Which of the following is the best absorber of sound? a) Wood b) Thermocole indoor c) Iron d) Cardboard
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 the total absorption area.
Of the given four options, cardboard is the best absorber of sound. I think the next absorber of sound is wood.
