#1881: Simple 2D noise modelling using the SPreAD model<br>
-------------------------+--------------------------------------------------<br>

-------------------------+--------------------------------------------------<br>
The System for the Prediction of Acoustic Detectability (SPreAD) is a<br>
public-domain noise-modelling program for sound propagation based on<br>
weather, landcover, and topography. It has already been adapted into<br>
SPreAD GIS, an "open-source" (no license specified) noise model for<br>
ArcGIS. ([<a href="http://warnercnr.colostate.edu/~sereed/research/SPreAD-GIS.html" target="_blank">http://warnercnr.colostate.edu/~sereed/research/SPreAD-GIS.html</a><br>

<br>
A basic module for GRASS noise modelling could be developed based on this<br>
existing work, and AFAIK would be the first fully-open source noise model<br>
in a geospatial context.<br>
