1 Scope
This document facilitates a standardized interpretation and a verifiably consistent
software implementation of the sound propagation part of the calculation method CNOSSOS-EU:2015
according to ISO 17534‑1. Other parts of CNOSSOS-EU:2015, such as the source models or the calculation method
for aircraft noise, are beyond the scope of this document. This document provides
an agreed interpretation of ambiguous aspects of the sound propagation part of CNOSSOS-EU:2015,
a set of illustrative test cases along with reference solutions, and an example of
a template form for the declaration of conformity for software manufacturers.
