Full title and description

St ISO TR 17534-2-2014 — Acoustics — Software for the calculation of sound outdoors — Part 2: General recommendations for test cases and quality assurance interface. This technical report provides non‑normative guidance for implementing outdoor sound‑propagation calculation methods in software, a geometrically described set of test cases for verification and validation, and a description of a Quality Assurance (QA) interface to support data exchange between software products quality‑assured according to ISO 17534‑1.

Abstract

ISO/TR 17534‑2:2014 contains additional recommendations to help software developers and users implement calculation methods for outdoor sound propagation correctly. It defines a general, applicable set of geometrically described test cases and specifies a QA interface that enables exchange of test and result data between software programs that follow the ISO 17534 series quality assurance approach. The document is intended to support consistent implementation and to facilitate verification and comparison of results from different acoustics software tools.

Scope

This technical report provides general recommendations for the implementation of outdoor sound‑calculation methods in software. It supplies a set of geometrically described test cases intended for verification and validation of implementations, and describes a QA interface to allow exchange of data (inputs, test definitions, expected/reference results and computed outputs) between software products that have undergone quality assurance according to ISO 17534‑1. The document is advisory (technical report) and complements the normative requirements and QA processes defined in ISO 17534‑1 and related parts of the 17534 series.

Key topics and requirements

• Recommendations for reliable implementation of outdoor sound‑propagation calculation methods in software.
• A general, geometrically defined set of test cases for verification/validation of calculation engines.
• Specification of a Quality Assurance (QA) interface to support standardized data exchange between quality‑assured software tools.
• Guidance to ensure reproducibility and comparability of results from different software implementing the same calculation methods.
• Advice on documenting test results and declaring conformity consistent with ISO 17534‑1 processes.
• Non‑normative examples and implementation notes to support developers and test engineers.

Typical use and users

Primary users are software developers and QA engineers who build, validate or certify acoustics software for outdoor sound prediction; acoustical consultants and modelling specialists who need to verify tool correctness; regulators and authorities that require demonstrable software quality for noise mapping and environmental assessments; and researchers and educators working on sound propagation modelling. The report is useful when establishing verification test suites, implementing QA workflows, or exchanging test data between tools.
