How to use this as evidence: Environmental health officers and councils accept noise diaries as supporting evidence for noise complaints. Record entries over at least two weeks to show a pattern. The audio recordings you capture here give officers an idea of what you are dealing with even when they cannot visit in person. You can export your diary as a PDF to attach to a complaint or use our noise complaint letter builder to write a formal letter.
Noise level guide: 30 dB is a quiet room, 50 dB is normal conversation, 70 dB is a vacuum cleaner, 85 dB is heavy traffic, 100 dB+ can damage hearing. Most council noise thresholds consider sustained noise above 34 dB at night as a potential statutory nuisance.
