The question was asked in an online quiz.

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

Answer 1

The correct answer is (c) Total absorbing power

To explain I would say: In Sabine’s expression for reverberation time t=0.16V/A, A represents total adsorbing power. It is expressed in m^2 sabines. In this expression, V represents the volume of the room in cubic metres.
