With this option, the user can determine elemental noise source contributions from a part of the site (polygon area).
To design a new ray zone analysis:
•From the ribbon Simu - Renderings, by clicking on the button 
 in the group Analysis, then draw the area.
•When the zone has been drawn press ENTER.
To use a zone
When rays are displayed, select a zone. All rays inside the zone will be selected. The tab with cumulated contribution values appears. By analyzing several zones, the length of a noise barrier can be dimensioned.
