Overview
EN 1793-3:1997 is a CEN standard that defines a normalized traffic noise spectrum used in the evaluation and assessment of the acoustic performance of devices designed to reduce road traffic noise. As Part 3 of the EN 1793 series, it supplies a standardized reference noise spectrum that testers, manufacturers and authorities use when determining how effectively noise barriers, absorptive facings and other road traffic noise reducing devices perform.
Key topics and requirements
- Normalized traffic noise spectrum: Provides a reference distribution of noise energy across frequency for consistent performance evaluation.
- Purpose within test methods: Used as the standardized input or reference when applying the test procedures for acoustic performance described in the EN 1793 test method series.
- Comparability and reproducibility: Enables objective comparison between different noise-reducing devices by using the same reference spectrum across laboratories and field assessments.
- Scope limitation: Focuses on the reference spectrum used for evaluation and does not itself set pass/fail criteria or full installation requirements (these are covered in related parts of the EN 1793 suite).
Applications
EN 1793-3:1997 is practical for a range of stakeholders involved in road noise mitigation:
- Manufacturers of noise barriers, acoustic screens, absorptive panels and road-edge products use the standard spectrum to develop and validate product acoustic performance.
- Independent testing laboratories apply the normalized spectrum to carry out repeatable acoustic tests and produce comparable test reports.
- Highway and transport authorities refer to test results based on this standard when specifying, procuring or approving noise mitigation measures.
- Acoustic consultants and engineers use the reference spectrum for modeling, specifying mitigation measures, and preparing compliance documentation for roadway projects.
- Certification bodies and procurement teams rely on standardized test inputs to compare vendor claims and establish tender requirements.
Related standards
- EN 1793-3:1997 is part of the broader EN 1793 test method series for road traffic noise reducing devices. Other parts of the series address test procedures, measurement methods and performance classification used alongside the normalized spectrum.
Using EN 1793-3:1997 ensures uniformity in how traffic noise reducing devices are tested and reported, improving comparability and supporting evidence-based decisions in road noise mitigation projects.
