Cinema and multiplex soundproofing in Patna
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 / The product
What you are buying, and what it fixes in Patna
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 Patna is mostly coaching institutes and colleges, hospitals, government buildings, auditoriums, offices, hotels.
- Rooms built for listening Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing.
- New institutional build Concrete and tile put up quickly, with acoustics discovered at handover. Early drawings are worth more than extra material later.
- Medical privacy Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.
- 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 Patna.
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 Patna, 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 Patna, 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.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Patna, large government and private schools in concrete and tile with very large class sizes and open corridors.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
If you are specifying for a Patna 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
What we see driving Patna briefs
- Rooms built for listening
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing.
- New institutional build
Concrete and tile put up quickly, with acoustics discovered at handover. Early drawings are worth more than extra material later.
- Medical privacy
Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.
- Two days by road
A manageable run, so freight is reasonable and samples arrive before the order is placed.
- 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.

Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate and durability
Durability in Patna, before acoustics is discussed
Patna is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
On a Patna job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Read this first
What we watch go wrong on jobs like this
-
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
Small on the drawing, expensive on site, and almost always found after handover.
-
Doors and lobbies specified late and undersized
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.
-
Treating it as a generic Patna job
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing.
05 / Supply
How material reaches a Patna site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two days |
| Dispatch | 2 to 4 working days |
| To site | two 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 ten hundred kilometres, normally two days on a dedicated truck.
Questions from Patna projects
What makes cinema and multiplex soundproofing different in Patna?
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. Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing.
Where should the budget go first on a Patna 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 Patna?
No. We manufacture in India and supply into Patna. 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 Patna site?
made at: Our own plant, Palwal, Haryana, reaches site in: two 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.
