Browser-based acoustic mapping: sound-level surveys + ISO 9613-2 propagation with Maekawa diffraction on real OSM buildings. Live tool at /en/tools/acoustic-map/.

JavaScriptLeafletISO 9613-2MaekawaOpenStreetMapApache-2.0

Tool for environmental acoustics running entirely in the browser: visualises sound-level surveys (CSV with lat, lon, Leq) and simulates point-source propagation with a simplified model per octave band. Maekawa diffraction over real buildings fetched from OpenStreetMap via the Overpass API, with data transparency (% buildings with estimated vs measured height). Available both as a runnable web tool at /en/tools/acoustic-map/ (integrated into the ST-LINE site) and as a single-file HTML standalone in this repo, with vendored libraries and no runtime CDN dependency.
