Acoustics - Measurement of sound insulation in buildings and of building elements using sound intensity - Part 3: Laboratory measurements at low frequencies (ISO 15186-3:2002)
ISO 15186-3:2002 specifies a sound intensity method to determine the sound reduction index and the element-normalized level difference of building elements at low frequencies. This method has significantly better reproducibility in a typical test facility than those of ISO 140-3, ISO 140-10 and ISO 15186-1. The results are more independent of the room dimensions of the laboratory and closer to values that would be measured between rooms of volume greater than 300 m3. ISO 15186-3 is applicable in the frequency range 50 Hz to 160 Hz but is mainly intended for the frequency range 50 Hz to 80 Hz.
NOTE For elements faced with thick, porous absorbers, the recommended frequency range is 50 Hz to 80 Hz.
The main differences between the methods of ISO 15186-1 and ISO 15186-3 are that in ISO 15186-3
the sound pressure level of the source room is measured close to the surface of the test specimen, andthe surface opposite the test specimen in the receiving room is highly absorbing and converts the room acoustically into a duct with several propagating cross-modes above the lowest cut-on frequency.
The results found by the method of ISO 15186-3 can be combined with those of ISO 140-3 and ISO 15186-1 to produce data in the frequency range 50 Hz to 5 000 Hz.
The reproducibility of this intensity method is, for all frequencies, estimated to be equal to or better than that found with the method of ISO 140-3 at 100 Hz.
Some comparisons of data obtained with this part of ISO 15186 and with ISO 140-3 are given for information.
Akustik - Bestimmung der Schalldämmung in Gebäuden und von Bauteilen aus Schallintensitätsmessungen - Teil 3: Messungen bei niedrigen Frequenzen im Prüfstand (ISO 15186-3:2002)
1 Anwendungsbereich
1.1 Allgemeines
Der vorliegende Teil von ISO 15186 legt ein Schallintensitätsverfahren zur Bestimmung des Schalldämm-
Maßes und der Norm-Schallpegeldifferenz von Bauteilen bei tiefen Frequenzen fest. Dieses Verfahren besitzt
in einer typischen Prüfeinrichtung eine wesentlich bessere Vergleichpräzision als die Verfahren nach
ISO 140-3, ISO 140-10 und ISO 15186-1. Die Ergebnisse sind von den Raummaßen des Laboratoriums
unabhängiger und liegen näher an Werten, die zwischen Räumen mit einem Volumen von mehr als 300 m3
messbar wären. Dieser Teil von ISO 15186 ist anwendbar im Frequenzbereich von 50 Hz bis 160 Hz, ist
jedoch vor allem für den Frequenzbereich von 50 Hz bis 80 Hz vorgesehen.
ANMERKUNG Für Bauteile, die mit dicken, porösen Schallabsorbern verkleidet sind, ist der empfohlene
Frequenzbereich 50 Hz bis 80 Hz.
Der Hauptunterschied zwischen den Verfahren von ISO 15186-1 und ISO 15186-3 besteht darin, dass in
ISO 15186-3
a) der Schalldruckpegel des Senderaums nahe der Oberfläche des Prüfgegenstands gemessen wird und
b) die Oberfläche gegenüber dem Prüfgegenstand im Empfangsraum stark absorbierend ist und den Raum
akustisch in einen Kanal mit mehreren sich ausbreitenden Quermoden oberhalb der tiefsten unteren
Grenzfrequenz umwandelt.
Um Daten für den Frequenzbereich von 50 Hz bis 5 000 Hz zu erhalten, können die mit dem Verfahren nach
ISO 15186-3 ermittelten Ergebnisse mit den Ergebnissen aus ISO 140-3 und ISO 15186-1 kombiniert werden.
1.2 Präzision
Die Vergleichpräzision dieses Intensitätsverfahrens ist für alle Frequenzen schätzungsweise gleich oder
besser als die Vergleichpräzision der Verfahren aus ISO 140-3 bei 100 Hz.
In Anhang B sind zu Informationszwecken einige Vergleiche der mit dem Verfahren nach diesem Teil von
ISO 15186 und der mit dem Verfahren nach ISO 140-3 ermittelten Daten angegeben.
Acoustique - Mesurage par intensité de l'isolation acoustique des immeubles et des éléments de construction - Partie 3: Mesurages en laboratoire à de basses fréquences (ISO 15186-3:2002)
L'ISO 15186-3:2002 spécifie une méthode d'intensité acoustique pour déterminer l'indice d'affaiblissement acoustique et l'isolement acoustique normalisé des éléments de construction aux basses fréquences. La reproductibilité de cette méthode est nettement meilleure dans un laboratoire type que dans les conditions de l'ISO 140-3:1995, l'ISO 140-10:1991 et l'ISO 15186-1:2000. Les résultats dépendent moins des dimensions des salles d'essai du laboratoire, et sont plus proches des valeurs qui seraient mesurées entre des salles d'un volume supérieur à 300 m3. L'ISO 15186-3:2002 est applicable à la gamme de fréquences comprise entre 50 Hz et 160 Hz, mais elle est principalement destinée à la gamme de fréquences comprise entre 50 Hz et 80 Hz.
Les principales différences entre les méthodes de l'ISO 15186-1:2000 et celles de l'ISO 15186-3:2002 sont les suivantes: dans l'ISO 15186-3:2002, le niveau de pression acoustique de la salle d'émission est mesuré à proximité de la surface de l'éprouvette, et la surface opposée à l'éprouvette dans la salle de réception est hautement absorbante et transforme acoustiquement la salle en un conduit ayant plusieurs modes obliques de propagation au-dessus de la fréquence de coupure la plus basse.
Les résultats obtenus par le biais de la méthode de l'ISO 15186-3:2002 peuvent être combinés à ceux de l'ISO 140‑3:1995 et de l'ISO 15186-1:2000 afin de produire des données dans la gamme de fréquences comprise entre 50 Hz et 5 000 Hz.
Akustika - Merjenje zvočne izolirnosti v stavbah in zvočne izolirnosti gradbenih elementov z uporabo zvočne intenzitete - 3. del: Laboratorijska merjenja pri nizkih frekvencah (ISO 15186-3:2002)
Ta del ISO 15186 določa metodo zvočne intenzitete za določevanje pokazatelja zvočnega zmanjševanja in elementarno normalizirano raven razlike gradbenih elementov pri nizkih frekvencah. Ta metoda ima znatno boljšo obnovljivost v tipičnem preskusnem objektu kot metoda iz ISO 140-3, ISO 140-10 in ISO 15186-1. Rezultati so manj odvisni od mer prostorov laboratorija in bližje vrednostim, ki bi bile izmerjene med prostori z volumnom večjim od 300 m3. Ta del ISO 15186 velja v frekvenčnem razponu od 50 Hz do 160 Hz, vendar je predvsem namenjen za frekvenčni razpon od 50 Hz do 80 Hz. Za elemente, soočene z debelimi, poroznimi absorberji je priporočen frekvenčni razpon od 50 Hz do 80 Hz.

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 3.
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 part of ISO 15186 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15186-3 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: In-situ conditions
