PA Loudspeaker Level    1/1

Strutt|Input Data|Empirical|Typical PA Loudspeaker Directivity inserts the typical on-axis sound power levels of an outdoor-type PA system (e.g. for an industrial plant) into the current row of the worksheet.

Strutt includes two spectra: for "average speech" (assumed to be `L_(eq)`), and for 1% peaks (i.e. `L_1`) from Table 8.13 of Laymon Miller
