DIN EN ISO 15186-2
Acoustics - Measurement of sound insulation in buildings and of building elements using sound intensity - Part 2: Field measurements (ISO 15186-2:2003); German version EN ISO 15186-2:2010

Title (German)

Akustik - Bestimmung der Schalldämmung in Gebäuden und von Bauteilen aus Schallintensitätsmessungen - Teil 2: Messungen am Bau (ISO 15186-2:2003); Deutsche Fassung EN ISO 15186-2:2010

Overview

The document specifies a sound intensity method to determine the sound insulation of walls, floors, windows and small building elements by field measurements. The method is intended for measurements that have to be made in the presence of flanking transmission. It can be used to provide sound power data for diagnostic analysis of flanking transmission or to measure flanking sound insulation parameters. The document can be used by laboratories that can not satisfy the requirements of ISO 15186-1, which deals with laboratory measurements with no or little flanking transmission. ISO 15186-3 deals with measurements under laboratory conditions, at low frequencies. This text also describes the effect of flanking transmission on measurements made using the specified method, and how intensity measurements can be used to compare the in-situ sound insulation of a building element with laboratory measurements where flanking has been suppressed (for example, ISO 140-3), to rank the partial contributions for building elements, and to measure the flanking sound reduction index for one or more transmission paths (for validation of prediction models such as those given in EN 12354-1). The method specified in this document gives values for airborne sound insulation, which are frequency dependent. These values can be converted into a single number, characterizing the acoustic performance, by application of ISO 717-1. The Committee responsible for this standard is NA 062-02-31 AA "Schalldämmung und Schallabsorption, Messung und Bewertung" ("Sound reduction and sound absorption; measurement and evaluation") at DIN.
