NoiseModelling is an open-source platform for simulating environmental noise propagation and generating regulatory-compliant noise maps at urban and regional scales. Leaded since 2008 by the Joint Research Unit in Environmental Acoustics at Gustave Eiffel University, it provides researchers and practitioners with reproducible, transparent, and scalable modelling capabilities for environmental acoustics. As the modelling core of the Noise-Planet framework, NoiseModelling simulates noise propagation from road traffic, railways, and industrial sources using the standardized CNOSSOS-EU method for emission and propagation. It operates as a Java library or through a user-friendly web interface, tightly integrated with spatial databases H2GIS or PostGIS to handle large-scale urban datasets efficiently. The broader Noise-Planet ecosystem complements NoiseModelling's simulation capabilities with participatory noise measurement through the NoiseCapture mobile application. After more than three years of operation, the platform has collected data from over 100,000 downloads and 74,000 contributors worldwide, enabling citizens and researchers to create high-resolution, crowdsourced noise maps that respect privacy while contributing to scientific research. This integrated approach bridges computational modeling with real-world measurements, promoting open science principles through open-source code, open data, and collaborative research.
