Cinema and multiplex soundproofing in Bengaluru
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. Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
- 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.

01 / What it is
The material, and what it actually does on a Bengaluru 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.
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Work reaching us from Bengaluru is mostly tech campuses, apartment towers, microbreweries and restaurants, clinics, schools, studios.
- Floors full of simultaneous calls Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
- Campus scale repetition The same detail across many floors and buildings. Consistency across a large order matters more than the headline figure on one sheet.
- Microbreweries and hard rooms Exposed brick, steel and glass by design, then packed at capacity. The ceiling plane is usually the only surface left to work with.
- 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 Bengaluru.
02 / The build-up
The build-up, layer by layer
-
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 Bengaluru, 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 carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Bengaluru, auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bengaluru, large engineering and school campuses with lecture halls, seminar rooms and hostels repeating the same detail across many blocks.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
The Bengaluru conditions that change the answer
- Floors full of simultaneous calls
Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
- Campus scale repetition
The same detail across many floors and buildings. Consistency across a large order matters more than the headline figure on one sheet.
- Microbreweries and hard rooms
Exposed brick, steel and glass by design, then packed at capacity. The ceiling plane is usually the only surface left to work with.
- Mild climate, sealed buildings
Air conditioned floors stay closed, so sound accumulates rather than escaping. Absorption has to be balanced, not maximised.
- Assembly and performance rooms
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
04 / Room by room
Where the money goes on a Bengaluru project
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic carpet and rugs, High density polyester
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. The same detail across many floors and buildings. Consistency across a large order matters more than the headline figure on one sheet.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic carpet and rugs, Felt
-
Plant and projection
Equipment noise into the auditorium, treated at source. Exposed brick, steel and glass by design, then packed at capacity. The ceiling plane is usually the only surface left to work with.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Acoustic carpet and rugs, 64 sq ft per pack
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
What the Bengaluru climate rules in and rules out
Bengaluru 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 Bengaluru project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
A shared service void running across the wall line
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
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 Bengaluru job
Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
05 / Route to site
Getting it to Bengaluru, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four to five days |
| Dispatch | 2 to 4 working days |
| To site | four to five 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 twenty one hundred kilometres, normally four to five days on a dedicated truck.
Questions from Bengaluru projects
What makes cinema and multiplex soundproofing different in Bengaluru?
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey. Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
Where should the budget go first on a Bengaluru 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 Bengaluru?
No. We manufacture in India and supply into Bengaluru. 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 Bengaluru site?
made at: Our own plant, Palwal, Haryana, reaches site in: four to five 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.
Next step
Send a plan and a section, get a real build-up
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
