Is it true that carpets and curtains/drapes placed on the floor or wall surfaces can reduce noise level? Explain briefly.

(N/A) Yes,it is true that carpets and curtains/drapes placed on the floor or wall surfaces can reduce noise levels. These materials are porous and soft,which makes them excellent sound absorbers. When sound waves strike these surfaces,the energy of the sound is dissipated within the fibers of the material rather than being reflected back into the room. Consequently,they act as muffling devices that help in reducing echo and overall noise pollution in an indoor environment.
