NVH (Noise, Vibration, and Harshness)

Category: science

The industry standard metric for measuring the cabin quietness, smoothness, and ride comfort of a vehicle.

NVH is the "sensory test." Automakers use acoustic glass, thick sound deadening, and sophisticated bushing materials to isolate the driver from road, engine, and wind noises. High-tier luxury brands are defined by their superior NVH suppression, creating a "vault-like" cabin feeling.

Common Examples

• The consumer report highlighted the mid-range crossover’s impressive NVH suppression, comparing it favorably to vehicles costing twenty thousand dollars more.
• Excessive road noise and steering wheel vibrations are clear indicators of poor NVH engineering and cost-cutting on sound-deadening insulation.
