Cinema and multiplex soundproofing in Salem
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 product
What this material is and where it earns its place in Salem
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 Salem is mostly steel and textile plant, workshops, offices, canteens, colleges, hospitals.
- Plant noise is a mass problem Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.
- Hot buildings PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process.
- Intelligibility on the floor Large sheds where instructions and alarms have to be understood. Targeted absorption fixes that without touching the machines.
- 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 Salem.
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 Salem, 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 Salem, kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Salem, very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
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 / In this market
What decides the build-up in Salem
- Plant noise is a mass problem
Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.
- Hot buildings
PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process.
- Intelligibility on the floor
Large sheds where instructions and alarms have to be understood. Targeted absorption fixes that without touching the machines.
- Five days by road
A long run, confirmed before dispatch, with samples sent ahead.
- Assembly and performance rooms
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.

Where the money goes on a Salem project
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.

- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process.

- Acoustic panels, ASTM C423
-
Plant and projection
Equipment noise into the auditorium, treated at source. Large sheds where instructions and alarms have to be understood. Targeted absorption fixes that without touching the machines.
- 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 panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate
What the Salem climate rules in and rules out
Salem 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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
A shared service void running across the wall line
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
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 Salem job
Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.
05 / Logistics
What the route into Salem actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | 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 three hundred kilometres, normally five days on a dedicated truck.
Questions from Salem projects
What makes cinema and multiplex soundproofing different in Salem?
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music. Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.
Where should the budget go first on a Salem 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 Salem?
No. We manufacture in India and supply into Salem. 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 Salem site?
made at: Our own plant, Palwal, Haryana, reaches site in: 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
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
