Nissan Titan Truckumentary Film #8 Talks About NVH

This episode, titled "The Sounds of Silence," focuses on the noise, vibration, and harshness (NVH) measurements used to improve the interior experience in the all-new Nissan Titan pickup truck.


This latest installment of the Nissan Titan Truckumentary series focuses on noise, vibration and harshness (NVH). In The Sound of Silence (pause for the inevitable Beastie Boys quotes) showcases how Nissan's technicians isolate, dampen, or prevent noise and vibration in order to reduce road harshness and driver fatigue.

"People use the truck to go camping on the weekend, to go to dinner with their families, and they use it as their work vehicle. So it"s important for the truck to be functional, but just as important to be able to take phone calls and be able to work and live in the truck. Quietness is a key selling point for a lot of people for full-sized trucks now," says John DeYoung, Senior Manager of Nissan"s Noise and Vibration Test Group.

Sound quality testing is showcased in this video, which illustrates how technicians put up to 120 microphones on the truck to test specific NVH qualities, such as powertrain noise, chassis vibration, and more. The balance is in finding the right point where the exhaust note of the big Cummins five-liter is heard in a pleasing way without intruding on the interior experience overall.

Most of the testing has taken place in Farmington Hills, Michigan in the lab of the Nissan Technical Center North America and on the road in controlled outdoor testing at Nissan's Arizona Test Center in Stanfield.
