Noise level
How loud each room is, from the phone’s microphone: an uncalibrated A-weighted level per room, best read as which rooms are quieter.
What it answers
Section titled “What it answers”- Which bedroom is quietest?
- How loud is the street side?
For the agent, the tool is described as: Phone only: a person runs this from the phone app, an agent cannot. A-weighted sound level (LAeq) per room from a phone microphone, as a per-room lens, against the WHO indoor guideline levels. Uncalibrated: absolute levels are good to about 10 dB, differences between rooms to about 3 dB. Needs readings from the phone app.

How it works
Section titled “How it works”Noise level: an A-weighted sound level per room from the phone’s microphone, as a lens.
Reliability
Section titled “Reliability”Every metric and finding carries its layer, its method and a high, medium or low label, set by the tool for each value. See findings and reliability.
Limits
Section titled “Limits”- Needs: phone.microphone. On a scan without it, the verdict is
unknownand says why. - A result is a planning aid, not an inspection.
On the made-up test home
Section titled “On the made-up test home”This section was written by running the tool when the docs were built, on a hand-made RoomPlan export (no real place was scanned), with no sponsor keys and the network switched off.
Not run: it needs readings, which only a person or a phone on site can give.
