How to keep a noise diary that gets taken seriously
A diary turns “it’s noisy all the time” into something a landlord, HOA or council can act on. The people reading it look for the same few things: a pattern, specifics and a calm tone.
Write it at the time
Add the line while it’s happening, or first thing the next morning. Entries made on the day are more believable than a list written up weeks later, and you’ll remember the details: when it started, when it stopped and what it sounded like.
Be specific
“Bass through the bedroom wall, 11:40 pm to 1:15 am, woke me at 12:10” says far more than “loud music again”. Write what you heard and how it affected you. Leave out guesses about why your neighbor does it.
Rate how loud it was, the same way every time
You don’t need a meter. Use the 1 to 5 scale at the bottom of the sheet and stick to it. If you also use a noise meter, note the level as approximate. A phone or browser isn’t a certified meter.
Note anything that backs it up
A recording, a photo of the time on your clock, a friend who heard it too, a message you sent at the time. Write it in the last column so you can find it later. Rules on recording differ by place, so check your local rules before you share recordings.
Keep going, even on quiet nights
Two to four weeks is a common ask, and quiet nights matter too: “nothing tonight” shows you aren’t exaggerating. Keep the originals, share copies, and add the diary to your complaint letter.

Questions
How long should I keep a noise diary?
Long enough to show a pattern. Two to four weeks is a common ask from landlords and councils, but keep going for as long as the noise continues. A few entries over a long time can matter as much as a busy week.
Do I need to measure decibels?
No. Most people never do. Use the 1 to 5 scale on the sheet, and be consistent. If you do use a meter or an app, write the level as approximate.
Can I keep the diary on my phone instead?
Yes. Download the CSV and open it in Google Sheets, Numbers or Excel. Paper works well too, because it is easy to keep up with at 3 a.m.
Who should I give it to?
Whoever you are complaining to: your landlord, property manager, HOA, city or council. Keep the originals and share copies.
