Strutt|Input Data|Empirical|Steam Turbine inserts sound power levels into the active row of the worksheet.
The total sound power level is calculated by:
`L_W = 93 + 4log_10(kW)`, (dB re 10-12 W)
Octave band sound power levels are then calculated by subtracting the corrections listed in Table 11.17 Bies and Hansen.
