Key takeaway
Simultaneous Interpretation Systems for Siliguri’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 Siliguri that plays out at venues like Cinnamon Siliguri, Kanchenjunga Stadium, Mayfair Siliguri, and across Sevoke Road, Hill Cart Road, Matigara, Pradhan Nagar.
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 Siliguri
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. Three distinct hazards. Jun–Sep brings Himalayan foothill rain of 2,500 mm-plus with the Mahananda and Teesta running high and Sevoke Road waterlogging. Nov–Jan brings dense Dooars fog that closes Bagdogra for hours and destroys any projection or aerial plan. Worst for a build is Apr–May, when Kalbaishakhi squall lines arrive off the plains with twenty minutes' warning and 60–70 km/h gusts — the single biggest cause of collapsed outdoor structures in north Bengal. Jun–Sep monsoon with its landslide closures on the hill routes; and Apr–May squall season for any outdoor build without a wind plan.
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. WBSEDCL supply has frequent short interruptions and noticeable voltage swing through the wholesale and Sevoke Road belt, so DG with automatic voltage regulation is standard and a stabiliser ahead of LED processors is sensible. Tea-garden and Dooars-edge venues are entirely generator-fed, with fuel carried in because the estate roads make a mid-show bowser run unrealistic.
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. Siliguri Municipal Corporation for the licence and temporary-structure permission, the Siliguri Police Commissionerate for the public-performance and loudspeaker licence, and West Bengal Pollution Control Board noise rules with the 10 pm outdoor limit — Bengal's enforcement spikes around Kali Puja and Diwali, when the sound-box crackdown is active and genuine. Bagdogra is a civil enclave on an Air Force base 13 km out, which effectively closes drone operations. International-border proximity means the district administration expects intimation for any large gathering.
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. Siliguri is unusually easy to supply for its size because NJP railhead and Bagdogra air cargo both work — Kolkata is 560 km and 11–12 hours, so heavy LED and truss generally rail or fly rather than drive. Onward hill work is the hard part: NH-10 along the Teesta towards Kalimpong and Gangtok has landslide closures and a practical vehicle-length limit, and the Darjeeling road needs small trucks and tempo travellers only. Plan a transfer at Siliguri rather than a through-run.
Season & booking
Durga Puja and Kali Puja in Sep–Oct are absolute — every sound box, dimmer, truss span and technician in the district is committed to pandals for a fortnight, and anything else booked in that window will not be serviced. The Christmas–New Year hill-tourist peak locks accommodation and vehicles. Add the Teesta Tea and Tourism Festival, Saraswati Puja in Jan–Feb, and the Bengali wedding dates clustered in Agrahayan and Magh. Peak demand runs Oct–Mar.
Crew & dispatch
Local crew with working stock in Siliguri; large-format LED and specialist inventory railed to NJP or flown into Bagdogra from Kolkata rather than driven, with at least 48 hours in hand for the handover. Load-in support covers Pradhan Nagar, Champasari and the rest of the city.
What it costs here
Trading-family weddings pay well for visible spend — stage, floral, LED and entry — and negotiate hard on crew days and infrastructure. Tea-industry and corporate roadshow work is modest in value but reliably repeating across a season. The cost of getting gear here at all has to sit honestly in the quote, because freight and the hill transfer are not absorbable.
Local expectations
A genuinely mixed market — Marwari weddings run a long multi-day sequence with sangeet at full volume, Bengali weddings keep the shehnai, conch and uludhwani in acoustic space, and both expect the curfew honoured because Bengal police act on it. Pandal work answers to a puja committee, so the plan is presented to a room. Bengali and Hindi announcements with Nepali recognised in the hill-adjacent crowd.
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 Siliguri
| Venue | Capacity | Production note |
|---|---|---|
| Cinnamon Siliguri | Up to 900 seated across banquet halls | Sevoke Road property with a workable approach but no real dock — unloading happens on the service side of a busy arterial, and the hall's beam-to-slab gap keeps the lighting trim low. |
| Kanchenjunga Stadium | 20,000-plus with the field in use | The city's main large-crowd venue, right in the centre: no permanent rigging, turf and track protection needed before any vehicle crosses, a single usable service gate, and a surrounding commercial block where the approach jams solid by 9 am. |
| Mayfair Siliguri | Up to 800 across ballroom and lawns | Resort-format property on the Matigara side with lawn space and parking; the open lawn is exposed to the pre-monsoon squall line, so anything tall here needs guying and a wind-abort trigger written into the plan. |
| Sinclairs Siliguri | Up to 500 seated across halls | Established Pradhan Nagar hotel sized for conferences and mid-scale receptions; load-in is lift-based from a tight forecourt and parking is the practical limit on how many vehicles can be on site at once. |
| Tea-garden and Dooars-edge venues | 300–1,500 depending on the estate | The estate bungalow-and-lawn settings that destination clients ask for sit outside the municipal supply area entirely, so they are DG-only, the estate roads will not take a heavy truck after rain, and the Forest Department takes an interest wherever the plot abuts an elephant corridor. |

Risk control
What goes wrong, and how we stop it
What can go wrong
How we prevent it
- What can go wrong
Receivers go missing because they were handed out without reconciliation.
How we prevent itIssue against delegate identification, a count at every break, and a documented reconciliation at session end — at a thousand units the loss rate without this is material.
- 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.
Honest comparison
Is this the right choice for your event?
- A curtained corner instead of an ISO 4043 boothOur verdict
There is no honest case for it on a session that matters. The booth exists to isolate the interpreter's own voice from the floor audio and to give them sight of the speaker; without both, accuracy falls and the delegates hear the result.
- 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.
