OCCLUDED-EAR SIMULATOR FOR THE MEASUREMENT
OF EARPHONES COUPLED TO THE EAR BY EAR INSERTS
FOREWORD
1) The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
rnational
National Committees having a special interest therein are represented, express, as nearly as possible, an inte
consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
rnational unification, the IEC expresses the wish that all National Committees should adopt the
3) In order to promote inte
text of the I EC recommendation for their national rules in so far as national conditions will permit. Any divergence
between the I EC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in
the latter.
PREFACE
This standard has been prepared by Sub-Committee 29C: Measuring Devices, of IEC Technical
Committee No. 29: Electro-acoustics.
A first draft was discussed at the meeting held in Stockholm in 1979. As a result of this meeting, a
draft, Document 29C(Central Office)42, was submitted to the National Committees for approval
under the Six Months' Rule in October 1979.
The National Committees of the following countries voted explicitly in favour of publication:
Australia Netherlands
Belgium Norway
South Africa (Republic of)
China
Czechoslovakia Spain
Denmark Sweden
France Turkey
Germany Union of Soviet
Italy Socialist Republics

This standard specifies an occluded-ear simulator intended for the calibration of inse
phones in the frequency range 100 Hz to 10 000 Hz in terms of the sound pressure at the ear-
drum.
The occluded-ear simulator is also designed as the basis for a later extensio
