cabin noise ratings cars 2023

Cabin noise ratings are usually measured in dB(A) at a steady cruise, and for 2023 cars you’ll typically see anything under 67 dB(A) counted as “quiet”.

Luxury sedans and many EVs can sit around 64–67 dB(A) at 100 km/h, mainstream small/medium SUVs hover near 68–72 dB(A), and ladder-frame utes often land around 72–76 dB(A).

Tyres, road surface and wind all matter; swap to quieter rubber or laminated glass and you can drop a couple of decibels without selling a kidney.

There’s no single Australian standardised test, so compare like-for-like road speeds and surfaces from reputable reviewers, and ignore “my cousin said” science.

Consult official documentation for exact figures.
