34 User Manual SONarchitect plots the Normalized Levels Difference DnT [dB] in the bar graph. It shows a quite low airborne insulation for the lower frequencies. The 3D model shows the transmission path. By the representation it becomes evident that it corresponds to the direct transmission, and that the sound insulation problem is due to the door, which presents a fair low sound insulation. To experience another example of complex geometry just browse till “Floor 2” > “Room 30 (Common Area)” > “from room 9 (elevator)”. © 2012 Sound of Numbers S.L.
