It has already been adapted into SPreAD GIS, an ""open-source"" (no license specified) noise model for ArcGIS. ([http://warnercnr.colostate.edu/~sereed/research/SPreAD-GIS.html Project site]) A basic module for GRASS noise modelling could be developed based on this existing work, and AFAIK would be the first fully-open source noise model in a geospatial context." enhancement new normal 7.6.2 Raster svn-trunk noise, sound All All
