Pirelli’s sound absorbing sponge reduces the frequency filtering through the car, providing superior comfort compared to traditional tires.
The Pirelli Noise Cancelling System reduces noise by two or three decibels, on average reducing it by half, with a consequent improvement in driving comfort.
Foam material inside the tire cavity absorbs the resonant air wave
Open cell foams are commonly used to maximize the interactive surface: the sound wave is scattered inside and between cells, leading to noise reduction
