Strutt|Building Acoustics|Enclosure calculates the sound power radiated from an enclosure, given the row of sound power levels (Lw), the row of transmission loss values (TL) and the enclosure conditions, and inserts the results into the active row on the worksheet.
Constant C is a factor accounting for internal enclosure conditions, and has the following octave-band values:
|Enclosure Internal Acoustic Conditions||63 Hz||125 Hz||250 Hz||500 Hz||1 kHz||2 kHz||4 kHz||8 kHz|
The following guidance is given as to selecting the acoustic conditions within the enclosure:
