Cinema and multiplex soundproofing in China
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, conference centres and function halls are large hard volumes with long decay.
- 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 China 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, conference centres and function halls are large hard volumes with long decay.
Work reaching us from China is mostly specification-led projects, international hotel and office fit-out, studios, showrooms.
- We are not the default here Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
- Concrete towers, hard interiors The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.
- Colour across a large order Where a single project runs across many floors, batch to batch consistency is usually the reason people come to a single manufacturer.
- 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 China.
02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In China, central plant, VRF and split units, with risers and duct runs carrying noise between floors.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 China, auditoria, conference centres and function halls are large hard volumes with long decay.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In China, school buildings are concrete and tile with very large class sizes and long hard corridors.
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 China 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 China conditions that change the answer
- We are not the default here
Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
- Concrete towers, hard interiors
The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.
- Colour across a large order
Where a single project runs across many floors, batch to batch consistency is usually the reason people come to a single manufacturer.
- Well served ports
Shanghai, Ningbo and Shenzhen all run frequently from India, so routing is straightforward.
- Assembly and performance rooms
Auditoria, conference centres and function halls are large hard volumes with long decay.
04 / Room by room
Where the money goes on a China project
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- 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. The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.

- 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. Where a single project runs across many floors, batch to batch consistency is usually the reason people come to a single manufacturer.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m

- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
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
Why the climate in China changes the material, not the target
China 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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on 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
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 China job
Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
05 / Logistics
Getting it to China, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Shanghai, Ningbo or Shenzhen, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Shanghai or Ningbo |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Shanghai, Ningbo or Shenzhen, then road to site. Air freight for samples and urgent quantities.
Questions from China projects
What makes cinema and multiplex soundproofing different in China?
Auditoria, conference centres and function halls are large hard volumes with long decay. Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
Where should the budget go first on a China 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 China?
No. We manufacture in India and supply into China. 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 China site?
ships from: Palwal, Haryana, India, arrives at: Shanghai, Ningbo or Shenzhen, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. 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
Tell us the room, we will tell you the build-up
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
