Home theatre soundproofing and acoustics in South Korea
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 apartment towers with underfloor heating and hard floors. Impact noise between floors is the single biggest residential 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 / What it is
The product, described honestly, for a South Korea brief
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 apartment towers with underfloor heating and hard floors. Impact noise between floors is the single biggest residential complaint.
Work reaching us from South Korea is mostly apartment towers, manufacturing plants, offices, hotels, schools, studios.
- Noise between floors is the issue Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
- Concrete towers throughout The structure carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- Precise expectations Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- 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 South Korea.
02 / The build-up
The build-up, layer by layer
-
Layer 1
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 South Korea, central plant and split units, with risers and duct runs carrying noise between floors.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
-
Layer 2
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In South Korea, church buildings, halls and auditoria are large hard volumes carrying amplified speech and music.
Track with a seal. Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In South Korea, school and academy buildings are hard surfaced with long corridors and very intensive use.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
What decides the build-up in South Korea
- Noise between floors is the issue
Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
- Concrete towers throughout
The structure carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- Precise expectations
Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- Two strong ports
Busan and Incheon are both well served from India, so we route to whichever suits the site.
- The housing stock
Reinforced concrete apartment towers with underfloor heating and hard floors. Impact noise between floors is the single biggest residential complaint.
04 / Room by room
What each space in a South Korea project needs
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
- 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 carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- 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. Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- 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
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate
Durability in South Korea, before acoustics is discussed
South Korea 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 South Korea job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
The six errors that cost the most
-
Foam on the walls as a soundproofing measure
This is the one that comes back as a second fit-out rather than a snag.
-
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
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic South Korea job
Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
05 / Logistics
Supply into South Korea, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Busan or Incheon, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Busan |
| 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.

Questions from South Korea projects
What makes home theatre soundproofing and acoustics different in South Korea?
Reinforced concrete apartment towers with underfloor heating and hard floors. Impact noise between floors is the single biggest residential complaint. Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
Where should the budget go first on a South Korea 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 South Korea?
No. We manufacture in India and supply into South Korea. 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 South Korea site?
ships from: Palwal, Haryana, India, arrives at: Busan or Incheon, 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.
Next step
Send a plan and a section, get a real build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
