(b) Adsorbent

(c) Reflective

(d) Refractive

This question was addressed to me in quiz.

Origin of the question is Acoustical Design of Halls and Studios topic in portion Acoustics and Ventilation of Construction & Building Materials

Answer 1

The correct choice is (a) Absorbent

For explanation I would say: The interior surfaces of walls in a studio should be of absorbent materials. However, the outer surfaces of the walls should be of the reflective type. Provision of windows should be minimum in order to prevent the noise from outside.
