Introduction
This document concerns permanent booths for simultaneous interpreting which have a direct view to
a conference room.
There are a number of things to be taken into account when designing and building permanent booths.
Interpreting is an activity that requires high levels of concentration, therefore the working environment
has to meet the highest standards to minimize stress.
This document addresses the following:
a) workplace setting of interpreters;
b) visual communication between interpreters and participants at an event;
c) sound insulation from the noise transmitted from the booth's environment to a booth.

4 Location
4.1 Conference room characteristics
When new conference rooms are designed, booths shall be integrated into the structure so that the
conference room itself and the booths constitute a well-balanced unit in terms of layout, people flow
within buildings, accessibility and usability according to ISO 21542.
Conference rooms and booths shall be located away from any sources of disturbance, such as kitchens,
public corridors and passageways.
In order to facilitate speech intelligibility, the conference room should not cause reverberation or
echoes exceeding the values recommended for the type of room according to ASNZS 2107:2000.
NOTE ASNZS 2107:2000 also specifies methods of measuring the background sound level and the
reverberation time in unoccupied spaces.
Booths shall receive as much indirect daylight from the conference room as possible.
Specialized entities or conference interpreters with expert knowledge of booths shall be consulted
from the earliest stages of planning together with suppliers and specialists such as architects and
project engineers.
4.2 Siting and visibility
Booths shall be placed in such a way that the interpreters have a direct view of the entire conference
room, including the rostrum, speakers, signers, and all visual aids such as projection screens and

displays. Booths shall also be situated in such a way that no columns or pillars obstruct the interpreters'
view.
Booths shall be raised above the floor so that the interpreters' view cannot be obstructed by people
standing in the way. Accordingly, the booth floor shall be no less than 60 cm above the room floor,
assuming a level floor.
Booths shall be grouped in such a way as to facilitate visual contact, as well as cabling between them.
If the booths are located to one side of the conference room, the angle of the interpreters’ line of vision
towards a screen should be no less than 35°, taking the edge of the booth as a reference. The purpose of
this is to give the interpreter a clear view without having to bend forward or sideways.
Extended language regimes may require the use of booths on two levels.
In very large rooms, where the rostrum and/or projection screen are more than 20 m away, video
displays (see 6.8) shall be used to provide a view of the speakers if the distance between the booths and
the screen is ≥3 times the screen's diagonal.
Video displays (see 6.8) may also be used in booths situated behind the speakers or on the upper level.
4.3 Access
It shall be possible to quickly, easily and safely access:
— one booth from another booth;
— all booths from the conference room;
— all booths from outside the conference room.
A minimum of 10 % of the booths, rounded up to the next whole number, shall be accessible to persons
with a disability, in accordance with ISO 21542.
4.4 Control unit
The control unit should be placed close to the interpreting booths so that:
— technical support staff can access it easily;
— visual communication between the technical support staff and the interpreters is possible;
— technical support staff have a clear view of the entire conference room, including the rostrum,
speakers, signers and all visual aids such as projection screens and displays.
The control unit may be installed:
— on a table;
— in a rack;
— in a booth that complies with the requirements and recommendations of a permanent booth for
simultaneous interpreting.
If not present in the conference room, a central control unit should be available in the venue.
Interpreters shall be able to communicate directly with the technical support staff who shall have safe,
quick and easy access to the booths and the conference room.

5 Design
5.1 General requirements
Each booth shall accommodate interpreters comfortably seated side by side, each with sufficient table
space to work on (see 6.4) and space to spread documents and place electronic devices.
NOTE Permanent booths providing space for no more than one interpreter are not compliant with this
document.
5.2 Dimensions
The size of a permanent booth (see Figure 1) is governed by the need to provide each interpreter with
sufficient work space, while at the same time allowing them to enter and leave the booth without
disturbing one another. The booth shall also be high enough and deep enough to provide the required
volume of air to enable adequate temperature control and draught-free air renewal (see 5.6).
The following minimum internal dimensions shall apply:
a) width: 2,50 m;
b) depth: 2,40 m;
c) height: 2,30 m.
Different dimensions may apply for a booth for signed language interpreting.
NOTE 1 Good results have been obtained with the following internal dimensions:
d) width: 5,00 m;
e) depth: 4,00 m;
f) height: 2,30 m.
For conference rooms with up to six booths, one or more of them should be at least 3,20 m wide to cover
the need for the continuous presence of three interpreters.
For conference rooms with more than six booths, all booths shall be at least 3,20 m wide.
To avoid resonance effects, the three dimensions of the booth should be different from one another and,
to avoid standing waves, the two side-walls should not be exactly parallel.
NOTE 2 Where feasible, additional height can assist draught and temperature control.

5.3 Doors
See Figure 1.
The doors shall be hinged, operate silently and provide satisfactory acoustic insulation (see 5.5.1).
They shall have a handle, but no latch, and shall close automatically and silently. The threshold shall not
exceed 2 cm.
There shall be either a light outside the door to indicate that a microphone is on inside the booth, or an
observation porthole of no less than 20 cm × 20 cm in the door.
There shall be no doors between booths. Doors shall be no less than 85 cm wide in accordance with
ISO 21542. Wheelchair access to the workplace may be regulated.
Sliding doors, curtains or baffles shall not be used instead of doors.
5.4 Windows
Each booth, including the control booth, shall have front and side windows (see Figure 1).
NOTE Booths adjacent to the side wall of the conference room do not need to have windows on both sides.
The front window shall consist of a single uninterrupted pane of glass and span the full width of the
booth. It shall extend upwards for at least 1,20 m from the work surface (see 6.4).
For upper-level booths, the windows should be adapted to guarantee an ergonomic gaze-angle and a
view of the conference room that is as complete as possible. The lower edge of the front window may
therefore be lower than the work surface (see Figure 2).

Side windows, of at least the same height as the front window, shall extend from the front window for at
least 1,10 m along the partition between booths.
To ensure an unobstructed view from the booths, there shall be no vertical supports dividing the panes.
Front and side windows shall be made of colourless, anti-glare glass that meets sound insulation
requirements (see 5.5.1). The panes shall be mounted in such a way as to avoid vibration and reflections
from the conference room and the booth lighting.
Depending on the type of work lighting used (see 6.3) and for acoustic reasons (5.5.1), front panes may
have to be inclined.
If booth windows are curved, they shall not distort the view.
