3M Sound Deadening Pad blocks noise from the outside world so that passengers in a car, truck or van can ride in quiet comfort. Our pad suppresses noises from many sources, include road noise, engine sounds, rattles and squeaks from the vehicle. So while there may be many distracting noises outside of the vehicle, the interior cabin will offer quiet solitude. Road tested to the high standards of the European market, our sound deadening pads work to suppress noise and vibration.
