Unique identifier sound created when the door of the room is opened: generated using combinations of ambient light intensity & color, temperature, humidity, etc, and their collective temporal changes. The generated sound is a fingerprint/unique identifier, but meaningful not in its injective function-ality itself but instead the expression of such identification. Opening and closing the door to listen to such sounds creates several distinct spaces separated by time and defined along dimensions of ambient characteristics.
