●
If you know the insertion loss between areas, set 1/2 of the insertion loss as the insertion loss of the wall
for each area. If we use the figure below as an example, when the insertion loss between area 1 and area
2 is known to be 10 dB, set 5 dB for the insertion loss of the lower side of area 1 and also set 5 dB for the
insertion loss of the upper side of area 2.
