HEARING AIDS –
Part 14: Specification of a digital interface device
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 co-operation 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 express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are 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.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60118-14 has been prepared by IEC technical committee 29:
Electroacoustics.
The text of this standard is based on the following documents:
FDIS Report on voting
29/389/FDIS 29/400/RVD
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 part of IEC 60118 has been prepared to define the electrical and mechanical
characteristics of the interface (the signals and connectors) to be used for the electrical setting
of hearing aid parameters.
This standard was motivated by a desire to avoid the problem of incompatibility between
the hearing aids and the parameter setting devices produced by different manufacturers.
The standard assumes a general configuration for the electrical setting of parameters which
consist of
– a general-purpose control device, such as a desktop computer;
– a hearing aid with electrical control of parameter values;
– an interface to connect the computer to the hearing aid.
This standard only specifies the requirements for the interface between the control device and
the hearing aid.

HEARING AIDS –
Part 14: Specification of a digital interface device
1 Scope
This part of IEC 60118 specifies the electrical and mechanical requirements for an interface
device to allow a general-purpose control device such as a desktop computer to be connected
to hearing aids, for the purpose of electrical setting of their operating parameters.
There is no specification of anything within the hearing aid, such as types of parameters and
their signal processing characteristics, nor is there any specification of the parameter setting
procedure – the method used to determine which settings are most appropriate to the person
wearing the hearing aid. This standard is restricted to the digital interface between the control
device and the hearing aid.
This standard provides a specification such that all hearing aids which can be programmed by
the specified digital interface may have their parameters set by a single control device and
interface device.
The specifications of this standard are for use in connection with hearing aids with parameters
set by a direct electrical connection using a cable. They do not cover hearing aids with
parameters controlled by radio frequency or infrared transmission, or any other "wireless"
method of control.
