Automotive engineers have been tackling unwanted vehicle noise for decades. Their focus consists of a combination of sounds and vibrations from a vehicle’s drivetrain, as well as ambient road noise from outside vehicles.
In the small town of Wauwatosa, WI, sits the state-of-the-art noise, vibration and harshness laboratory operated by Briggs & Stratton. Within the lab are two anechoic chambers outfitted with sound-absorbing acoustic wedges.
Automakers spend a lot of time focusing on noise, vibration and harshness (NVH). That’s because many consumers demand vehicles that are as quiet as possible.
