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

Yes, it is true that carpets and curtains/drapes placed on the floor or wall surfaces can reduce noise level because these items absorb sound waves. For example, the slightest whisper can be heard clearly in a room without any furniture but not in a well-furnished room. This is because the furniture acts as sound absorbers.
