Acoustics - Laboratory and field measurement of the flanking transmission for airborne, impact and building service equipment sound between adjoining rooms - Part 5: Radiation efficiencies of building elements (ISO 10848-5:2020)

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one
or several building components. This document considers only laboratory measurements.
This part of ISO 10848 specifies measurement methods to be performed in a laboratory to characterize
the acoustic radiation of a building element when mechanically or acoustically excited. The measured
quantities can be used to compare products, or to express a requirement, or as input data for prediction
methods, such as ISO 12354-1 and -2.

Akustik - Messung der Flankenübertragung von Luftschall und Trittschall zwischen benachbarten Räumen im Prüfstand - Teil 5: Strahlungswirksamkeit von Bauelementen (ISO 10848-5:2020)

Dieses Dokument legt Messverfahren zur Charakterisierung der akustischen Abstrahlung eines Bauteils im Prüfstand fest, wenn es direkt von einer Luft  oder Körperschallquelle angeregt wird. Er gilt für ein  und zweischalige Bauteile (siehe ISO 12354 1:2017, Anhang F, F2). Die gemessenen Größen können als Eingabedaten für Berechnungsverfahren wie in ISO 12354 1 und ISO 12354 2 angegeben verwendet werden, um Produkte zu vergleichen oder um eine Anforderung festzulegen.

Le présent document spécifie les méthodes de mesure pour la caractérisation en laboratoire du rayonnement acoustique d'un élément de construction lorsqu'il est directement excité par une source aérienne ou solidienne. Il est applicable aux éléments de paroi simple ou double (voir l'ISO 12354-1:2017, Annexe F, F2). La grandeur mesurée peut être utilisée comme donnée d'entrée des méthodes de prévision telles que l'ISO 12354-1 et l'ISO 12354-2, pour comparer des produits ou pour exprimer une exigence.

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.

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

ISO 10848-5:2020(E)
Introduction

ISO 10848 (all parts) specifies laboratory and field measurement methods to characterize the flanking

transmission of one or several building components.

This document describes the measurement of the radiation efficiency of an element using structure-

borne excitation and/or acoustical excitation. Both these radiation efficiencies are required to estimate

the sound reduction index due to resonant transmission only, according to ISO 12354-1:2017, Annex B.

For Type B elements as defined in ISO 10848-1 and ISO 12354-1, the radiation efficiency of an element

using structure-borne excitation is required to calculate flanking transmission. It is also required to

estimate adaptation terms used in predicting service equipment sound according to EN 12354-5.

Radiation efficiencies of building elements
1  Scope

This document specifies measurement methods to characterize in the laboratory the acoustic radiation

of a building element when it is directly excited by an airborne or structure-borne source. It is applicable

to single-leaf and double-leaf elements (see ISO 12354-1:2017 Annex F, F2). The measured quantity

can be used as input data for prediction methods, such as ISO 12354-1 and ISO 12354-2, to compare

products, or to express a requirement.
