Hospital and healthcare acoustics in Hong Kong
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed. Central plant, split units and VRF packed into light wells and podium decks close to every flat.
- Consulting room privacy
- Speech privacy between rooms, which is partition, door and ceiling void work.
- Ward noise floor
- Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
- Cleanability
- Non shedding, non absorbent surfaces that survive a cleaning regime.

The material, and what it actually does on a Hong Kong job
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed.
Central plant, split units and VRF packed into light wells and podium decks close to every flat.
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.
- Consulting room privacy Speech privacy between rooms, which is partition, door and ceiling void work.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for healthcare acoustics are on the main product page. This page covers what that means for a project in Hong Kong.
02 / The build-up
What goes where, from the structure in
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Hong Kong, central plant, split units and VRF packed into light wells and podium decks close to every flat.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Hong Kong, church buildings, halls and function rooms are compact hard volumes carrying amplified speech.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
Layer 3
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 Hong Kong, school buildings are compact and hard surfaced with very intensive use and no spare volume.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
Architects working in Hong Kong usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / Local conditions
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.
- Plant and HVAC
Central plant, split units and VRF packed into light wells and podium decks close to every flat.
04 / Room by room
What each space in a Hong Kong project needs
-
Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. 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.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- Acoustic carpet and rugs, 4 mm
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Ward noise floor
Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling. The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer.
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Cooling plant sits within metres of windows in a dense city, so plant noise reaches more people than any single source.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
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.
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 / Straight talk
Where this kind of project usually fails
-
Fabric wrapped products in a clinical area
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Absorption used where privacy was the requirement
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Ceiling void left open above a partition
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 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 / Logistics
Getting it to Hong Kong, with real dates
| 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 hospital and healthcare acoustics different in Hong Kong?
Central plant, split units and VRF packed into light wells and podium decks close to every flat. 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?
Consulting room privacy. Speech privacy between rooms, which is partition, door and ceiling void work. Ward noise floor. Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
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?
Fabric wrapped products in a clinical area. Absorption used where privacy was the requirement.
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
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.
