This clip is a seven-second recording of a household smoke alarm sounding its shrill, repeating beep, with no voice or music over it. It feels urgent and instantly annoying in a funny way, creating a small sense of panic that listeners recognise from burnt toast, dead batteries and middle-of-the-night false alarms at home.
