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 717-1 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
This second edition cancels and replaces the first edition (ISO 717-1:1996+Amd 1:2004), which has been
technically revised.
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

Introduction
Methods of measurement of airborne sound insulation of building elements and in buildings have been
standardized e.g. in ISO 10140-2, ISO 140-4, and ISO 140-5. The purpose of this part of ISO 717 is to
standardize a method whereby the frequency-dependent values of airborne sound insulation can be converted
into a single number characterizing the acoustical performance.
The purpose of this revised version is to
• to allow weighting steps of 0.1 dB to be used for expression of uncertainty,
• to include the existing Amendment 1 of ISO 717, and
• to update references.

References to standards which provide data for single-number evaluation are meant to be examples and therefore are not
complete.

DRAFT INTERNATIONAL STANDARD ISO/DIS 717-1

Acoustics — Rating of sound insulation in buildings and of
building elements — Part 1: Airborne sound insulation
1 Scope
This part of ISO 717
a) defines single-number quantities for airborne sound insulation in buildings and of building elements such
as walls, floors, doors and windows;
b) takes into consideration the different sound level spectra of various noise sources such as noise sources
inside a building and traffic outside a building; and
c) gives rules for determining these quantities from the results of measurements carried out in one-third-
octave or octave bands in accordance with ISO 10140-2, ISO 140-4 and ISO 140-5.
The single-number quantities in accordance with this part of ISO 717 are intended for rating the airborne
sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional
single-number evaluation in 1/10-dB-steps 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 single-number quantities are based on results of measurements in one-third-octave bands
or octave bands.
For laboratory measurements made in accordance with ISO 10140, single-number quantities should be
calculated using one-third-octave bands only.
The rating of results of measurements carried out over an enlarged frequency range is dealt with in Annex B.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

single-number quantity for airborne sound insulation rating
value, in decibels, of the reference curve at 500 Hz after shifting it in accordance with the method specified in
this part of ISO 717
NOTE 1 Terms and symbols for the single-number quantity used depend on the type of measurement. Examples are
listed in Table 1 for airborne sound insulation properties of building elements and in Table 2 for airborne sound insulation
in buildings. In general, new single-number quantities are derived in a similar way.
3.2
spectrum adaptation term
value, in decibels, to be added to the single-number rating (e.g. R ) to take account of the characteristics of
w
particular sound spectra
NOTE 1 Two sound spectra are defined (in one-third-octave bands and in octave bands) in this part of ISO 717.
NOTE 2 Annex A gives information on the purpose of introducing these two spectrum adaptation terms.

4 Procedure for evaluating single-number quantities
4.1 General
The values obtained in accordance with ISO 10140-2, ISO 140-4 and ISO 140-5 are compared with reference
values (see 4.2) at the frequencies of measurement within the range 100 Hz to 3 150 Hz for one-third-octave
bands and 125 Hz to 2 000 Hz for octave bands.
The comparison shall be carried out as specified in 4.4
Furthermore, two spectrum adaptation terms shall be calculated (see 4.5) based on two typical spectra within
the frequency range as quoted above. These two terms may optionally be supplemented by additional
spectrum adaptation terms covering (if need be and if measured data are available) a wider frequency range
between 50 Hz and 5 000 Hz.
4.2 Reference values
The set of reference values used for comparison with measurement results shall be as given in table 3. The
reference curves are shown in Figure 1 and Figure 2.
4.3 Sound spectra
The set of sound spectra in one-third-octave bands and octave bands to calculate the spectrum adaptation
terms shall be as given in Table 4 and shown in Figure 3 and Figure 4. The spectra are A-weighted and the
overall spectrum level is normalized to 0 dB.
