Before a measured survey exists, an architect still needs to know which edge of a site faces the traffic and where the quiet courtyard could go. Pick a site and MapToNap draws two noise sheets: road noise zones graded by street type, and a map of the sound sources nearby — traffic, people, leisure, industry and rail, water and green. Both come out as editable vector drawings in the style of the rest of your set.
Every street is drawn by how loud it is likely to be: main roads, collectors, local streets and the quiet areas away from traffic, with the share of the site near main roads and the distance from the site to the nearest one.
A second sheet places the things that make noise around the plot — traffic, people, leisure and sport, industry and rail, water and green — sized by how loud each type usually is.
Both sheets say on the drawing that they are estimated from mapped streets and features, not measured. They are for orientation and early design, not for an acoustic report.
Rendered by MapToNap on the Paris sample. The boulevards and the bridges set the loud edges; the river and the block interiors stay quiet.

Search an address or click the map. The sheet is centred on the point you choose.
Both are Pro analyses. Add any other studies you need to the same set.

No. It is an estimate from the type of each mapped street and the features around the site, and the sheet says so. Use it to see which edges are likely to be loud early in design. For planning or acoustic compliance, use measured data or a strategic noise map from your local authority.
From OpenStreetMap. The result is only as good as the mapping around your site, so check that the main roads and the pedestrian streets are tagged correctly.
Noise Analysis and Sound Sources do not. Road Noise · Aural Topography, a Max analysis, traces sound from every street and shows how the buildings around the site shield it.
Noise Analysis and Sound Sources are part of Pro. The free version covers the figure–ground, street network, land use and green & water drawings, with a watermark.
Yes. The SVG export is vector geometry you can restyle in Illustrator, Affinity or Inkscape. A vector PDF and a PNG are also available.
