    A walkthrough of the Marl example.

    The studio opens to the example near Marl, North Rhine-Westphalia — see the spec list below — we run it together: the night verdict at the eight homes, the source schedule, the unit classes and the receptor table.

  3. 03

    Then we look at your site.

    If the team takes you on, the next call is your own site: the yard, the homes you have identified, the rule you file under, and the margin at night. The same five-step studio, the same engine.

A real run on a real site, with the numbers, the units, the receptor table and the report at the end. Tell us your week and your time zone and we will write back.

The demo covers

  • The five-step studio, from address to run
  • The noise field, isolines and ray paths to the homes
  • The A-weighted octave spectrum at a receptor
  • The uncertainty class behind each unit's data
  • The receptor table with margin under uncertainty, per home
  • The report step (cover, source schedule, margins)

Look at the working first.

Every figure on this site comes from the example near Marl. See how the night verdict is built, what the margin looks like under its uncertainty, and what the numbers leave out.
