Auditorium acoustics and soundproofing in Bangkok
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 you are buying, and what it fixes in Bangkok
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 Bangkok is mostly condo towers, hotels and lounges, offices, restaurants, clinics, studios.
- Concrete towers, live interiors The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Elevated rail and traffic Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- Impact through slabs Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- 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 Bangkok.
02 / The build-up
What goes where, from the structure in
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bangkok, split units and VRF with condensers on balconies and in light wells, running at full load most of the year.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bangkok, temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Bangkok, classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
For a Bangkok practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / On the ground
What decides the build-up in Bangkok
- Concrete towers, live interiors
The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Elevated rail and traffic
Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- Impact through slabs
Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- Heat and humidity all year
Our PET felt does not hold moisture or feed mould, which matters where mineral products sag in a tropical climate.
- 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.

What each space in a Bangkok project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- PET felt acoustic panels, 4 to 24 mm
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- Wood wool acoustic panels, 20 mm
- 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
-
Rear wall
The single worst surface in most halls, and the first one to treat. Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
For a Bangkok 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 Bangkok, before acoustics is discussed
Bangkok 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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.

The six errors that cost the most
-
Absorbing the whole room and losing the back rows
This is the one that comes back as a second fit-out rather than a snag.
-
Adding speakers to fix a reverberation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
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 Bangkok job
The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
05 / Supply

Questions from Bangkok projects
What makes auditorium acoustics and soundproofing different in Bangkok?
Temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music. The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
Where should the budget go first on a Bangkok 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 Bangkok?
No. We manufacture in India and supply into Bangkok. 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 Bangkok site?
ships from: Palwal, Haryana, India, arrives at: Laem Chabang, then a short road run into Bangkok, 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.
