How an interpreting chain works
The speaker's microphone sends sound to the interpreter's console inside a soundproof booth. The interpreter speaks into their own microphone; their voice is broadcast on a radio or infrared channel, which each participant picks up with a receiver and headset. One language equals one channel.
Any weak link shows immediately: a badly placed speaker microphone makes interpreting approximate, a poorly insulated booth creates interference, an uncharged receiver dies mid-session. That is why we test everything beforehand.
ISO standards
Two international standards apply: ISO 2603 for permanent booths and ISO 4043 for mobile ones. They cover four essentials: working space for two interpreters, continuous silent ventilation, acoustic insulation in both directions, and a clear view of the speaker and screen.
These are not comfort requirements. Poor ventilation raises CO₂ levels and measurably reduces alertness; no line of sight means the interpreter cannot read lips or follow slides. Our mobile booths comply with ISO 4043 and certificates are available on request.
