Let's say you are listening to a recording in a large reverberant hall on a small speaker and you imagine hearing the echoes coming from the ceiling of that hall, behind the musicians...from a position far above the speakers, and far above the ceiling of your own listening room.
Your ability to imagine the acoustic space that was recorded depends on the ability of the recording system and your playback device to faithfully render the reflections off the surfaces of the ceiling. The microphone has recorded an initial tone AND the delayed reflection from the ceiling. Of course, the mic can't "tell" the echo came from the ceiling. But when you listen back, you may project the presence of that ceiling, because echoes give information about the relative distances and positions of the reflecting surfaces.
A lot of this goes on in the mind. That's why they call it psycho-acoustics. But the better the system, the more likely you are to be able to hear this.
