Acoustic Cloth And Carpet Available here. Acoustic cloth and carpet is an option for the interior of your vehicle to further enhance your comfort and the comfort of your passengers. You can opt for this type of carpet and upholstery to help quiet the inside of your vehicle from outside noises, such as other traffic. Some people also want to keep the sound of their music on the inside of their vehicle and this can be beneficial for that too. Acoustic cloth and carpet works to help absorb sound, reverb and echo. If you have an aftermarket sound system, this is a solid option because it will help to better cushion the louder and powerful sound that is coming from it.
