Methods for measuring the sound insulation of building elements and the acoustic performances of buildings
To draft standards on methods for: - the laboratory or field measurements of the sound insulation of building elements and of the field measurement of the acoustic performances of buildings; - the measurement of sound absorption.
General Information
This document specifies procedures to measure in laboratory the impact sound level reduction of isolated heavy landings connected to a heavy wall, isolated heavy flights of stairs connected to a heavy landing, lower or upper floor, and lightweight stairs connected to a heavy wall, lower or upper floor.
This document also considers the characterization of isolating elements for heavy landings or heavy flights of stairs in terms of an insertion loss expressed as an impact sound level difference. The corresponding procedure is given in a normative annex (Annex A), separated from the other procedures for the sake of clarity.
The tests are performed in defined test configurations and the test results are firstly restricted to the test configurations as described in the test report. The data can be used for comparing the performance of products and as input for EN ISO 12354-2:2017, Annex F, to calculate the sound pressure levels produced by the same stairs and isolating elements when installed in buildings.
The test procedures defined in this document comprise the frequency range from 50 Hz to 5000 Hz.

This test method covers the use of an impedance tube, two microphone locations and a frequency
analysis system for the determination of the sound absorption coefficient of sound absorbing materials
for normal incidence sound incidence. It can also be applied for the determination of the acoustical
surface impedance or surface admittance of sound absorbing materials. As an extension, it can also be
used to assess intrinsic properties of homogeneous acoustical materials such as their characteristic
impedance, characteristic wavenumber, dynamic mass density and dynamic bulk modulus.
The test method is similar to the test method specified in ISO 10534-1[1] in that it uses an impedance
tube with a sound source connected to one end and the test sample mounted in the tube at the other
end. However, the measurement technique is different. In this test method, plane waves are generated
in a tube by a sound source, and the decomposition of the interference field is achieved by the
measurement of acoustic pressures at two fixed locations using wall-mounted microphones or an intube
traversing microphone, and subsequent calculation of the complex acoustic transfer function and
quantities reported in the previous paragraph. The test method is intended to provide an alternative,
and generally much faster, measurement technique than that of ISO 10534-1[1].
Normal incidence absorption coefficients coming from impedance tube measurements are not
comparable with random incidence absorption coefficients measured in reverberation rooms according
to ISO 354[2]. The reverberation room method will (under ideal conditions) determine the sound
absorption coefficient for diffuse sound incidence. However, the reverberation room method requires
test specimens which are rather large. The impedance tube method is limited to studies at normal and
plane incidence and requires samples of the test object which are of the same size as the cross-section
of the impedance tube. For materials that are locally reacting only, diffuse incidence sound absorption
coefficients can be estimated from measurement results obtained by the impedance tube method (see
Annex E).
Through the whole document, a e+ jt time convention is used.

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.

ISO 16032:2004 specifies methods for measuring the sound-pressure level produced by service equipment attached to or installed in buildings. It specifically covers measurements on sanitary installations, mechanical ventilation, heating and cooling service equipment, lifts, rubbish chutes, boilers, blowers, pumps and other auxiliary service equipment, and motor-driven car park doors, but can also be applied to other equipment attached to or installed in buildings.
The methods are suitable for rooms with volumes of approximately 300 cubic metres or less in e.g. dwellings, hotels, schools, offices and hospitals. The standard is not in general intended for measurements in large auditoria such as concert halls. However, the operating conditions and operating cycles in Annex B can be used in such cases.
The service equipment sound-pressure level is determined as the maximum A-weighted and optionally C-weighted sound-pressure level occurring during a specified operation cycle of the service equipment under test, or as the equivalent continuous sound-pressure level determined with a specified integration time. A-weighted and C-weighted values are calculated from octave-band measurements.

This test method covers the use of an impedance tube, two microphone locations and a digital frequency analysis system for the determination of the sound absorption coefficient of sound absorbers for normal sound incidence. It can also be applied for the determination of the acoustical surface impedance or surface admittance of sound absorbing materials. Since the impedance ratios of a sound absorptive material are related to its physical properties, such as airflow resistance, porosity, elasticity and density, measurements described in this test method are useful in basic research and product development.
The test method is similar to the test method specified in ISO 10534-1 in that it uses an impedance tube with a sound source connected to one end and the test sample mounted in the tube at the other end. However, the measurement technique is different. In this test method, plane waves are generated in a tube by a noise source, and the decomposition of the interference field is achieved by the measurement of acoustic pressures at two fixed locations using wall-mounted microphones or an in-tube traversing microphone, and subsequent calculation of the complex acoustic transfer function, the normal incidence absorption and the impedance ratios of the acoustic material. The test method is intended to provide an alternative, and generally much faster, measurement technique than that of ISO 10534-1.
Compared with the measurement of the sound absorption in a reverberation room according to the method specified in ISO 354, there are some characteristic differences. The reverberation room method will (under ideal conditions) determine the sound absorption coefficient for diffuse sound incidence, and the method can be used for testing of materials with pronounced structures in the lateral and normal directions. However, the reverberation room method requires test specimens which are rather large, so it is not convenient for research and development work, where only small samples of the absorber are available. The impedance tube method is limited to parametric studies at normal incidence but requires samples of the test object which are of the same size as the cross-section of the impedance tube. For materials that are locally reacting, diffuse incidence sound absorption coefficients can be estimated from measurement results obtained by the impedance tube method. For transformation of the test results from the impedance tube method (normal incidence) to diffuse sound incidence, see annex F.
