Hi all,

Has anybody ever tried to interpolate sound (==> noise) in a general GIS? I 
only mean 2D interpolation. I know 2D is a big compromise but it has to be 
done for my school assignment and at this level I do not intend to use a 3D 

How would you treat the spread of a signal from a source r.cost is not a 
very good solution because of the refraction (picture the emission and 
imission points on the opposite sides of a building).

What about the reflection from objects?

Ideas and comments are welcome.
