本文件有助于根据ISO 17534-1对计算方法CNOSSOS-EU:2015的声音传播部分进行标准化解释和可验证的一致性软件实现。CNOSSOS-EU:2015的其他部分，如飞机噪声源模型或计算方法，不在本文件范围内。本文件对CNOSSOS-EU:2015中声音传播部分的不明确方面提供了一致的解释，一组说明性测试用例和参考解决方案，以及软件制造商一致性声明的模板格式示例。

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.
