Aural space

Aural space, also known as "auditory space" or "acoustic space" is the sense of the physical environment of a perceiver conveyed by the quality of sound.

The acoustic environment in which sound is heard is characterized by the interaction between sound and a room, either by absorption, reflection, or diffraction by the walls.

So for example the same sound produced in a cavernous warehouse and in a small room will convey to a listener cues about the dimensions of the space, the placement of walls etc.
