4.1 General
The entire system’s audio processing shall be digital. Overall latency between the analogue input
(microphone) to the analogue output (headphone) shall not exceed 10 ms.
All sound pressure levels (SPL) referred to in this document are based both on a nominal input level
between 85 dB and 115 dB at 30 cm speaking distance, and on the use of passive headphones
SPL SPL
with an impedance of 32 ohms and a throughput between 95 dB and 115 dB per milliwatt.
SPL SPL
4.2 Frequency response
The overall interpreting system excluding the microphones and headphones shall correctly reproduce
audio-frequencies between at least 125 Hz and 15 000 Hz ± 3 dB, high-pass with attenuation of at least
12 dB per octave for frequencies below 125 Hz in order to improve speech intelligibility.
The microphone and the headphones shall correctly reproduce audio-frequencies between 125 Hz and
15 000 Hz ± 10 dB.

4.3 Amplitude nonlinearity
The system shall be free of perceptible distortion; total harmonic distortion (THD) should be less
than 1 %.
4.4 Noise and hum
The system shall be free of perceptible noise and hum, with an end-to-end signal-to-noise ratio of at
least 95 dBA at maximum input level.
4.5 Hearing protection
An audible hearing-damage warning shall be activated when the average sound pressure level is higher
than 80 dBA for more than 1 min.
SPL
The system shall limit loud sounds, with a maximum output level of 94 dBA for any duration longer
SPL
than 100 ms.
4.6 Level consistency across channels
The volume of each channel should be automatically adjusted to minimize the volume difference
between channels, as well as between channels and the floor assuming that the input level varies
between nominal and ±12 dB.
5 Interpreter console
5.1 General
There shall be one console for each interpreter, containing individual controls for listening and
speaking, including the relevant indicators.
The console may be either freestanding on or integrated into the working surface. The surface of the
console shall be matte and non-reflecting.
It shall be possible to quickly and easily service or replace a malfunctioning console or its microphone
without impairing the functioning of the rest of the system.
The console shall be fully and equitably usable by non-sighted persons, as well as persons with low
vision, anomalous colour vision, or age-related degeneration of vision. It shall be easy to operate and
not require manual dexterity from users.
For further requirements regarding the accessibility and usability of the interpreter console, see
Annex A.
5.2 Headphones/headset connector
Each interpreter console shall have one non-locking, 3,5 mm headphones/headset connector socket on
each side. It may have an additional, non-locking, 6,35 mm headphones connector socket.

For ergonomics purposes, the console inclination shall be between 15° and 45°.
5.4 Indicator lights
Indicator lights shall be confined to primary functions (microphone “ON,” channel selected, channel
occupied/engaged, etc.) and shall be in the immediate vicinity of the corresponding controls.
The microphone “ON” light shall be evident to anyone present in the booth, without disturbing the
occupants. It shall be the only red indicator light; all other indicator lights shall use colours other
than red. In addition, the microphone shall have an on-air indicator light which shall be red when the
microphone is switched on.
Where a “power-on” indicator is provided, it shall be unobtrusive.
5.5 Buttons
The buttons shall be laid out so that they correspond with the information and content they control
and be arranged in hierarchical order or in a sequence which will aid recognition and use in accordance
with ISO 9241-410.
Buttons should protrude in depth from the surface and have, where possible, a diameter/width of
10 mm or greater. When a button is pressed, a clear haptic feedback shall be produced.
Groups of buttons should have tactile markings that aid identification and navigation, according to
ISO 24503.
The number of buttons required to use the console should take into account the need to avoid excessive
complexity and confusion.
5.6 Visual display
If the console includes a display screen, it shall be non-reflective and legible at the intended viewing angle.
The tilt of the display shall permit an ergonomically sound gaze angle and head tilt angle, in accordance
with ISO 9241-303.
Display luminance shall be easily adjustable. The display shall be designed to provide good visual
ergonomics and a good luminance contrast across a variety of lighting conditions (darkened meeting
room, low lighting in the booth, normal office lighting conditions, direct sunlight).
For light-emitting (active) displays, the foreground to background luminance should have a contrast
ratio of 6:1 or higher.
Character height should be 10mm for perpendicular viewing. If the user is looking at an angle, character
height should be increased accordingly.
Colour combinations should be considered carefully. When using colour to provide information,
information shall also be provided using non-colour methods.

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 20109 was prepared by Technical Committee ISO/TC 37, Terminology and other language and content
resources, Subcommittee SC 5, Translation, interpreting and related technology.
This International Standard is one in a series of four, together with:
— ISO 2603, Simultaneous interpreting — Permanent booths — Requirements
— ISO 4043, Simultaneous interpreting — Mobile booths — Requirements
— ISO 20108, Simultaneous interpreting — Quality and transmission of sound and image input —
Requirements

Introduction
This International Standard specifies the components of typical interpreting equipment, which
together with either permanent (ISO 2603) or mobile (ISO 4043) booths, form the interpreter’s
working environment.
Interpreting equipment, included until the 1998 version in ISO 2603, and referred to in ISO 4043, has
now found its place in this International Standard, together with other elements indispensable for the
interpreter’s working environment, like screens and chairs.
The following auxiliary verbs used in this International Standard have the conventional usage assigned
to them by the ISO directives:
— shall – is used to indicate requirements strictly to be followed in order to conform to the document
and from which no deviation is permitted,
— should – is used to indicate that, among several possibilities one is recommended as particularly
suitable, without mentioning or excluding others, or that a certain course of action is preferred but
not necessarily required,
— may – is used to indicate a course of action permissible within the limits of the document,
— can – is used for statements of possibility and capability, whether material, physical or causal.

For ergonomics purposes, the console inclination shall be between 15° and 45°.
5.4 Indicator lights
Indicator lights shall be confined to active functions (microphone “ON”, channel selected, channel
occupied/engaged, etc.) and shall be in the immediate vicinity of the corresponding controls.
The microphone “ON” light shall be evident to anyone present in the booth, without disturbing the
occupants. It shall be the only red indicator light; all other indicator lights shall use colours other than
red. In addition, the microphone itself shall have an on-air indicator light.
Where a “power-on” indicator is provided, it should be unobtrusive.
5.5 Buttons
The buttons shall be laid out so that they correspond with the information and content they control and
be arranged in hierarchical order or in a sequence which will aid recognition and use (in accordance
with ISO 9241-410).
Buttons should protrude in depth from the surface and have, where possible, a diameter/width of
10 mm or greater. When a button is pressed, a clear haptic feedback shall be produced.
Groups of buttons should have tactile markings that aid identification and navigation (ISO 24503).
The number of buttons required to use the console should take into account the need to avoid
overcomplexity and confusion.
5.6 Visual display
If the console includes a display screen, it shall be non-reflective and legible at the intended viewing angle.
The tilt of the display shall permit an ergonomically sound gaze angle and head tilt angle, in accordance
with ISO 9241-303.
