Acoustics - Rating of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation (ISO 717-1:2013)
This part of ISO 717:
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;
c) gives rules for determining these quantities from the results of measurements carried out in onethird- octave or octave bands in accordance with ISO 10140-2, ISO 140-4, and ISO 140-5. The single-number quantities in accordance with this part of ISO 717 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, single-number quantities should be 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.
Akustik - Bewertung der Schalldämmung in Gebäuden und von Bauteilen - Teil 1: Luftschalldämmung (ISO 717-1:2013)
Dieser Teil von ISO 717
a) legt Einzahlangaben für die Luftschalldämmung in Gebäuden und von Bauteilen wie Wänden, Decken, Türen und Fenstern fest;
b) berücksichtigt die verschiedenen Schallpegelspektren verschiedener Geräuschquellen wie die für Geräusche in einem Gebäude und die für Verkehrsgeräusche außerhalb eines Gebäudes;
c) enthält Regeln für die Ermittlung dieser Einzahlangaben aus den Ergebnissen von Messungen in Terz oder Oktavbändern nach ISO 10140 2, ISO 140 4 und ISO 140 5.
Die Einzahlangaben nach diesem Teil von ISO 717 sind für die Bewertung der Luftschalldämmung und für die Vereinfachung der Formulierung von akustischen Anforderungen in Bauvorschriften vorgesehen. Zum Zwecke der Angabe der Unsicherheit ist die Ermittlung einer zusätzlichen Einzahlangabe in 1/10-dB-Schritten enthalten (ausgenommen sind die Spektrum Anpassungswerte). Die erforderlichen numerischen Werte dieser Einzahlangaben werden für verschiedene Bedürfnisse festgelegt. Grundlage für die Einzahlangaben sind Ergebnisse aus Messungen in Terzbändern oder in Oktavbändern.
Bezüglich der Messungen in Prüfständen nach ISO 10140 sollten Einzahlangaben nur auf der Grundlage von Terzbändern berechnet werden.
Die Bewertung der Ergebnisse von Messungen über einen erweiterten Frequenzbereich wird im Anhang B behandelt.
Acoustique - Évaluation de l'isolement acoustique des immeubles et des éléments de construction - Partie 1: Isolement aux bruits aériens (ISO 717-1:2013)
L'ISO 717-1:2013
a) définit des valeurs uniques de l'isolement aux bruits aériens des immeubles et des éléments de construction tels que murs, planchers, portes et fenêtres,
b) prend en considération les différents spectres sonores de sources de bruit variées telles que des sources de bruit à l'intérieur d'un immeuble et du trafic à l'extérieur d'un immeuble, et
c) spécifie des règles de détermination de ces valeurs d'après les résultats de mesurages effectués dans des bandes de fréquences d'une largeur de tiers d'octave ou d'octave conformément à l'ISO 10140‑2, l'ISO 140‑4 et l'ISO 140‑5.
Les valeurs uniques spécifiées dans l'ISO 717-1:2013 sont destinées à indiquer la qualité de l'isolement aux bruits aériens et à faciliter l'énoncé des exigences en matière d'acoustique dans les règles techniques de la construction. Une évaluation unique complémentaire par pas de 0,1 dB est indiquée pour exprimer l'incertitude (sauf pour les termes d'adaptation à un spectre). Les valeurs numériques requises pour ces valeurs uniques sont spécifiées suivant les besoins. Les valeurs uniques sont basées sur des résultats de mesurages effectués par bandes de fréquences de tiers d'octave ou par bandes d'octave.
En ce qui concerne les mesures en laboratoire effectuées selon l'ISO 10140, il convient de calculer les valeurs uniques sur la base des bandes de tiers d'octave seulement.
L'évaluation des résultats des mesurages effectués dans une gamme étendue de fréquences est abordée dans une annexe.
Akustika - Vrednotenje zvočne izolirnosti v stavbah in zvočne izolirnosti gradbenih elementov - 1. del: Izolirnost pred zvokom v zraku (ISO 717-1:2013)
Ta del standarda ISO 717:
a) določa enoštevilčne vrednosti za izolirnost pred zvokom v zraku v stavbah in izolirnost gradbenih elementov, kot so stene, tla, vrata in okna;
b) upošteva različne spektre zvočnih ravni različnih virov hrupa, kot so viri hrupa v stavbi in hrup prometa zunaj nje;
c) določa pravila za opredeljevanje teh količin na podlagi rezultatov meritev, opravljenih v pasovih ene tretjine oktave ali oktavnih pasovih v skladu s standardi ISO 10140-2, ISO 140-4 in ISO 140-5. Enoštevilčne vrednosti v skladu s tem delom standarda ISO 717 so namenjene vrednotenju izolirnosti pred zvokom v zraku in poenostavitvi formulacije akustičnih zahtev v gradbenih predpisih. Dodatna ocena enoštevilčne vrednosti v korakih po 0,1 dB je navedena za izražanje merilne negotovosti (razen faktorjev prilagoditve spektra). Zahtevane številske vrednosti enoštevilčnih količin so opredeljene glede na različne potrebe. Enoštevilčne vrednosti temeljijo na rezultatih meritev v pasovih ene tretjine oktave ali oktavnih pasovih. Za laboratorijske meritve, opravljene v skladu s standardom ISO 10140, naj bi se enoštevilčne vrednosti izračunale izključno s pasovi ene tretjine oktave. Vrednotenje rezultatov meritev, opravljenih v večjem frekvenčnem obsegu, je obravnavano v dodatku B.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 717-1 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics.
This third edition cancels and replaces the second edition (ISO 717-1:1996), which has been technically
revised. It also incorporates the Amendment ISO 717-1:1996/Amd. 1:2006.
The purpose of this revised version is to:
— allow weighting steps of 0,1 dB to be used for expression of uncertainty;
— update references.
ISO 717 consists of the following parts, under the general title Acoustics — Rating of sound insulation in
buildings and of building elements:
— Part 1: Airborne sound insulation
— Part 2: Impact 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, ISO 140-4, and ISO 140-5. The purpose of this part of ISO 717 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 717-1:2013(E)
Acoustics — Rating of sound insulation in buildings and of
building elements —
Part 1:
Airborne sound insulation
1 Scope
This part of ISO 717:
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;
c) gives rules for determining these quantities from the results of measurements carried out in one-
third-octave or octave bands in accordance with ISO 10140-2, ISO 140-4, and ISO 140-5.
The single-number quantities in accordance with this part of ISO 717 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, single-number quantities should be
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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 717-1 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
This second edition cancels and replaces the first edition (ISO 717-1:1996+Amd 1:2004), which has been
technically revised.
ISO 717 consists of the following parts, under the general title Acoustics — Rating of sound insulation in
buildings and of building elements:
⎯ Part 1: Airborne sound insulation
⎯ Part 2: Impact 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, ISO 140-4, and ISO 140-5. The purpose of this part of ISO 717 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.
The purpose of this revised version is to
• to allow weighting steps of 0.1 dB to be used for expression of uncertainty,
• to include the existing Amendment 1 of ISO 717, and
• to update references.
References to standards which provide data for single-number evaluation are meant to be examples and therefore are not
complete.

DRAFT INTERNATIONAL STANDARD ISO/DIS 717-1
Acoustics — Rating of sound insulation in buildings and of
building elements — Part 1: Airborne sound insulation
1 Scope
This part of ISO 717
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 in accordance with ISO 10140-2, ISO 140-4 and ISO 140-5.
The single-number quantities in accordance with this part of ISO 717 are intended for rating the airborne
sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional
single-number evaluation in 1/10-dB-steps 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, single-number quantities should be
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 ISO 10140-2, ISO 140-4 and ISO 140-5 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.
4.2 Reference values
The set of reference values used for comparison with measurement results shall be as given in table 3. The
reference curves are shown in Figure 1 and Figure 2.
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.
