Ambient Sound

The resident can now identify their neighbor's schedule from the lift's arrival pattern and has not tried to do this.

The generator ran for six hours without notice and its absence was heard immediately across the entire building.

The room was silent for the first time in four hours and the silence was louder than the machine.

The beep has been acceptable for six weeks and became intolerable at 11:47 PM on a Tuesday.

The subject can reconstruct the identity, pace, and probable destination of a corridor resident from three footsteps and a door sound.

The subject began counting pressure cooker whistles at some point and cannot identify when counting became automatic.

The traffic has been there every night. One horn at 1:34am was different, and now there is no going back.

The keyboard has been the same keyboard for two years. The library knows about it now.

The refrigerator has been running since it was installed. It is only audible after midnight.

The rain made staying inside feel like a decision rather than an absence of going outside.

The ceiling fan has made the same noise for six weeks. Tonight it became unacceptable.

The renovation has been ongoing for six weeks. The drilling schedule is now memorized involuntarily.

A ceiling fan runs unnoticed for hours until it stops, at which point it becomes the only thing in the room.
