Full title and description

St ISO 717-1-2020 — Acoustics — Rating of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation. This international standard defines single-number quantities and procedures for rating airborne sound insulation of building elements (walls, floors, doors, windows, etc.) and gives rules for deriving those ratings from one-third-octave or octave band measurement results.

Abstract

The document (Part 1 of ISO 717) specifies single-number quantities for airborne sound insulation, provides spectrum adaptation terms to account for different noise spectra (e.g., indoor sources and traffic), and gives procedures for calculating the single-number ratings from measured results obtained in one-third-octave or octave bands (for example, in accordance with ISO 10140-2 and ISO 16283-1). It also notes additional evaluation steps for expressing uncertainty and guidance for expanded frequency ranges in annexes.

Scope

ISO 717-1:2020 applies to rating airborne sound insulation in buildings and of building elements. It covers the definition and calculation of single-number quantities used to characterise airborne sound insulation, the use of spectrum adaptation terms for different source spectra, and the procedures to derive these single-number ratings from one-third-octave or octave-band measurement results (measurement standards referenced include ISO 10140-2 for laboratory measurements and ISO 16283-1 for field measurements). Annex material addresses expanded frequency ranges and additional evaluation details.

Key topics and requirements

• Definition of single-number rating quantities for airborne sound insulation (to simplify specification and building-code requirements).
• Calculation rules from one-third-octave and octave-band measurement data (frequency ranges and reference curves specified).
• Spectrum adaptation terms (e.g., C and Ctr style terms) to account for different noise spectra (interior sources, traffic, etc.).
• Reference to and use of measurement standards such as ISO 10140-2 (laboratory) and ISO 16283-1 (field) when deriving ratings.
• Procedures for expressing uncertainty and optional finer-step evaluations (0.1 dB steps indicated for uncertainty expression).

Typical use and users

Used by acousticians, building designers, architects, test laboratories, building code authorities, product manufacturers (doors, windows, partitions, floors), and certification bodies to specify, test, rate, compare and regulate airborne sound insulation performance for buildings and building elements.

Related standards

Commonly used together with the ISO 10140 series (laboratory measurement of airborne sound insulation) and the ISO 16283 series (field measurement procedures). Part 2 of the ISO 717 series covers impact sound insulation (ISO 717-2:2020). National and regional adoptions exist (for example EN ISO 717-1 and national standards bodies’ harmonized editions).

FAQ

Q: What is this standard?

A: ISO 717-1:2020 is the international standard that defines single-number quantities and procedures for rating airborne sound insulation of buildings and building elements. It provides a common basis for specifying and comparing airborne sound insulation performance.

Q: What does it cover?

A: It covers the definition and calculation of airborne sound insulation single-number ratings from one-third-octave or octave-band measurement results, includes spectrum adaptation terms for different source spectra, references appropriate measurement standards (ISO 10140-2, ISO 16283-1), and gives guidance on uncertainty and extended frequency-range evaluations.

Q: Who typically uses it?

A: Acoustical consultants, test laboratories, architects, product manufacturers, regulatory authorities and certification bodies use it to specify, measure, report and regulate airborne sound insulation performance in buildings and building components.

Q: Is it current or superseded?

A: ISO 717-1:2020 is the current published edition (published December 2020). It superseded earlier editions including ISO 717-1:2013 and older versions; the earlier 2013 edition is withdrawn. The standard is subject to periodic review.

Q: Is it part of a series?

A: Yes — ISO 717 is a multi-part series. Part 1 addresses airborne sound insulation (this standard) and Part 2 addresses impact sound insulation (ISO 717-2:2020); the series is intended to provide consistent rating methods for different types of sound insulation.

Q: What are the key keywords?

A: Airborne sound insulation, single-number rating, spectrum adaptation term, acoustics, ISO 10140, ISO 16283, building elements, rating procedure.
