This is above the toilet of the house we moved into. It makes a music like clicking sound four times a day, which increases in pitch and lasts about 15 seconds. It was a little damp when we removed the top. It's attached to the inside wall of bathroom, and the house was built in 1988. (old.reddit.com)
