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 10848-4 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 126, Acoustics properties of building elements and of buildings, in collaboration with Technical
Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
ISO 10848 consists of the following parts, under the general title Acoustics — Laboratory measurement of the
flanking transmission of airborne and impact sound between adjoining rooms:
⎯ Part 1: Frame document
⎯ Part 2: Application to light elements when the junction has a small influence
⎯ Part 3: Application to light elements when the junction has a substantial influence
⎯ Part 4: Application to junctions with at least one heavy element
ISO 10848-4:2010(E)
Introduction
ISO 10848 specifies measurement methods to be performed in a laboratory test facility in order to
characterize the flanking transmission of one or several building components.
The measured quantities, normalized flanking level difference, normalized flanking impact sound pressure
level or vibration reduction index, can be used to compare different products, or to express a requirement, or
[1] [2]
as input data for prediction methods, such as ISO 15712-1 and ISO 15712-2 .

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
normalized flanking level difference

n,f
difference in the space and time average sound pressure level produced in two rooms by one or more sound
sources in one of them, when the transmission only occurs through a specified flanking path

n,f
space and time average sound pressure level in the receiving room produced by a standard tapping machine
operating at different positions on a tested floor in the source room, when the transmission only occurs
through a specified flanking path

NOTE 1 The equivalent absorption length depends on the structural reverberation time as defined in
ISO 10848-1:2006, 3.8. For light, well-damped types of elements where the actual situation has no real influence on the
sound reduction index and damping of an element, a is taken as numerically equal to the surface area S of the element,
