Directivity Correction for Internal Outlets    1/1

Strutt|Directivity|Internal Outlet Directivity inserts directivity corrections into the active row of the worksheet.

The following outlet positions have been included in the function:

Data for these positions have been sourced from Table 20, Arup Sound and Vibration in Mechanical Services Design. These directivity values are the cumulative directivity due to the outlet and its location in the room, rather than of the outlet itself. The additional condition of free space has been calculated with a correction of -3 added to the centre of ceiling values.
