Cinema and multiplex soundproofing in Hosur
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. Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
- 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 material
What you are buying, and what it fixes in Hosur
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.
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Work reaching us from Hosur is mostly electronics and automotive plants, test and QC rooms, offices, canteens, training rooms, hostels.
- New plants, decisions still open On a greenfield build the enclosure and the partition can be designed in, which costs a fraction of fixing it after commissioning.
- Test and clean areas QC and measurement rooms need a low background before any result means anything. That is isolation with a written target.
- Canteens and training rooms Large hard rooms where hundreds of people eat or listen. Ceiling absorption does almost all of the work.
- 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 Hosur.
02 / The build-up
The stack, in the order it is installed
-
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 Hosur, 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.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
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 Hosur, kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
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 Hosur, very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
The Hosur conditions that change the answer
- New plants, decisions still open
On a greenfield build the enclosure and the partition can be designed in, which costs a fraction of fixing it after commissioning.
- Test and clean areas
QC and measurement rooms need a low background before any result means anything. That is isolation with a written target.
- Canteens and training rooms
Large hard rooms where hundreds of people eat or listen. Ceiling absorption does almost all of the work.
- Four to five days by road
A dedicated truck from Palwal, with samples sent ahead so the finish is approved before the order.
- Assembly and performance rooms
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.

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 / Durability
The Hosur climate decides the material list
Hosur 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 Hosur project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
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
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 Hosur job
On a greenfield build the enclosure and the partition can be designed in, which costs a fraction of fixing it after commissioning.
05 / Getting it there
Supply into Hosur, start to site
| 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 two thousand two hundred kilometres, normally four to five days on a dedicated truck.
Questions from Hosur projects
What makes cinema and multiplex soundproofing different in Hosur?
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music. On a greenfield build the enclosure and the partition can be designed in, which costs a fraction of fixing it after commissioning.
Where should the budget go first on a Hosur 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 Hosur?
No. We manufacture in India and supply into Hosur. 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 Hosur 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
Drawings in, BOQ and a delivered date out
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
