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 3382-1 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
This first edition of ISO 3382-1, together with ISO 3382-2 and ISO 3382-3, cancels and replaces
ISO 3382:1997, of which it constitutes a technical revision. Annex A has been extended with information on
JND (just noticeable difference), recommended frequency averaging and by the addition of a new parameter
for LEV (listener envelopment). A new Annex C has been added with parameters for the acoustic conditions
on the orchestra platform.
ISO 3382 consists of the following parts, under the general title Acoustics — Measurement of room acoustic
parameters:
⎯ Part 1: Performance spaces
⎯ Part 2: Reverberation time in ordinary rooms
Open plan spaces are to form the subject of a future part 3.

ISO 3382-1:2009(E)
Introduction
The reverberation time of a room was once regarded as the predominant indicator of its acoustical properties.
While reverberation time continues to be regarded as a significant parameter, there is reasonable agreement
that other types of measurements, such as relative sound pressure levels, early/late energy ratios, lateral
energy fractions, interaural cross-correlation functions and background noise levels, are needed for a more
complete evaluation of the acoustical quality of rooms.
This part of ISO 3382 establishes a method for obtaining reverberation times from impulse responses and
from interrupted noise. The annexes introduce the concepts and details of measurement procedures for some
of the newer measures, but these do not constitute a part of the formal specifications of this part of ISO 3382.
The intention is to make it possible to compare reverberation time measurements with higher certainty and to
promote the use of and consensus in measurement of the newer measures.
Annex A presents measures based on squared impulse responses: a further measure of reverberation (early
decay time) and measures of relative sound levels, early/late energy fractions and lateral energy fractions in
auditoria. Within these categories, there is still work to be done in determining which measures are the most
suitable to standardize upon; however, since they are all derivable from impulse responses, it is appropriate to
introduce the impulse response as the basis for standard measurements. Annex B introduces binaural
measurements and the head and torso simulators (dummy heads) required to make binaural measurements
in auditoria. Annex C introduces the support measures that have been found useful for evaluating the acoustic
conditions from the musicians’ point of view.

1 Scope
This part of ISO 3382 specifies methods for the measurement of reverberation time and other room acoustical
parameters in performance spaces. It describes the measurement procedure, the apparatus needed, the
coverage required, and the method of evaluating the data and presenting the test report. It is intended for the
application of modern digital measuring techniques and for the evaluation of room acoustical parameters
derived from impulse responses.

3 Terms and definitions
For the purposes of this part of ISO 3382, the following terms and definitions apply.

decay curve
graphical representation of the decay of the sound pressure level in a room as a function of time after the
sound source has stopped
[ISO 354:2003, 3.1]
NOTE 1 It is possible to measure this decay either after the actual cut-off of a continuous sound source in the room or
derived from the reverse-time integrated squared impulse response of the room (see Clause 5).
NOTE 2 The decay directly obtained after non-continuous excitation of a room (e.g. by recording a gunshot with a level
recorder) is
