Names change. A building acquires an annex, a crate changes hands, and a cupboard becomes an archive without anyone putting up a sign. The old ledgers stay useful because they record what moved, who received it, and which door was used.
What belongs in a field note
Keep the place, sequence, and your interpretation separate. Write down what happened before the sound, what you heard, and what the room did afterwards. A useful description leaves room for another reader to reach a different conclusion.
Start with a recording
There is a practical pleasure in a well-kept ledger: the date, the delivery, the signature of whoever was meant to be there. Our fictional farm preserves that habit, alongside a less reliable tradition of identifying noises after lunch.
Listen to the sample collection and compare the notes. The labels concern the sounds; the stories concern the people who heard them.
