.
If there are barriers between yourself and the emitter - you won't hear anything at all...and the person behind will hear the same thing they would regardless of whether or not there are barriers between you and the emitter. Just expunge the idea of bigger and louder entirely out of your mind.
^^^^^ This, this right here is what I think I understand.
