An Acoustic Surface is a special type of SubStructure that is used to display acoustic data.  Acoustic data is typically taken on a grid of spatial Points in the vicinity of one or more noise sources.  SPL , Sound Power & Acoustic Intensity data is typically displayed on an Acoustic Surface.  Acoustic surfaces are easily created by using the Drawing Assistant in the Structure window.

Acoustic Surface Showing Areas & Normals.

Each of the 30 bold measurement Points is surrounded by 4 Points which define its acoustic area.  Acoustic areas & normals are calculated when an acoustic surface is created in the Drawing Assistant.  Acoustic areas & normals  are listed in the Points spreadsheet, and must be edited if the Point coordinates are changed.
