(Main)Simultaneous interpreting - Interpreters’ working environment - Part 1: Requirements and recommendations for permanent booths (ISO 17651-1:2024)
General Information
- Abstract
This document specifies requirements and recommendations for the design of permanent booths for simultaneous interpreting in new or existing buildings. This document also ensures the usability and accessibility of booths for all interpreters.
This document is to be used in conjunction with ISO 20109, which contains requirements and recommendations for the equipment necessary for simultaneous interpreting. For requirements and recommendations for permanent booths which do not have a direct view of the room in which a communicative event takes place, see ISO 17651-3.[1]

Overview
EN ISO 17651-1:2024 - Simultaneous interpreting - Interpreters’ working environment - Part 1: Requirements and recommendations for permanent booths - specifies design, usability and accessibility principles for permanent interpretation booths in new or existing buildings. It replaces EN ISO 2603:2016 and is intended to be used together with ISO 20109 (equipment requirements) and, for booths without a direct view, the forthcoming ISO 17651-3. The standard was prepared by ISO/TC 37 in collaboration with CEN and is adopted as a European Standard.
Key topics and technical requirements
The standard covers practical, technology-neutral requirements and recommendations across booth lifecycle and fit-out, including:
- Location & siting
- Room characteristics, visibility of the event, accessibility and proximity to technical support.
- Design & dimensions
- General layout principles, recommended booth dimensions, door and window considerations to support sightlines and usability.
- Acoustics
- Sound insulation and sound absorption objectives to protect concentration and ensure audio quality for interpreters and listeners.
- HVAC (Heating, ventilation and air conditioning)
- Air quality, temperature, humidity and airflow guidance plus acoustic treatment of HVAC systems to avoid noise ingress.
- Electrical & data
- Power supply, cable ducts, internet access and electromagnetic radiation limits to support interpreting equipment and digital connectivity.
- Booth interior
- Lighting, colour schemes, work surfaces, furniture, video displays, storage and special requirements for signed language interpreters.
- Amenities
- Provision of toilets and interpreters’ break rooms to support well‑being and shift rotation.
- Accessibility & usability
- Design that ensures booths are accessible to all interpreters (including mobility and visual needs).
Practical applications and target users
EN ISO 17651-1:2024 is practical for:
- Architects and building designers specifying conference and public building spaces
- Acoustic and AV engineers integrating interpretation systems
- Venue owners and facility managers (conference centres, parliaments, courts, international organizations)
- Conference organisers and interpreter service providers setting up booths that meet professional and accessibility standards
- Standards bodies and procurement teams referencing compliance in tenders
Related standards & notes
- Use together with ISO 20109 (interpretation equipment requirements).
- See ISO 17651-3 for booths without direct view (under preparation).
- The document is technology-neutral and reflects recent technological developments in interpreting environments.
