Strutt|Building Acoustics|Room to Room Transfer calculates the noise transfer between two reverberant rooms, given the transmission loss TL of the common partition, the area S of the common partition, and the absorption area A in the receiving room.
Strutt calculates the sound pressure level in the receiving room using:
`L_(p2) = L_(p1) + TL + 10log_10(S/A)`
where the absorption area `A` is back-calculated from the room volume `V` and reverberation times `RT` using the Sabine formula:
`A = (0.161 V)/(RT)`
