Acoustics - Measurement of sound insulation in buildings and of building elements using sound intensity - Part 2: Field measurements (ISO 15186-2:2003)

ISO 15186-2:2003 specifies a sound intensity method to determine the in-situ sound insulation of walls, floors, doors, windows and small building elements. It 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.
ISO 15186-2:2003 can be used by laboratories that could 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.
ISO 15186-2:2003 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 (i.e. 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).
This method gives values for airborne sound insulation, which are frequency dependent. They can be converted into a single number, characterizing the acoustic performance, by application of ISO 717-1.
The reproducibility of this intensity method is estimated to be equal to or better than that of the methods of ISO 140-10 and ISO 140-4, when measuring a single small and large building element, respectively.

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

1 Anwendungsbereich
1.1 Allgemeines
Der vorliegende Teil von ISO 15186 legt ein Schallintensitätsverfahren zur Bestimmung der Schalldämmung
von Wänden, Fußböden, Fenstern und kleinen Bauteilen durch Messungen am Bau fest. Das Verfahren ist für
Messungen vorgesehen, die bei vorhandener Flankenübertragungen erfolgen müssen. Es kann eingesetzt
werden, um Schallleistungsdaten zur Diagnose von Flankenübertragungen zu ermitteln oder um Parameter
der Flankenschalldämmung zu messen.
Dieser Teil von ISO 15186 kann in Prüfständen angewendet werden, die die Anforderungen von ISO 15186-1,
in welcher Prüfstandmessungen ohne oder mit nur sehr geringer Flankenübertragung behandelt sind, nicht
erfüllen. ISO 15186-3 behandelt Messungen unter Prüfstandbedingungen bei tiefen Frequenzen.
Der vorliegende Teil von ISO 15186 beschreibt außerdem die Wirkung von Flankenübertragungen auf mit
dem festgelegten Verfahren durchgeführte Messungen und die Art und Weise, in der die Intensitätsmessungen
genutzt werden können, um
- die vor Ort vorliegende Schalldämmung eines Bauteils mit Prüfstands-Messungen mit unterdrückter
Flankenübertragung (z. B. ISO 140-3) zu vergleichen,
- Bauteile in Hinblick auf den Anteil an der Schalltransmission zu reihen,
- das Flanken-Schalldämm-Maß für einen oder mehrere Übertragungswege zu messen (zur Validierung
der z. B. in EN 12354-1 angegebenen Vorhersagemodelle).
Dieses Verfahren gibt frequenzabhängige Werte für die Luftschalldämmung an. Diese Werte können unter
Anwendung von ISO 717-1 in Einzahlangaben umgerechnet werden, die die akustischen Eigenschaften
charakterisieren.
1.2 Präzision
Die Vergleichpräzision dieses Intensitätsverfahrens ist bei Messung an einem einzelnen kleinen oder großen
Bauteil schätzungsweise gleich oder besser als die der Verfahren aus ISO 140-10 und ISO 140-4.

Acoustique - Mesurage par intensité de l'isolation acoustique des immeubles et des éléments de construction - Partie 2: Mesurages in situ (ISO 15186-2:2003)

L'ISO 15186-2:2003 spécifie une méthode d'intensité acoustique pour déterminer l'isolement acoustique in situ des murs, des sols, des portes, des fenêtres et des petits éléments de construction. Elle est destinée aux mesurages devant être réalisés en présence de transmissions latérales. Elle peut être utilisée pour fournir des données relatives à la puissance acoustique en vue d'une analyse des transmissions latérales ou pour mesurer les paramètres d'isolement acoustique latéral.
L'ISO 15186-2:2003 peut être utilisée par les laboratoires n'ayant pu répondre aux exigences de l'ISO 15186‑1, qui traite des mesurages en laboratoire sans ou quasi-sans transmission latérale. L'ISO 15186‑3 couvre les mesurages effectués dans des conditions de laboratoire, aux basses fréquences.
L'ISO 15186-2:2003 décrit également l'effet des transmissions latérales sur les mesurages réalisés à l'aide de la méthode spécifiée, et explique comment utiliser les mesurages d'intensité pour établir une comparaison entre l'isolement acoustique in situ d'un élément de construction et les mesurages de laboratoire pour lesquels les transmissions latérales ont été supprimées (ISO 140‑3); pour établir un classement des contributions partielles des éléments de construction; et pour mesurer l'indice d'affaiblissement acoustique latéral pour un ou plusieurs chemins de transmission (en vue de valider des modèles de prévision, tels que ceux donnés dans l'EN 12354‑1).
Cette méthode donne des valeurs d'isolement aux bruits aériens, qui sont dépendantes des fréquences. Elles peuvent être converties en un indice unique qui caractérise la performance acoustique, par application de l'ISO 717‑1.

Akustika - Merjenje zvočne izolirnosti v stavbah in zvočne izolirnosti gradbenih elementov z uporabo zvočne intenzitete - 2. del: Terenska merjenja (ISO 15186-2:2003)

Ta del ISO 15186 določa metodo zvočne intenzitete za določevanje in situ zvočne izolirnosti sten, tal, vrat, oken in majhnih gradbenih elementov. Namenjen je za merjenja, ki morajo biti izvedena v prisotnosti bočnega prenosa. Lahko se uporablja za zagotavljanje podatkov o moči zvoka za diagnostično analizo bočnega prenosa ali za merjenje parametrov izolirnosti pred bočnim prenosom zvoka. Ta del ISO 15186 lahko uporabljajo laboratoriji, ki niso mogli izpolniti pogojev ISO 15186-1, kateri obravnava laboratorijska merjenja brez ali z majhnim bočnim prenosom. ISO 15186-3 obravnava merjenja pod laboratorijskimi pogoji, pri nizkih frekvencah.

ISO 15186-2:2003(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 15186-2 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
ISO 15186 consists of the following parts, under the general title Acoustics — Measurement of sound
insulation in buildings and of building elements using sound intensity:
 Part 1: Laboratory measurements
 Part 2: Field measurements
 Part 3: Laboratory measurements at low frequencies

INTERNATIONAL STANDARD ISO 15186-2:2003(E)

Acoustics — Measurement of sound insulation in buildings and
of building elements using sound intensity —
Part 2:
Field measurements
1 Scope
1.1 General
This part of ISO 15186 specifies a sound intensity method to determine the in-situ sound insulation of walls,
floors, doors, windows and small building elements. It 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.
This part of ISO 15186 can be used by laboratories that could 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 part of ISO 15186 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 (i.e. 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).
This method gives values for airborne sound insulation, which are frequency dependent. They can be
converted into a single number, characterizing the acoustic performance, by application of ISO 717-1.
1.2 Precision
The reproducibility of this intensity method is estimated to be equal to or better than that of the methods of
ISO 140-10 and ISO 140-4, when measuring a single small and large building element, respectively.
NOTE 1 If sound reduction measures made using this method are to be compared with those made using the
conventional reverberation room method in various parts of ISO 140, then it will be necessary to introduce an adaptation
term that reflects the bias between the test methods. This term is given in Annex A.
NOTE 2 Some information about the accuracy for this part of ISO 15186 and its relationship to the sound reduction
index measured according to ISO 140-3 and ISO 140-4 is given in Annex B.
NOTE 3 Flanking transmission is discussed in Annex C.
