General Information
Relations
Overview
EN ISO 717-1:2020 - "Acoustics - Rating of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation" (ISO 717-1:2020) standardizes how frequency-dependent airborne sound insulation results are converted into single-number ratings. It defines the single-number quantity (the value of the reference curve at 500 Hz after shifting) and associated spectrum adaptation terms to reflect different noise spectra (e.g., internal building sources vs. external traffic). The standard supports both laboratory and field measurement results and is intended to simplify acoustical specifications in building codes and product requirements.
Key topics and requirements
- Single-number quantities: Defines the method to obtain a single-number airborne sound insulation rating from octave or one-third-octave band data.
- Reference and calculation method: The single-number rating is derived by shifting a reference curve; the reference value at 500 Hz is used as the rating.
- Spectrum adaptation terms (C and Ctr): Two spectrum adaptation terms are specified to account for typical sound spectra (internal and external/traffic). These are added to the single-number rating when relevant.
- Measurement bases and frequency ranges:
- One-third-octave bands: 100 Hz to 3 150 Hz (required for laboratory measurements per ISO 10140-2).
- Octave bands: 125 Hz to 2 000 Hz (allowed for some applications).
- Annex B addresses rating using an enlarged frequency range.
- Uncertainty expression: An optional more precise single-number evaluation in steps of 0.1 dB is provided for expressing uncertainty (except for spectrum adaptation terms).
- Applicable test standards: Rules provided assume band data from standards such as ISO 10140-2 (laboratory) and ISO 16283-1 (field).
Applications and users
EN ISO 717-1:2020 is used to:
- Rate walls, floors, doors, windows and other building elements for airborne sound insulation.

Introduction
Methods of measurement of airborne sound insulation of building elements and in buildings have been
standardized e.g. in ISO 10140-2 and ISO 16283-1. The purpose of this document is to standardize a
method whereby the frequency-dependent values of airborne sound insulation can be converted into a
single number characterizing the acoustical performance.
References to standards which provide data for single-number evaluation are meant to be examples
and therefore are not complete.
INTERNATIONAL STANDARD ISO 717-1:2020(E)
Acoustics — Rating of sound insulation in buildings and of
building elements —
Part 1:
Airborne sound insulation
1 Scope
This document
a) defines single-number quantities for airborne sound insulation in buildings and of building
elements such as walls, floors, doors, and windows,
b) takes into consideration the different sound level spectra of various noise sources such as noise
sources inside a building and traffic outside a building, and
c) gives rules for determining these quantities from the results of measurements carried out in one-
third-octave or octave bands for example in accordance with ISO 10140-2 and ISO 16283-1.
The single-number quantities in accordance with this document are intended for rating airborne
sound insulation and for simplifying the formulation of acoustical requirements in building codes. An
additional single-number evaluation in steps of 0,1 dB is indicated for the expression of uncertainty
(except for spectrum adaptation terms). The required numerical values of the single-number quantities
are specified according to varying needs. The single-number quantities are based on results of
measurements in one-third-octave bands or octave bands.
For laboratory measurements made in accordance with ISO 10140-2, single-number quantities are
calculated using one-third-octave bands only.
The rating of results of measurements carried out over an enlarged frequency range is dealt with in
Annex B.

4 Procedure for evaluating single-number quantities
4.1 General
The values obtained in accordance with e.g. ISO 10140-2 and ISO 16283-1 are compared with reference
values (see 4.2) at the frequencies of measurement within the range 100 Hz to 3 150 Hz for one-third-
octave bands and 125 Hz to 2 000 Hz for octave bands.
The comparison shall be carried out as specified in 4.4.
Furthermore, two spectrum adaptation terms shall be calculated (see 4.5) based on two typical spectra
within the frequency range as quoted above. These two terms may optionally be supplemented by
additional spectrum adaptation terms covering (if need be and if measured data are available) a wider
frequency range between 50 Hz and 5 000 Hz.

4.3 Sound spectra
The set of sound spectra in one-third-octave bands and octave bands to calculate the spectrum
adaptation terms shall be as given in Table 4 and shown in Figure 3 and Figure 4. The spectra are
A-weighted and the overall spectrum level is normalized to 0 dB.
4.4 Method of comparison
To evaluate the results of a sound insulation measurement in one-third-octave bands (or octave bands),
1)
the measurement data shall be given to one decimal place . Shift the relevant reference curve in
increments of 1 dB (0,1 dB for the expression of uncertainty) towards the measured curve until the sum
of unfavourable deviations is as large as possible, but not more than 32,0 dB (measurement in 16 one-
third-octave bands) or 10,0 dB (measurement in 5 octave bands).
1) ISO 10140-2 and ISO 16283-1 state that the results shall be reported “to one decimal place”. However, if the
octave or one-third-octave values have been reported with more than one decimal digit, the values should be reduced
to one decimal place before use in the calculation of the single number rating. This is done by taking the value in
tenths of a decibel closest to the reported values: XX,XYZ ZZ . is rounded to XX,X if Y is less than 5 and to XX,X + 0,1
if Y is equal to or greater than 5. Software developers should ensure that this reduction applies to the true input
values and not only to the displayed precision (as shown on the screen or printed on paper). Generally this can be
implemented by the following sequence of instructions: multiply the (positive) number XX,XYZ ZZ . by 10 and add

The SIST EN ISO 717-1:2021 standard provides a comprehensive and structured approach to the rating of airborne sound insulation in buildings and building elements. This document is critical for establishing single-number quantities that succinctly represent the sound insulation properties of various components such as walls, floors, doors, and windows. By defining these quantities, the standard facilitates a consistent method for assessing and denoting the effectiveness of sound insulation in a practical manner. One of the significant strengths of this standard is its consideration of diverse sound level spectra from various noise sources. By accounting for both internal noise sources and external traffic noise, it ensures that the airborne sound insulation ratings are relevant in real-world scenarios. This alignment with actual environmental conditions enhances the utility of the standard, making it highly applicable for architects, builders, and acousticians. Furthermore, the document outlines precise methodologies for determining the single-number quantities based on measurement results from one-third-octave or octave bands, as specified in ISO 10140-2 and ISO 16283-1.

The inclusion of the additional single-number evaluation expressed in 0.1 dB increments to account for uncertainty underscores the attention to detail and precision that the standard promotes. Moreover, the standard is adaptable to various needs by specifying the required numerical values of the single-number quantities, allowing stakeholders to apply it across different regulatory frameworks and building codes. This adaptability aids in simplifying the formulation of acoustical requirements, making the standard relevant not just for compliance but also for enhancing building designs. Lastly, the treatment of results from measurements conducted across an expanded frequency range in Annex B adds another layer of depth to the standard, enabling users to comprehensively assess sound insulation performance. Overall, SIST EN ISO 717-1:2021 stands out as a fundamental document that significantly contributes to the field of acoustics and sound insulation, ensuring that high standards are met in building design and construction.

Cela permet d'obtenir une évaluation plus précise et réaliste de l'isolation acoustique, en tenant compte des conditions réelles d'utilisation des espaces. De plus, les règles définies pour déterminer ces quantités sont basées sur des mesures effectuées dans des bandes d'octaves ou de tiers d’octave, ce qui garantir une méthodologie robuste et largement acceptée, conforme à des normes précédemment établies comme ISO 10140-2 et ISO 16283-1. La norme fournit également une évaluation supplémentaire basée sur des increments de 0,1 dB pour exprimer l'incertitude, excepté pour les termes d'adaptation spectrale. Cela montre l'engagement de la norme envers la précision et la rigueur scientifique, ce qui est essentiel pour les professionnels du secteur. L'aspect le plus pertinent de la norme SIST EN ISO 717-1:2021 est son applicabilité à l'élaboration de codes du bâtiment qui intègrent des exigences acoustiques. En simplifiant le processus d’évaluation, cette norme contribue à une intégration plus fluide des exigences d'isolation acoustique dans les projets de construction, ce qui est crucial pour garantir un environnement bâti confortable et fonctionnel. En somme, la norme SIST EN ISO 717-1:2021 se distingue par sa définition claire des critères d'évaluation, sa prise en compte des complexités acoustiques et sa contribution à l'élaboration de référentiels normatifs. Ces atouts en font un document de référence incontournable pour les professionnels du bâtiment soucieux d’optimiser l’isolation acoustique de leurs constructions.
SIST EN ISO 717-1:2021は、建物および建物要素の空気音の遮音評価に関する標準であり、その内容は非常に広範で重要です。この標準は、壁、床、ドア、窓などの構造要素に対して、空気音遮音の単一数値量を定義しています。これにより、建物の音響要件を簡素化し、建築基準法における遮音要求の策定が容易になります。 この標準の強みは、様々な音源の異なる音圧レベルスペクトルを考慮している点です。建物内の騒音源や外部の交通騒音など、多様な音源の影響を評価することができ、より実践的な音響評価が可能となります。また、ISO 10140-2およびISO 16283-1に従った測定結果からこれらの単一数値量を導出するためのルールが示されており、測定方法の明確化に寄与しています。 さらに、0.1 dBのステップでの不確かさの表現が可能であることも、この標準の重要な特徴です。これは、より精密な評価を行う上での信頼性を高め、測定結果の正確性を確保します。特に、ISO 10140-2に従った実験室での測定においては、三分の一オクターブバンドを使用して単一数値量が計算されるため、精度が高い評価が期待できます。 最後に、拡張された周波数範囲にわたる測定結果の評価については、附属書Bで詳しく扱われており、音響設計の多様なニーズに応えることができます。このように、SIST EN ISO 717-1:2021は、建物の空気音遮音評価の標準としての重要性と関連性を強く持っていると言えます。
Die Norm SIST EN ISO 717-1:2021, die sich mit der Akustik befasst, legt einen klaren Rahmen für die Bewertung der Luftschalldämmung in Gebäuden und von Baukonstruktionen wie Wänden, Böden, Türen und Fenstern fest. Ein wesentlicher Schwerpunkt dieser Norm liegt auf der Definition von Einzelzahlen, die eine vereinfachte Darstellung der Luftschalldämmung ermöglichen. Diese Einzelwerte sind besonders relevant, da sie nicht nur für die Bewertung der Akustik in Gebäuden von Bedeutung sind, sondern auch für die Formulierung von akustischen Anforderungen in Bauvorschriften, was die Anwendung in der Praxis erleichtert. Die Norm berücksichtigt dabei die unterschiedlichen Schallpegel-Spektren verschiedener Lärmquellen, sowohl innerhalb als auch außerhalb von Gebäuden. Dies zeigt die Vielseitigkeit des Dokuments und seine Fähigkeit, unterschiedliche akustische Bedingungen zu integrieren. Interessant ist zudem, dass die Norm Regeln zur Bestimmung dieser Einzelzahlen gibt, die auf den Ergebnissen von Messungen basieren, die innerhalb von einem Drittel Oktav- oder Oktavbändern gemäß ISO 10140-2 und ISO 16283-1 durchgeführt wurden. Diese Methodologie sichert die Konsistenz und Verlässlichkeit der ermittelten Daten. Ein zusätzliches Merkmal der Norm ist die Angabe einer Einzelbewertung in Schritten von 0,1 dB, um Unsicherheiten präzise auszudrücken. Dies ist besonders nützlich, da es Planern und Ingenieuren ermöglicht, eine differenzierte Analyse der Schalldämmung vorzunehmen. Die Quantifizierung von Schallpegeln in unterschiedlichen Frequenzbereichen, wie in Anhang B behandelt, erweitert das Anwendungsspektrum und bietet tiefere Einblicke in die akustischen Eigenschaften von Baukonstruktionen. Insgesamt stellt die SIST EN ISO 717-1:2021 einen bedeutenden Fortschritt in der Akustikdarstellung dar, indem sie klare und präzise Quantifizierungen für die Luftschalldämmung bereitstellt und damit ein wichtiges Instrument für Architekten, Ingenieure und Bauplaner zur Verfügung stellt. Die Relevanz dieser Norm in der heutigen Baupraxis kann nicht unterschätzt werden, da sie eine essentielle Grundlage für die Einhaltung akustischer Standards in Neubauten sowie Renovierungen bildet.
