Acoustics - Rating of sound insulation in buildings and of building elements - Part 2: Impact sound insulation (ISO 717-2:2020)
This document
a) defines single-number quantities for impact sound insulation in buildings and of floors,
b) gives rules for determining these quantities from the results of measurements carried out in one-third-octave bands in accordance with ISO 10140-3 and ISO 16283-2, and in octave bands in accordance with that option in ISO 16283-2 for field measurements only,
c) defines single-number quantities for the impact sound reduction of floor coverings and floating floors calculated from the results of measurements carried out in accordance with ISO 10140-3, and
d) specifies a procedure for evaluating the weighted reduction in impact sound pressure level by floor coverings on lightweight floors.
The single-number quantities in accordance with this document are intended for rating impact 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 where it is needed for the expression of uncertainty (except for spectrum adaptation terms). Numerical values of the single-number quantities are specified where required for calculations.
The rating of measurements over an enlarged frequency range is given in Annex A.
A method for obtaining single-number quantities for bare heavy floors according to their performance in combination with floor coverings is given in Annex B.
Example calculations of single-number quantities are given in Annex C.
The rating of measurements with a heavy and soft impact source (rubber ball) is given in Annex D.
Akustik - Bewertung der Schalldämmung in Gebäuden und von Bauteilen - Teil 2: Trittschalldämmung (ISO 717-2:2020)
Dieses Dokument
a) legt Einzahlangaben für die Trittschalldämmung in Gebäuden und von Decken fest,
b) enthält Regeln für die Ermittlung dieser Einzahlangaben aus den Ergebnissen von Messungen in Terzbändern nach ISO 10140 3 und ISO 16283 2 und in Oktavbändern entsprechend der zutreffenden Option in ISO 16283 2 ausschließlich für Messungen in Gebäuden,
c) legt Einzahlangaben für die Trittschallminderung durch Deckenauflagen und schwimmende Estriche fest, die aus den Ergebnissen von Messungen nach ISO 10140 3 berechnet wurden, und
d) legt ein Verfahren zur Ermittlung der bewerteten Trittschallpegelminderung durch Deckenauflagen auf leichten Decken fest.
Die Einzahlangaben nach diesem Dokument sind für die Bewertung der Trittschalldämmung und für die Vereinfachung der Formulierung von akustischen Anforderungen in Bauvorschriften vorgesehen. Wenn erforderlich, ist zum Zwecke der Angabe der Unsicherheit die Ermittlung einer zusätzlichen Einzahlangabe in 0,1 dB-Schritten enthalten (ausgenommen sind die Spektrum-Anpassungswerte). Wenn für Berechnungen erforderlich, werden numerische Werte der Einzahlangaben für verschiedene Bedürfnisse festgelegt.
Die Bewertung der Messungen über einen erweiterten Frequenzbereich wird in Anhang A angegeben.
Ein Verfahren zur Bestimmung von Einzahlangaben für massive Rohdecken entsprechend ihrer Leistung in Kombination mit Deckenauflagen wird in Anhang B angegeben.
Beispielberechnungen von Einzahlangaben werden in Anhang C angegeben.
Die Bewertung der Messungen mit einer schweren und weichen Trittschallquelle (Gummiball) ist in Anhang D angegeben.
Acoustique - Évaluation de l'isolement acoustique des immeubles et des éléments de construction - Partie 2: Protection contre le bruit de choc (ISO 717-2:2020)
Le présent document:
a) définit des valeurs uniques de l'isolement acoustique des immeubles et des planchers au bruit de choc;
b) spécifie des règles de détermination de ces valeurs d'après les résultats de mesures effectuées dans des bandes de fréquences de tiers d'octave conformément à l'ISO 10140-3 et à l'ISO 16283-2, et dans des bandes de fréquences d'octave conformément à l'ISO 16283-2 pour des mesures sur site seulement;
c) définit des valeurs uniques de la réduction du bruit de choc par les revêtements de sol et les planchers flottants calculées d'après les résultats de mesures effectuées conformément à l'ISO 10140-3;
d) spécifie un mode opératoire d'évaluation de la réduction du niveau du bruit de choc pondéré par les revêtements de sol sur des planchers légers.
Les valeurs uniques spécifiées dans le présent document sont destinées à indiquer la qualité de l'isolement acoustique aux bruits de choc 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 lorsque cela est nécessaire pour exprimer l'incertitude (sauf pour les termes d'adaptation à un spectre). Les valeurs numériques de ces valeurs uniques sont spécifiées lorsque cela est nécessaire pour les calculs.
L'évaluation des mesures sur une gamme étendue de fréquences est traitée à l'Annexe A.
Un procédé d'obtention des valeurs uniques pour les planchers nus lourds, selon leur performance acoustique lorsqu'ils sont revêtus de revêtement de sol, figure à l'Annexe B.
Des exemples de calcul de valeurs uniques figurent à l'Annexe C.
L'évaluation des mesures avec une source de choc lourd et mou (balle en caoutchouc) est traitée à l'Annexe D.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2,
Building acoustics, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 126, Acoustic properties of building elements and of buildings, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 717-2:2013), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— A new Annex D with a method for rating heavy/soft impact sound insulation using an A-weighted
maximum impact sound pressure level.
A list of all parts in the ISO 717 series can be found on the ISO website.
