Summary
The article is updating its reporting of vehicle interior noise to give readers a clearer sense of how loud cabins actually feel. Traditionally, they used A-weighted decibels (dBA), a logarithmic metric that downplays low frequencies and is hard to interpret. Now they’re also reporting sones, a linear scale tied to human perception of loudness, alongside dBA in tests conducted at their Michigan facility with a standardized sound meter. This change makes comparisons more intuitive—for example, a Mustang GTD’s idle registers 10 sones, 43 % louder than a Corvette ZR1’s seven sones. Quietest measured at 70 mph so far is the Genesis Electrified GV70.
