Acoustics - Field measurements of airborne and impact sound insulation and of service equipment sound - Survey method (ISO 10052:2021)

This document specifies field survey methods for measuring
a) airborne sound insulation between rooms,
b) impact sound insulation of floors,
c) airborne sound insulation of façades, and
d) sound pressure levels in rooms caused by service equipment.
The methods described in this document are applicable for measurements in rooms of dwellings or in rooms of comparable size with a maximum of 150 m3.
For airborne sound insulation, impact sound insulation and façade sound insulation the method gives values which are (octave band) frequency dependent. They can be converted into a single number characterising the acoustical performances by application of ISO 717-1 and ISO 717-2. For heavy/soft impact sound insulation, the results also are given as A-weighted maximum impact sound pressure level. For service equipment sound the results are given directly in A - or C -weighted sound pressure levels.

Akustik - Messung der Luftschalldämmung und Trittschalldämmung und des Schalls von haustechnischen Anlagen in Gebäuden - Kurzverfahren (ISO 10052:2021)

Dieses Dokument legt Kurzverfahren für die Messung von
a) Luftschalldämmung zwischen Räumen,
b) Trittschalldämmung von Decken,
c) Luftschalldämmung von Fassaden und
d) durch haustechnische Anlagen in Räumen erzeugten Schalldruckpegeln
in Gebäuden fest.
Die in diesem Dokument beschriebenen Verfahren gelten für Messungen in Räumen von Wohnhäusern oder in Räumen vergleichbarer Größe bis höchstens 150 m3.
Bei der Luftschalldämmung, der Trittschalldämmung und der Fassadenschalldämmung ergibt das Verfahren (oktavband )frequenzabhängige Werte. Sie können durch Anwendung von ISO 717 1 und ISO 717 2 in Einzahlangaben umgewandelt werden, die die akustischen Eigenschaften kennzeichnen. Für schwere/weiche Trittschalldämmung werden die Ergebnisse auch als maximaler A bewerteter Trittschallpegel angegeben. Für den Schall von haustechnischen Anlagen werden die Ergebnisse direkt als A  oder C bewertete Schalldruckpegel angegeben.

Acoustique - Mesurages in situ de l'isolement aux bruits aériens et de la transmission des bruits de choc ainsi que du bruit des équipements - Méthode de contrôle (ISO 10052:2021)

Le présent document spécifie des méthodes de contrôle in situ pour le mesurage:
a) de l’isolement aux bruits aériens entre les pièces;
b) de la transmission des bruits de choc par les planchers;
c) de la transmission des bruits aériens par les façades; et
d) des niveaux de pression acoustique émis par les équipements techniques dans les pièces.
Les méthodes décrites dans le présent document sont applicables aux mesurages effectués dans les pièces de bâtiments d’habitation ou dans des locaux de dimensions comparables de 150 m3, au maximum.
Pour l’isolement aux bruits aériens, la transmission des bruits de choc et la transmission des bruits par les façades, la méthode donne des valeurs en fonction de la fréquence (bande d’octave). En appliquant l’ISO 717-1 et l’ISO 717-2, elles peuvent être converties en une valeur unique caractérisant les performances acoustiques. Pour la transmission des bruits de choc lourd/souple, les résultats sont également donnés en niveau de pression acoustique du bruit de choc maximal pondéré A. Pour le bruit des équipements techniques, les résultats sont donnés directement en niveaux de pression acoustique pondérés A ou C.

Introduction
This document describes survey field test methods which can be used for surveying the acoustic
characteristics of the airborne sound insulation, impact sound insulation and of the sound pressure
levels from service equipment. The methods may be used for screening tests of the acoustical properties
of buildings. The methods are not intended to be applied for measuring acoustical properties of building
elements.
The approach of the survey methods is to simplify the measurement of sound pressure levels in rooms
by using a hand-held sound level instrument and by manually sweeping the microphone in the room
space. The correction for reverberation time can be either estimated by usage of tabular values or be
based on measurements. The measurement of airborne and impact sound insulation is carried out in
octave bands. For measuring sound from domestic service equipment, A - or C -weighted sound pressure
levels are recorded.
Measurements are performed with specified operation conditions and operation cycles. The operating
conditions and operating cycles given in Annex B are only used if they are not opposed to national
requirements and regulations.
The measurement uncertainty of the results obtained using the survey method is a priori larger than
the uncertainty inherent in the corresponding test methods on engineering level.
NOTE Engineering methods for field measurements of airborne and impact sound insulation are dealt with
in ISO 16283-1 and ISO 16283-2. Engineering methods for field measurements of airborne sound insulation of
façade elements and façades are dealt with in ISO 16283-3. An engineering method for measurement of service
equipment sound is dealt with in ISO 16032.

Introduction
This document describes survey test methods which can be used for surveying the acoustic
characteristics of the airborne sound insulation, impact sound insulation and of the sound pressure
levels from service equipment. The methods may be used for screening tests of the acoustical properties
of buildings. The methods are not intended to be applied for measuring acoustical properties of building
elements.
The approach of the survey methods is to simplify the measurement of sound pressure levels in rooms
by using a hand-held sound level instrument and by manually sweeping the microphone in the room
space. The correction for reverberation time can be either estimated by usage of tabular values or be
based on measurements. The measurement of airborne and impact sound insulation is carried out in
octave bands. For measuring sound from domestic service equipment, A - or C -weighted sound pressure
levels are recorded.
Measurements are performed with specified operation conditions and operation cycles. The operating
conditions and operating cycles given in Annex B are only used if they are not opposed to national
requirements and regulations.
The measurement uncertainty of the results obtained using the survey method is a priori larger than
the uncertainty inherent in the corresponding test methods on engineering level.
NOTE Engineering methods for field measurements of airborne and impact sound insulation are dealt with
in ISO 16283-1 and ISO 16283-2. Engineering methods for field measurements of airborne sound insulation of
façade elements and façades are dealt with in ISO 16283-3. An engineering method for measurement of service
equipment sound is dealt with in ISO 16032.

Acoustics — Field measurements of airborne and impact
sound insulation and of service equipment sound —
Survey method
1 Scope
This document specifies field survey methods for measuring:
a) airborne sound insulation between rooms;
b) impact sound insulation of floors;
c) airborne sound insulation of façades; and
d) sound pressure levels in rooms caused by service equipment.
The methods described in this document are applicable for measurements in rooms of dwellings or in
3
rooms of comparable size with a maximum of 150 m .
For airborne sound insulation, impact sound insulation and façade sound insulation the method gives
values which are (octave band) frequency dependent. They can be converted into a single number
characterising the acoustical performances by application of ISO 717-1 and ISO 717-2. For heavy/soft
impact sound insulation, the results also are given in overall A-weighted maximum impact sound
pressure level. For service equipment sound the results are given directly in A - or C -weighted sound
pressure levels.
