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)

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.

Akustik - Messung der Flankenübertragung von Luftschall, Trittschall und Schall von gebäudetechnischen Anlagen zwischen benachbarten Räumen im Prüfstand und am Bau - Teil 5: Abstrahlgrade 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.

Acoustique - Mesurage en laboratoire et sur site des transmissions latérales du bruit aérien, des bruits de choc et du bruit d’équipement technique de bâtiment entre des pièces adjacentes - Partie 5: Efficacité de rayonnement des éléments de construction (ISO 10848-5:2020)

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.
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
