Key takeaway
Simultaneous Interpretation Systems for Vellore’s biggest events
Interpretation is a standards-driven discipline, and the standards exist because interpreters working in bad conditions make mistakes. Mobile booths are built to ISO 4043, which specifies a working space of roughly 1.6 by 1.6 by 2.0 metres for two interpreters, sound insulation from the floor and from adjacent booths, forced ventilation with a defined air change rate that is quiet enough not to intrude on the microphone, and a full-width front window with unobstructed sight of the speaker, the screen and the delegates. Permanently installed booths follow ISO 2603, and the equipment itself — consoles, headphones, microphones — follows ISO 20109. Where a client asks us to put interpreters in a curtained corner, we decline, because sightline and sound isolation are not optional extras.
Booth siting is the whole design problem: interpreters need direct sight of speaker and screen, while infrared radiators need line of sight to every seat around pillars and balconies. In Vellore that plays out at venues like VIT Anna Auditorium, Hotel Darling Residency, Vellore Fort grounds, and across Katpadi, Sathuvachari, Gandhi Nagar, Bagayam.
Distribution to delegates is almost always infrared on a Bosch Integrus or equivalent system, for one reason that matters more than audio quality: infrared does not pass through walls, so a confidential session cannot be received from the corridor. Radiators are placed to cover the seating area with line of sight to every receiver, and coverage is calculated from radiator power against the room area, with careful attention to shadowing behind pillars, under balconies and in deep seating. Channel planning allocates one channel per target language plus the floor language, and the carrier frequencies are chosen to avoid interference from certain LED and plasma lighting that radiates in the infrared band.

Local conditions
Producing interpretation equipment in Vellore
Weather & the rig
Interpretation booths are sealed, ventilated boxes holding two people for hours, so ambient heat and the venue's cooling capacity directly affect whether the ISO ventilation requirement can actually be met. Vellore sits in a rain-shadow basin ringed by the Javadi and Yelagiri hills and is one of Tamil Nadu's hottest towns — Apr–Jun regularly runs 40–43°C with a dry furnace wind, which is why the calendar is pushed into Nov–Feb. The northeast monsoon brings the Palar basin's rain in short violent bursts from Oct–Dec. Humidity is low by Tamil standards, which is genuinely kinder to gear, but it makes dust and static the things to manage instead. Apr–Jun dry extreme heat; Oct–Nov northeast-monsoon downpours on open ground.
Power & redundancy
Booths, consoles, radiators and a receiver charging operation all need clean uninterrupted supply, and the charging bank is a surprisingly large overnight load on a thousand-delegate event. TANGEDCO supply to the town and the Ranipet industrial belt is fair. Both CMC and VIT run their own substations and substantial DG farms because hospital and campus continuity demands it, which makes institutional venues the easy ones. The kalyana mandapams are the weak link, with sanctioned loads far below requirement, so DG sizing is routine practice here rather than contingency.
Permits & noise rules
Multilateral and government sessions bring security clearance for crew, controlled access to the booths and recording consent requirements rather than conventional event permissions. Vellore Corporation for the licence and temporary structures, the district SP and city police for assembly and loudspeaker permission, and TNPCB noise rules with the 10 pm limit plus the Madras High Court's directions on amplified sound near hospitals — which in a town built around CMC is a mapped constraint across the Ida Scudder Road and Bagayam areas, not a formality. The ASI Chennai circle governs the Fort. VIT and CMC apply their own campus rules on top of everything civic. There is no airport here, so drone work is a local-police and crowd-safety conversation, with care taken around the hospital helipad.
Load-in & access
Flight-cased booth panels are bulky and need a clear path to a position with sightline to the stage, and receiver distribution has to happen at the entry point before delegates disperse. Vellore is one of the few tier-2 towns servable from two metros — Chennai is 140 km and 2.5–3 hours on NH-48, Bengaluru 210 km and 4 hours — and Katpadi junction handles rail parcel reliably. In town, Officers Line and Katpadi Road congestion and the Fort's narrow approach push load-ins into the 10 pm–6 am window, and VIT's campus has good internal roads but a gated, logged entry that slows a convoy to a crawl.
Season & booking
VIT's festival weeks and its convocation book out every hotel room in Vellore and Katpadi and should be checked before any date is offered. CMC's conference season runs alongside. Pongal lands in mid-January, the Tamil wedding calendar avoids Aadi and Puratassi and clusters in Thai and Panguni, and the Golden Temple at Sripuram and the Jalakandeswarar temple calendar add their own festival dates. Peak demand runs Nov–Feb.
Crew & dispatch
Trucked from Chennai, 3 hours east on NH-48, with Bengaluru 4 hours west as a genuine second source; local crew and consumables held in Vellore, and rail parcel into Katpadi as the fallback. Load-in support covers Sathuvachari, Gandhi Nagar and the rest of the city.
What it costs here
Institutional procurement dominates — tendered, documented, committee-approved and reliably settled, but with little room for premium lines. Medical conference work is grant- and sponsor-funded and tightly budgeted. The wedding market is firmly value-led. What wins here is being the supplier who understands the CMC and VIT approval processes, which is worth more than a creative pitch.
Local expectations
Tamil muhurat timings put many ceremonies in the 5–9 am window, so the ceremony and reception are separate builds on the same day. Nadaswaram and thavil need headroom rather than close miking at level. Medical conferences are judged on something unglamorous — slide legibility, lapel mic reliability and recording quality for CME credit — so projection and audio capture matter more than staging. Tamil-first scripting with English throughout the academic layer.
Specification
Simultaneous Interpretation Systems: technical specification
| Specification | Detail |
|---|---|
| Mobile booth standard | ISO 4043: approximately 1.6 x 1.6 x 2.0 m for two interpreters, insulated and ventilated |
| Built-in booth standard | ISO 2603 for permanently installed booths |
| Equipment standard | ISO 20109 for interpreter consoles, microphones and headphones |
| Distribution | Bosch Integrus infrared, confidential because it does not pass through walls |
| Channel capacity | Up to 16 language channels plus the floor channel on a typical deployment |
| Radiator coverage | Calculated from radiator power against floor area with line of sight to every seat |
| Interpreter staffing | Two interpreters per booth per language, swapping every 20 – 30 minutes |
| Audio feed | Clean direct feed from the console to each booth, never a room microphone |
| Relay interpretation | Pivot language routing where no direct language pair is available |
| Receiver logistics | Issued against delegate ID, counted back, charged overnight and sanitised between sessions |
The operational layer is the part clients underestimate. Interpreters work in pairs per booth and swap roughly every twenty to thirty minutes, because sustained simultaneous interpretation is cognitively unsustainable beyond that — a single interpreter per language is a false economy that degrades the session. They need the speaker's slides and script in advance, a clean direct audio feed from the console rather than a room microphone, and a technician who can patch relay interpretation when a language pair has no direct interpreter. Receivers are issued against delegate identification, counted back, charged overnight and sanitised between sessions, which is a logistics job in its own right at scale.

Venues
Where we work in Vellore
| Venue | Capacity | Production note |
|---|---|---|
| VIT Anna Auditorium | Roughly 4,000 fixed seats | A genuinely large fixed-seat hall with in-house AV and a university technical team; the constraint is institutional rather than physical — campus security logging, a student-affairs approval chain, academic-calendar blackouts and an in-house-vendor preference all shape what an external supplier is allowed to touch. |
| Hotel Darling Residency | Up to 600 seated across banquet halls | Vellore's established business hotel on the Katpadi Road side, with a lift-only load-in and a modest banquet ceiling; the forecourt holds one vehicle at a time, so shuttling from a staging point is standard. |
| Vellore Fort grounds | Up to 4,000 inside the moat-ringed grounds | A 16th-century Vijayanagara fort under ASI protection, which sets the terms: no ground penetration, nothing fixed to the masonry, generators staged outside the protected limit, a firm evening finish, and an application to the ASI Chennai circle weeks ahead. |
| CMC Scudder Auditorium and campus halls | 300–1,200 depending on the hall | The default venues for medical conferences; hospital operational priority always wins, so load-in windows are short and fixed, generators and noise are tightly controlled, and crew movement is restricted to approved routes. |
| Katpadi Road kalyana mandapam belt | 800–2,500 across function halls | The volume wedding stock: large covered halls with pillars through the span that break sightlines and truss runs, and sanctioned loads around 50–75 kVA against show requirements well above that, so a DG and its placement are the first decisions. |

Risk control
What goes wrong, and how we stop it
What can go wrong
How we prevent it
- What can go wrong
Infrared coverage drops behind a pillar or under a balcony and a block of delegates hears silence.
How we prevent itRadiator placement is calculated against the seating plan and then physically walked with a receiver at build, with an extra radiator held for the shadow that is always discovered.
- What can go wrong
A single interpreter is booked per language to save cost and quality collapses after half an hour.
How we prevent itWe quote two interpreters per booth per language as standard and explain why — sustained simultaneous interpretation beyond roughly thirty minutes is not reliably accurate.
- What can go wrong
Interpreters receive a room microphone feed full of reverberation and struggle to hear the speaker.
How we prevent itEvery booth takes a clean direct feed from the audio console, and the engineer monitors that feed on headphones rather than assuming it is right.
- What can go wrong
A speaker reads from a prepared script at full speed and interpretation falls behind.
How we prevent itScripts and slides go to interpreters at T-2 weeks, and the chair is briefed to remind speakers that they are being interpreted, which is the single most effective intervention available.
Honest comparison
Is this the right choice for your event?
- Remote simultaneous interpretation instead of on-site boothsOur verdict
RSI is dramatically cheaper, removes booth logistics and gives access to interpreters anywhere. It depends entirely on connectivity and on the interpreter having a clean feed and good sightlines on video, which is fine for a routine webinar and genuinely risky for a high-stakes multilateral session.
- Consecutive interpretation instead of simultaneousOur verdict
Consecutive needs no booths, no receivers and no equipment — the interpreter speaks after the speaker pauses. It roughly doubles the length of every session, which is acceptable for a bilateral meeting and impossible for a full-day agenda.
- Radio or Wi-Fi distribution instead of infraredOur verdict
Radio and app-based distribution cover more area and need no line of sight, which solves the shadowing problem. They also pass through walls, so a confidential session can be received outside the room — which is exactly why government and multilateral work stays on infrared.
