Auditorium acoustics and soundproofing in South Korea
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 auditoria are large hard volumes carrying amplified speech and music.
- 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 South Korea
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 auditoria are large hard volumes carrying amplified speech and music.
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.
- 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 South Korea.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In South Korea, central plant and split units, with risers and duct runs carrying noise between floors.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In South Korea, church buildings, halls and auditoria are large hard volumes carrying amplified speech and music.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In South Korea, school and academy buildings are hard surfaced with long corridors and very intensive use.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
If you are specifying for a South Korea project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What we see driving South Korea briefs
- 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.
- Assembly and performance rooms
Church buildings, halls and auditoria are large hard volumes carrying amplified speech and music.
- School and campus buildings
School and academy buildings are hard surfaced with long corridors and very intensive use.
04 / Room by room
Where the money goes on a South Korea project
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. 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.
- Wooden slat acoustic panels, MDF, FR MDF, HDF or HDHMR
- 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
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. The structure carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- 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
-
Rear wall
The single worst surface in most halls, and the first one to treat. Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Ceiling baffles and clouds, ASTM C423
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
The South Korea climate decides the material list
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 / Before you buy
What we watch go wrong on jobs like this
-
Absorbing the whole room and losing the back rows
It sounds like a small detail until the room is finished and the complaint arrives.
-
Adding speakers to fix a reverberation problem
This is the one that comes back as a second fit-out rather than a snag.
-
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 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 / Getting it there
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.
Sea freight into Busan or Incheon, then road to site. Air freight for samples and urgent quantities.
Questions from South Korea projects
What makes auditorium acoustics and soundproofing different in South Korea?
Church buildings, halls and auditoria are large hard volumes carrying amplified speech and music. 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?
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 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?
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.
