Rest(less)room
We perceive our space through what we see and also what we hear.  Reverb draws the invisible map of our surrounding space; it usually matches the reality we know. 

But what if it doesn’t? 

Different reverbs are designed for each of the cubicles at the AA's female toilet - a space we seek privacy and security, yet our visual perception is limited and we rely on sound to read the environment. The designed reverbs will make us doubt our reality, from our location to the person next to us, and even ourselves.
