Full title and description

St ISO TS 12913-3-2025 — Acoustics — Soundscape — Part 3: Data analysis. This Technical Specification provides requirements and guidance for analysing in situ soundscape data collected according to ISO/TS 12913-2, with emphasis on statistical treatment, linking physical/psychoacoustic indicators to perceptual responses, spatial analysis and reporting of results for research, practice and policy.

Abstract

This document defines recommended methods and supporting information for processing and analysing soundscape data gathered in the field. It covers data preparation, quality checks, statistical and modelling approaches to relate acoustic and psychoacoustic indicators (for example loudness, sharpness, roughness) to perceptual evaluations, and options for spatial analysis and visualisation to support planning and management of acoustic environments.

Scope

This Technical Specification provides requirements and supporting information on the analysis of soundscape data collected in situ using methods specified in ISO/TS 12913-2. It addresses data cleaning, recommended acoustic and psychoacoustic indicators, approaches to statistical analysis and modelling, techniques for relating measured and derived indicators to perceptual survey responses, and guidance on spatial mapping and presentation of results for decision-making.

Key topics and requirements

• Data preparation and quality assurance for in situ soundscape datasets (including metadata requirements).
• Recommended acoustic and psychoacoustic indicators (e.g., indicators such as loudness, sharpness, roughness) and how to compute or derive them from measurements.
• Statistical analysis and modelling methods to relate physical/psychoacoustic indicators to perceptual ratings and contextual variables.
• Guidance on spatial analysis and GIS-based mapping of perceptual patterns, tranquil areas and hotspots.
• Reporting formats, visualization best practices and reproducibility considerations for research and applied studies.

Typical use and users

Researchers in acoustics and environmental psychology, acoustic consultants, urban planners and designers, public health practitioners, local authorities and policymakers use this specification to analyse field-collected soundscape data, interpret perceptual responses in context, and produce evidence-based recommendations for soundscape planning and interventions.
