What you get
One recording. The whole picture.
The Drive Test
Secure your phone and record 10 seconds of a road you know. That is the whole ask.
The Noise Score
Every Drive Test becomes an NS from 0 to 100, compared only against cars in the same speed band and on the same road surface. Higher means quieter.
Your Garage
Every car, every Drive Test, every change — a history that makes the next new noise much easier to explain.
The Fleet Board
See where your car ranks among every model the community has measured — and put your own model on the board.
Comparisons
Before and after new tires, a repair, or sound treatment — measured on the same stretch of road.
Honest data
Quality grades and clipping flags on every recording, so you only ever compare data you can trust.
The honest part
This website is a taste.
Here you can see the top of the Fleet Board and run one free comparison check. The app has the full board, your complete history, and every comparison — free.
Free to start
Your first score is 10 seconds away.
