Full title and description

Acoustics — Description, measurement and assessment of environmental noise — Part 1: Basic quantities and assessment procedures. This international standard defines the basic acoustic quantities, introduces the concept of rating levels, and gives procedures and guidance for assessing environmental (community) noise and estimating long‑term community response to noise exposure.

Abstract

ISO 1996-1:2016 specifies the fundamental quantities to be used when describing noise in community environments, describes basic assessment procedures and methods to assess environmental noise, and gives guidance for predicting potential annoyance responses to long‑term exposure from different types of environmental noise. The standard addresses single and combined sound sources and allows adjustments for special characteristics such as impulsiveness, tonality and low‑frequency content. It does not set numerical noise limits.

Scope

ISO 1996-1:2016 covers the definition and use of basic acoustic quantities for describing environmental (community) noise and provides assessment procedures for long‑term noise exposure. It applies to noise from various sources (road, rail, aircraft, industrial and other community sources), singly or in combination, and is intended for areas where people reside and related long‑term land uses. The standard provides methods to produce rating levels by applying adjustments for special characteristics of sounds and gives guidance on estimating long‑term community annoyance; it does not prescribe noise limits.

Key topics and requirements

• Definitions of basic acoustic quantities used for environmental noise (e.g., equivalent continuous sound pressure level, maximum sound pressure level and other level descriptors).
• Introduction and use of rating levels: applying adjustments to physical measurements or predictions to account for special sound characteristics.
• Guidance on assessing combined sound sources and separating contributions when required.
• Procedures and considerations for predicting long‑term community response (annoyance) to environmental noise exposure.
• Consideration of special characteristics: impulsiveness, tonality and low‑frequency content and source‑specific characteristics (road, other transport, industrial).
• Clarification that the standard provides assessment methodology and does not set regulatory limit values.

Typical use and users

Practitioners and organisations using ISO 1996-1:2016 include environmental acousticians, noise consultants, urban and transport planners, local and national regulatory authorities, environmental impact assessment (EIA) practitioners, and academic researchers. Typical applications are noise inventories, impact assessments for planning and development, guidance for mitigation strategy development, and supporting policy and regulation development where harmonised description and assessment procedures are required.

Related standards

ISO 1996-1 is part of the ISO 1996 series on environmental noise. Closely related standards include ISO 1996-2 (determination of sound pressure levels and procedures for determining environmental noise levels) and other ISO/TC 43 publications dealing with environmental noise measurement and prediction. Standards on outdoor sound propagation (for example those dealing with attenuation during propagation) are commonly used alongside ISO 1996-1 in practical assessments.
