Score
NVH Lab analyzes the full sound spectrum and gives your car a Noise Score — NS.
Compare
See where your car ranks on the Fleet Board — against your model, your rivals, your next car.
Lower decibels.
Higher score.
Every car lands somewhere between library-quiet and truck-loud. Your NS puts your car on that scale — and on the board.
From a noise to a
shortlist of likely causes.
NVH Lab combines recordings across speeds, road surfaces, and operating states. It separates low-frequency boom and rumble, road and tire noise, wind noise, and tonal whine, then ranks likely causes using the available evidence and confidence. A hypothesis is never presented as a confirmed repair.
