Plantroom Noise Breakout

Strutt|Building Acoustics|Noise Breakout from Room calculates in the active row the sound power radiated from a plantroom, given the common surface area S of the plantroom and receiving room and the transmision loss TL of the partition.

Strutt calculates the noise breakout using the following formula:

`L_(W,rad) = L_(p,rev) + TL + 10log_10(S) - Cd`

`Cd` is -6 dB
