Hospital and healthcare acoustics in China
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, VRF and split units, with risers and duct runs carrying noise between floors.
- 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.

What you are buying, and what it fixes in China
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, VRF and split units, with risers and duct runs carrying noise between floors.
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.
- 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 China.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In China, central plant, VRF and split units, with risers and duct runs carrying noise between floors.
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 China, auditoria, conference centres and function halls are large hard volumes with long decay.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
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 China, school buildings are concrete and tile with very large class sizes and long hard corridors.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
Architects working in China 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 / In this market
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.
- Plant and HVAC
Central plant, VRF and split units, with risers and duct runs carrying noise between floors.

Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. 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.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Ward noise floor
Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling. The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.
- Ceiling baffles and clouds, 9 to 24 mm
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic panels, ASTM C423
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Where a single project runs across many floors, batch to batch consistency is usually the reason people come to a single manufacturer.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
For a China interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate
The China climate decides the material list
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 / Before you buy
The six errors that cost the most
-
Fabric wrapped products in a clinical area
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Absorption used where privacy was the requirement
If the complaint is being overheard, no amount of absorption inside the room will fix it. That is a partition job and we will say so.
-
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 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 / Getting it there
Supply into China, start to site

|---|---|
| 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 hospital and healthcare acoustics different in China?
Central plant, VRF and split units, with risers and duct runs carrying noise between floors. 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?
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 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?
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.

Drawings in, BOQ and a delivered date out
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.
