Question

The amount of sound transmitted outside a room depends on the surface while the amount of sound reflected or absorbed depends on the sound insulation properties of the surface.

(a) True

(b) False

This question was addressed to me in class test.

This is a very interesting question from Acoustics topic in division Acoustics and Ventilation of Construction & Building Materials

Answer 1

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.
