Cinema and multiplex soundproofing in Kolkata
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes. Auditoria, community halls and pandal spaces carry amplified speech and music at high level.
- Screen to screen
- Independent construction between auditoria, with services broken at the line.
- In room response
- Heavy absorption on side and rear walls so the mix is heard as intended.
- Plant and projection
- Equipment noise into the auditorium, treated at source.

The material, and what it actually does on a Kolkata job
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes.
Auditoria, community halls and pandal spaces carry amplified speech and music at high level.
Work reaching us from Kolkata is mostly old buildings and conversions, offices, clubs and restaurants, schools, clinics, auditoriums.
- Tall rooms, hard plaster High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
- Timber floors between floors Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- The structure is staying Conversions here keep the original fabric, so the work has to be internal, shallow and ideally reversible.
- Screen to screen Independent construction between auditoria, with services broken at the line.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for cinema soundproofing are on the main product page. This page covers what that means for a project in Kolkata.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Kolkata, split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 2
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Kolkata, auditoria, community halls and pandal spaces carry amplified speech and music at high level.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Kolkata, long established schools and colleges in masonry with high ceilings and very large class sizes.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
If you are specifying for a Kolkata project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / On the ground
The Kolkata conditions that change the answer
- Tall rooms, hard plaster
High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
- Timber floors between floors
Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- The structure is staying
Conversions here keep the original fabric, so the work has to be internal, shallow and ideally reversible.
- Humid most of the year
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Assembly and performance rooms
Auditoria, community halls and pandal spaces carry amplified speech and music at high level.
04 / Room by room
Where the money goes on a Kolkata project
-
Screen to screen
Independent construction between auditoria, with services broken at the line. High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
- Acoustic carpet and rugs, 4 mm
- PET felt acoustic panels, 4 to 24 mm
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Acoustic carpet and rugs, High density polyester
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. Conversions here keep the original fabric, so the work has to be internal, shallow and ideally reversible.
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Acoustic carpet and rugs, Felt
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate
The Kolkata climate decides the material list
Kolkata is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
Where a consultant is already engaged on a Kolkata project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
A shared service void running across the wall line
A treated wall under a bare hard ceiling gives you a fraction of the reduction you paid for, and the room still sounds wrong.
-
Treating the auditorium to fix bleed from the next screen
This is the one that comes back as a second fit-out rather than a snag.
-
Doors and lobbies specified late and undersized
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Treating it as a generic Kolkata job
High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
05 / Route to site
How material reaches a Kolkata site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three days |
| Dispatch | 2 to 4 working days |
| To site | three days |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly fourteen hundred kilometres, normally three days on a dedicated truck.
Questions from Kolkata projects
What makes cinema and multiplex soundproofing different in Kolkata?
Auditoria, community halls and pandal spaces carry amplified speech and music at high level. High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
Where should the budget go first on a Kolkata project?
Screen to screen. Independent construction between auditoria, with services broken at the line. In room response. Heavy absorption on side and rear walls so the mix is heard as intended.
Do you have an office or installation team in Kolkata?
No. We manufacture in India and supply into Kolkata. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Kolkata site?
made at: Our own plant, Palwal, Haryana, reaches site in: three days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
What goes wrong most often on this kind of project?
A shared service void running across the wall line. Treating the auditorium to fix bleed from the next screen.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
