Auditorium acoustics and soundproofing in Hong Kong
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem. Church buildings, halls and function rooms are compact hard volumes carrying amplified speech.
- Reverberation time
- Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
- Early reflections
- Shaped surfaces that send energy to the rear seats rather than absorbing everything.
- Rear wall
- The single worst surface in most halls, and the first one to treat.

01 / The material
What you are buying, and what it fixes in Hong Kong
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem.
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.
- Reverberation time Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for auditorium acoustics are on the main product page. This page covers what that means for a project in Hong Kong.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Hong Kong, central plant, split units and VRF packed into light wells and podium decks close to every flat.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Hong Kong, church buildings, halls and function rooms are compact hard volumes carrying amplified speech.
Feature wall only. Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Hong Kong, school buildings are compact and hard surfaced with very intensive use and no spare volume.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What the buildings in Hong Kong do to the specification
- 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.
- School and campus buildings
School buildings are compact and hard surfaced with very intensive use and no spare volume.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. 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.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Cooling plant sits within metres of windows in a dense city, so plant noise reaches more people than any single source.
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
The Hong Kong climate decides the material list
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.
On a Hong Kong job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
Absorbing the whole room and losing the back rows
This is the one that comes back as a second fit-out rather than a snag.
-
Adding speakers to fix a reverberation problem
It sounds like a small detail until the room is finished and the complaint arrives.
-
Ignoring the rear wall because it is behind the audience
This is the one that comes back as a second fit-out rather than a snag.
-
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 / Supply
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 auditorium acoustics and 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?
Reverberation time. Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Early reflections. Shaped surfaces that send energy to the rear seats rather than absorbing everything.
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?
Absorbing the whole room and losing the back rows. Adding speakers to fix a reverberation problem.
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.

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.
