Conti, Pirelli develop tires with noise-damping technology for Audi

摘要

MILAN, Italy— Pirelli Tyre S.p.A. and Continental A.G. have developed tires for Audi Group that are designed to reduce noise for occupants of the car by using a layer of polymer sponge that is adhered to the inner liner of the tire. Pirelli claims the innovation—being pitched as "Pirelli Noise Cancelling System"—can reduce the noise heard by those inside the car by 2 to 3 decibels, or roughly half. Conti claims its technology—dubbed "ContiSilent"—can reduce the lire-generated noise level reaching a car's cabin by as much as 9 decibels.
