Acoustics - Measurement of room acoustic parameters - Part 3: Open plan offices (ISO 3382-3:2022)
This document specifies a method for the measurement of room acoustic parameters in unoccupied open-plan offices. It specifies measurement procedures, the apparatus needed, the coverage required, the method for evaluating the data, and the presentation of the test report.
This document describes a group of single-number quantities indicating the room acoustic performance of an open-plan office in a condition when one person is speaking. They focus on spatial decay of speech while the quantities in ISO 3382-2 focus on temporal decay of sound.
Akustik - Messung von Parametern der Raumakustik - Teil 3: Großraumbüros (ISO 3382-3:2022)
Dieses Dokument legt ein Verfahren zur Messung von Parametern der Raumakustik in unbesetzten Großraum¬büros fest. Festgelegt werden Messverfahren, die benötigte Prüfeinrichtung, die erforderliche Messpunkt¬dichte, das Verfahren zur Bewertung der Daten und die Angabe des Prüfberichts.
Dieses Dokument beschreibt eine Gruppe von Einzahlwerten, welche die raumakustischen Eigenschaften eines Großraumbüros in einem Zustand, bei dem eine Person spricht, angeben. Schwerpunkt dieser Einzahl¬werte ist das räumliche Abklingen von Sprache, während sich die Größen in ISO 3382 2 auf das zeitliche Abklingen von Schall konzentrieren.
Acoustique - Mesurage des paramètres acoustiques des salles - Partie 3: Bureaux ouverts (ISO 3382-3:2022)
Le présent document spécifie une méthode de mesurage des paramètres acoustiques des salles dans des bureaux ouverts non occupés. Il décrit les modes opératoires de mesurage, l’appareillage nécessaire, la couverture requise, la méthode d’évaluation des données et la présentation du rapport d’essai.
Le présent document décrit un groupe de grandeurs exprimées en valeurs uniques indiquant la performance acoustique d’un bureau ouvert lorsqu’une personne parle. Ces grandeurs sont basées sur le taux de décroissance spatiale de la parole, tandis que celles de l’ISO 3382-2 concernent le taux de décroissance temporelle du son.
Akustika - Merjenje parametrov prostorske akustike - 3. del: Velike odprte pisarne (ISO 3382-3:2022)
Ta dokument določa metodo za merjenje parametrov prostorske akustike v praznih
velikih odprtih pisarnah. Določa merilne postopke, potrebne naprave, zahtevano pokritost
ter metodo za vrednotenje podatkov in predstavitev poročila o preskusu.
Ta dokument opisuje skupino enoštevilskih vrednosti, ki označujejo prostorske akustične lastnosti velike odprte pisarne, kadar v njej govori ena oseba. Osredotočajo se na prostorski razpad govora, medtem ko se vrednosti v standardu ISO 3382-2 osredotočajo na časovni razpad zvoka.

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/iso/foreword.html.
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 products and buildings, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 3382-3:2012), which has been technically
revised. The main changes compared to the previous edition are as follows:
— new single-number quantity, comfort distance, added, and privacy distance removed;
— sole use of omnidirectional sound source in all measurement phases emphasized;
— definitions (Clause 3), measurement conditions (Clause 4), and determination of single-number
values (Clause 5) clarified;
— use of impulse response method better described and a new Annex B added;
— Clause 6 “Precision” and an informative Annex D were added;
— STI is determined in conformity with IEC 60268-16 using weighting factors α and β for male gender;
