sound mapping tools

We developed the Sound Mapping Tools (SMT) ArcGIS toolbox to provide an easy-to-use interface for producing spatially-explicit maps of sound propagation. Our goal is to facilitate studies of noise impacts on natural areas and wild animals. 

The toolbox is available free from the SMT Users' Group: http://purl.oclc.org/soundmappingtools. The users' group also provides a forum for questions about the toolbox, and for users to provide support to one another. SMT currently includes two sound propagation models, SPreAD-GIS (updated for ArcGIS 10.4) and NMSIMGIS, a GIS version of Noise Model Simulation (NMSim).

 Model predictions for noise levels from a train horn at the intersection of Laurel Avenue and Mason Street in Fort Collins, Colorado. Sound levels are sufficient to mask species' communication, for Northern Flickers ( Colaptes auratus ) on the Oval (green ellipse) or humans ( Homo sapiens ) in the Wagar building (blue circle).
