Part 4: Equipment for extended high-frequency audiometry
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in the
subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2)
The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3)
They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
4)
In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
This part of International Standard IEC 645 has been prepared by IEC technical committee 29:
Electroacoustics.
It forms the first edition of IEC 645-4.
The text of this standard is based on the following documents:
DIS Report on voting
29(CO)215
29(CO)220
Full information on the voting for the approval of this standard can be found in the report
on voting indicated in the above table.

INTRODUCTION
This International Standard describes equipment which is designed for the measurement
of hearing in the frequerrcy range from 8 000 Hz to 16 000 Hz. Part 1 of IEC 645 specifies
the requirements for pure tone audiometers with frequencies within the conventional range
for audiometry from 125 Hz to 8 000 Hz. Many of the requirements are common for both
frequency ranges and therefore this standard includes only such requirements that are
specific to the high-frequency range.

Part 4: Equipment for extended high-frequency audiometry
1 Scope
This International Standard specifies requirements for audiometric equipment designed
for use in pure tone audiometry in the frequency range from 8 000 Hz to 16 000 Hz, in
addition to those that are applicable and specified in IEC 645-1.
The purpose of the standard is to ensure that extended high-frequency audiometry
performed on a given human ear with different types of equipment which comply with this
standard shall give substantially similar results.
2 Normative references
