Home theatre soundproofing and acoustics in China
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. Reinforced concrete towers with block infill and hard floors. Mass is good, impact noise through the slab and between flats is the complaint.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.

01 / The material
What this material is and where it earns its place in China
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
Reinforced concrete towers with block infill and hard floors. Mass is good, impact noise through the slab and between flats is the complaint.
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.
- Containment Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in China.
02 / The build-up
What goes where, from the structure in
-
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 foam and BassBloc
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing. In China, auditoria, conference centres and function halls are large hard volumes with long decay.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In China, school buildings are concrete and tile with very large class sizes and long hard corridors.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
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
What the buildings in China do to the specification
- 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.
- The housing stock
Reinforced concrete towers with block infill and hard floors. Mass is good, impact noise through the slab and between flats is the complaint.

Where the money goes on a China project
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. 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
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Soundproof curtains, 5.5 kg per sq m
-
Low frequency inside
Corner absorption with depth, before any surface treatment. The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Soundproof curtains, Up to 30 dB
-
Reflections
Side wall and ceiling first reflection points at the seating position. 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
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Soundproof curtains, 30
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 / Durability
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.
On a China job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Straight talk
What we watch go wrong on jobs like this
-
Foam on the walls as a soundproofing measure
Small on the drawing, expensive on site, and almost always found after handover.
-
A standard door on a room built to hold bass
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating before the room is sealed
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
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
How material reaches a China site
| 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 home theatre soundproofing and acoustics different in China?
Reinforced concrete towers with block infill and hard floors. Mass is good, impact noise through the slab and between flats is the complaint. 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?
Containment. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
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?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
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.
