Auditorium acoustics and soundproofing in Thailand
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. Temples, function halls and hotel ballrooms are tall 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 this material is and where it earns its place in Thailand
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.
Temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music.
Work reaching us from Thailand is mostly industrial estates and plant, resorts and hotels, offices, hospitals, schools, studios.
- Two different markets Industrial estate work is enclosure and mass. Resort work is guest room isolation and function room acoustics. We quote them differently because they are different problems.
- Heat and humidity all year PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag in a tropical climate.
- Cooling plant never stops Large continuous cooling loads next to occupied space generate more complaints than anything happening inside the room.
- 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 Thailand.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Thailand, split units and VRF with condensers on balconies and in light wells, running at full load most of the year.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Thailand, temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Thailand, classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
Architects working in Thailand 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 we see driving Thailand briefs
- Two different markets
Industrial estate work is enclosure and mass. Resort work is guest room isolation and function room acoustics. We quote them differently because they are different problems.
- Heat and humidity all year
PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag in a tropical climate.
- Cooling plant never stops
Large continuous cooling loads next to occupied space generate more complaints than anything happening inside the room.
- Resort programmes have fixed dates
Openings do not move. We give honest dispatch and transit windows rather than optimistic ones.
- Assembly and performance rooms
Temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
04 / Room by room
Space by space, for Thailand briefs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Industrial estate work is enclosure and mass. Resort work is guest room isolation and function room acoustics. We quote them differently because they are different problems.
- Wood wool acoustic panels, 1200 x 600 mm
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag in a tropical climate.
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Large continuous cooling loads next to occupied space generate more complaints than anything happening inside the room.
- Wood wool acoustic panels, 400 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic carpet and rugs, 64 sq ft per pack
For a Thailand interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
Durability in Thailand, before acoustics is discussed
Thailand is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
Where a consultant is already engaged on a Thailand project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
Absorbing the whole room and losing the back rows
Small on the drawing, expensive on site, and almost always found after handover.
-
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 Thailand job
Industrial estate work is enclosure and mass. Resort work is guest room isolation and function room acoustics. We quote them differently because they are different problems.
05 / Logistics
Supply into Thailand, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Laem Chabang, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Laem Chabang |
| 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 Laem Chabang, then road to site. Air freight for samples and urgent quantities.
Questions from Thailand projects
What makes auditorium acoustics and soundproofing different in Thailand?
Temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music. Industrial estate work is enclosure and mass. Resort work is guest room isolation and function room acoustics. We quote them differently because they are different problems.
Where should the budget go first on a Thailand 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 Thailand?
No. We manufacture in India and supply into Thailand. 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 Thailand site?
ships from: Palwal, Haryana, India, arrives at: Laem Chabang, 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.
