Acoustics - Rating of sound insulation in buildings and of building elements - Part 2: Impact sound insulation (ISO 717-2:2013)

ISO 717-2:2013: a) defines single-number quantities for impact sound insulation in buildings and of floors; b) gives rules for determining these quantities from the results of measurements carried out in one-third-octave bands in accordance with ISO 10140-3 and ISO 140-7, and in octave bands in accord-ance with that option in ISO 140-7 for field measurements only; c) defines single-number quantities for the impact sound reduction of floor coverings and floating floors calculated from the results of measurements carried out in accordance with ISO 10140-3; d) specifies a procedure for evaluating the weighted reduction in impact sound pressure level by floor coverings on lightweight floors.
The single-number quantities in accordance with ISO 717-2:2013 are intended for rating impact sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional single-number evaluation in steps of 0,1 dB is indicated for the expression of uncertainty (except for spectrum adaptation terms).The required numerical values of the single-number quantities are specified according to varying needs.
The rating of results from measurements carried out over an enlarged frequency range is described in an annex.
A method for obtaining single-number quantities for bare heavy floors according to their performance in combination with floor coverings is described in a second annex.
An example of the calculation of a single-number quantity is given in a third annex.

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 717-2 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics.
This third edition cancels and replaces the second edition (ISO 717-2:1996), which has been technically
revised. It also incorporates the Amendment ISO 717-2:1996/Amd. 1:2006.
The purpose of this revised version is to:
— allow weighting steps of 0,1 dB to be used for expression of uncertainty;
— update references.
ISO 717 consists of the following parts, under the general title Acoustics — Rating of sound insulation in
buildings and of building elements:
— Part 1: Airborne sound insulation
— Part 2: Impact sound insulation

ISO 717-2:2013(E)
Introduction
Methods of measurement of impact sound insulation in buildings and of building elements have been
standardized in ISO 10140-3 and ISO 140-7. These methods give values for the impact sound insulation
which are frequency dependent. The purpose of this part of ISO 717 is to standardize a method whereby
the frequency-dependent values of impact sound insulation can be converted into a single number
characterizing the acoustical performance.
The method has been widely used since 1968. However, since there is some evidence that it could be improved,
a spectrum adaptation term is added and it is recommended that experience be gathered with this.
References to standards which provide data for single-number evaluation are meant to be examples and
not complete surveys.
