Answer»

The correct choice is (B) False

To explain I would say: There are three PHENOMENONS that happen when SOUND waves strike the surface of a room. These are reflection, absorption and transmission. The amount of sound transmitted outside a room DEPENDS on the sound insulation properties of the surface while the amount of sound reflected or ABSORBED depends on the surface.
