1. About the situation

All optional. Leave anything blank you don't want in the packet.

Your name

Contact (phone / email)

Affected property

Suspected source

Landlord / HOA / property manager

Short statement

2. Log incidents (0)

Log each event as soon as you can, ideally while it's happening. Logs made at the time carry the most weight.

3. Measurements (optional)

Phone apps and dB(A) settings under-read low-frequency sound. Use dB(C) or dB(Z) if your meter allows. See Detection & Evidence.

Meter / app (make and model)

Weighting you usually use

Last calibrated (if known)

How you measure

Import a meter export (CSV)

Many meters and apps can export readings as CSV. The packet shows daily maximum and energy-average (Leq) values, plus a fingerprint of the original file. The full file stays with you.

Choose CSV file

4. Complaints and contacts (0)

Every time you report it to a landlord, council, police, or HOA. This record shows you used the proper channels.

5. Photos and files (optional)

Each item gets a SHA-256 fingerprint, a code anyone can recompute later to confirm the original file hasn't been changed. Files never leave your device.

Photos to include

e.g. where equipment sits against a shared wall. Photos are printed in the packet but are not saved. Re-add them if you come back later.

Add photos

Recordings and other files

Audio, video, or meter files you're keeping as originals. The packet lists each one with its fingerprint.
