Vehicles are getting lighter and quieter every year, and an array of products work behind the scenes to keep them that way. As new materials such as aluminum and thinner sheets of metal reduce weight in vehicles, additional reinforcement sometimes is needed. To reduce noise, sound-dampening materials are installed behind door panels and vehicle ceilings. But all sound is vibration, so reducing noise also requires dampening the vibration of components.
“Customers are demanding quieter cars,” Vice President of Sales Denny Pedri observes. “The need for quiet started with telematics and the introduction of Bluetooth in cars. Customers want to have conversations without hearing road, engine and wind noise. This is driving the push for quieter interiors, which also gives the impression of a better car. The overall intention is to make the car library-quiet.”
