Acoustic Surfaces

An Acoustic Surface is a special type of Substructure that is used to display acoustic data in a Structure window.  Acoustic data is typically taken on a grid of spatial Points in the vicinity of one or more noise sources.

The Acoustic Area and Acoustic Normal of a Point are used to calculate Sound Power through the surface from Intensity data.

Each of the 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.
