Does cloth absorb sound?

In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. How well a room absorbs sound is quantified by the effective absorption area of the walls, also named total absorption area.

Are cotton balls soundproof?

According to my data, cotton balls were the most effective sound proofer, followed by plastic bags, then the plaster of Paris, with foam in fourth, then shredded paper, and finally, the rubber mats, with the loudest tested volume, and thus the worst soundproofing qualities.
