Cinema and multiplex soundproofing in Hong Kong
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. Church buildings, halls and function rooms are compact hard volumes carrying amplified speech.
- 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 this material is and where it earns its place in Hong Kong
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.
Church buildings, halls and function rooms are compact hard volumes carrying amplified speech.
Work reaching us from Hong Kong is mostly apartments, offices, hotels and dining, clinics, schools, studios.
- Depth is the expensive part Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost.
- Concrete towers, live rooms The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer.
- Plant on every roof and podium Cooling plant sits within metres of windows in a dense city, so plant noise reaches more people than any single source.
- 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 Hong Kong.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Hong Kong, central plant, split units and VRF packed into light wells and podium decks close to every flat.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 2
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 Hong Kong, church buildings, halls and function rooms are compact hard volumes carrying amplified speech.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Hong Kong, school buildings are compact and hard surfaced with very intensive use and no spare volume.
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 Hong Kong project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What decides the build-up in Hong Kong
- Depth is the expensive part
Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost.
- Concrete towers, live rooms
The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer.
- Plant on every roof and podium
Cooling plant sits within metres of windows in a dense city, so plant noise reaches more people than any single source.
- The port is right here
Direct sea into Hong Kong keeps the chain short and the landed cost predictable.
- Assembly and performance rooms
Church buildings, halls and function rooms are compact hard volumes carrying amplified speech.

What each space in a Hong Kong project needs
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- 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 a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- 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. Cooling plant sits within metres of windows in a dense city, so plant noise reaches more people than any single source.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic carpet and rugs, Felt
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
For a Hong Kong interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Conditions
Durability in Hong Kong, before acoustics is discussed
Hong Kong 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.
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 / Read this first
Six mistakes that turn into a second fit-out
-
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
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic Hong Kong job
Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost.
05 / Route to site
What the route into Hong Kong actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hong Kong, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Hong Kong |
| 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 direct into Hong Kong, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Hong Kong projects
What makes cinema and multiplex soundproofing different in Hong Kong?
Church buildings, halls and function rooms are compact hard volumes carrying amplified speech. Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost.
Where should the budget go first on a Hong Kong 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 Hong Kong?
No. We manufacture in India and supply into Hong Kong. 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 Hong Kong site?
ships from: Palwal, Haryana, India, arrives at: Hong Kong, then a short road run 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
Drawings in, BOQ and a delivered date out
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.
