Short definition
ISO 2603:2016 sets the requirements for permanently installed interpreting booths – covering sound isolation, dimensions, sightlines, lighting, and ventilation.
Detailed explanation
ISO 2603, titled "Simultaneous interpreting – Permanent booths – Requirements," is aimed at anyone planning, building, or renovating permanently installed booths – architects, planners, operators, and interpreters. The standard ensures the booth meets three core goals: acoustic separation of languages without mutual interference, reliable two-way communication between booth and hall, and a comfortable working environment for the highly concentrated work of interpreting.
Specifically, it sets requirements for sound insulation and absorption, booth dimensions for two or more interpreters, lighting, heating, and ventilation, as well as placement in the conference room – with a clear view of speakers and screen and without disruptive noise. Together with ISO 20108 (video/audio quality) and ISO 20109 (equipment), it forms the normative framework for fixed interpreting stations.
Relevance in this subject area
For any permanent conference room requiring interpreting, ISO 2603 is the benchmark. It distinguishes a professionally planned booth from an acoustically unsuitable installation.
Practical example
A congress center installs two permanent interpreting booths. Architect and acoustician plan dimensions, insulation, and sightlines according to ISO 2603 – ensuring both booths are standard-compliant and usable long-term.
