Evidence checklist (better evidence = faster handling)
- Noise log: date, start/end time, duration, where you heard it in your unit.
- 30–60s audio/video clip: capture the noise character; avoid filming private areas/people.
- Location details: your unit number/floor; suspected direction (upstairs/next door/opposite/site).
- Impact summary: sleep disruption, study impact—keep it factual.
- If you messaged them: screenshots of polite, short messages.
