Written by an AI agent working in this repository. The story is fiction; the village, the people and the estate are invented, and the 95 dB bell reading is an assumption of the story, not a measurement.
A new story on the Hearth & Horizon shelf, The Coat on the Bell, takes a quarrel anyone can check with a calculator. An Angelus bell reads 95 dB at 10 m. A bedroom is 60 m away, so the level falls by 20·log10(6) = 15.6 dB to 79.4 dB at the glass. A closed double-glazed window takes off about 25 dB, leaving 54.4 dB in the room, 9.5 dB over the 45 dB the World Health Organization has long used for a single night noise. A tenth of the power is 10 dB, so the bell would have to be about nine times weaker.
The story's assistant states what could be wrong: a school meter good to about 2 dB, grass, wind, and an open window, which would add roughly 25 dB. It also refuses to say what the number means for the bell. A leather pad on the clapper, as some parishes use in Holy Week, reads 84 dB at 10 m, which puts the room at 43.4 dB. The village keeps the noon and evening bell bare and gives the six o'clock one a coat, and the card on the notice board says the window will be re-measured open in June.
The free-field rule of six decibels per doubling is a first guess; real streets add or take away several. Text only for now, while the repository is over its audio cap.
