This is programming part of my diploma thesis at GIS postgraduate studies at University of Gdańsk called:

Noise propagation model. Implementation of International Standard ISO 9613-2 “Acoustics – Attenuation of sound during propagation outdoors – Part 2: General method of calculation”

It is an ArcGIS Python Toolbox (Python + ArcPy and Numpy packages). To use it you need ArcGIS Desktop software >= 10.0.

To find more check poster.

In IsoNoise Python Toolbox there are 3 tools:

1. Create Project - define project folder. Toolbox will optionally generate a template for model features (buildings, point sources, calculation areas, etc.)

2. Import Data - give a paths to project features. Optionally you can only update some of them.

3. Run Project - start calculations. You can choose calculation type: Receiver or Grid. Furthermore, you have a lot of settings, so if you know ISO 9613-2 Standard you can get into depth. If not just leave defaults.

• Calculation Settings

• Environment Settings

• Model Settings

Using other interpolation tools you can prepare maps with noise level areas like below:
