Auditorium acoustics and soundproofing in Ho Chi Minh City
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. Function halls, places of worship and conference rooms are 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 product
What this material is and where it earns its place in Ho Chi Minh City
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.
Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
Work reaching us from Ho Chi Minh City is mostly tube houses and apartments, towers and offices, manufacturing, hotels, schools, clinics.
- Narrow, deep, shared on both sides The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
- Traffic never stops Constant street noise gets in through openings and glazing. The facade is where the first money should go, not the wall.
- New towers, hard interiors Concrete frames with tile and glass inside. The structure blocks, the room rings.
- 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 Ho Chi Minh City.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Ho Chi Minh City, split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
Slats on felt backing. The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Ho Chi Minh City, function halls, places of worship and conference rooms are 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 Ho Chi Minh City, classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
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 Ho Chi Minh City 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 / Local conditions
What decides the build-up in Ho Chi Minh City
- Narrow, deep, shared on both sides
The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
- Traffic never stops
Constant street noise gets in through openings and glazing. The facade is where the first money should go, not the wall.
- New towers, hard interiors
Concrete frames with tile and glass inside. The structure blocks, the room rings.
- Tropical humidity all year
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Assembly and performance rooms
Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are hard, naturally ventilated and open to street noise, with large class sizes.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
- Wood wool acoustic panels, 1200 x 600 mm
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Constant street noise gets in through openings and glazing. The facade is where the first money should go, not the wall.
- Wood wool acoustic panels, 20 mm
- PET felt acoustic panels, 4 to 24 mm
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Concrete frames with tile and glass inside. The structure blocks, the room rings.
- Wood wool acoustic panels, 400 kg per cubic metre
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Acoustic carpet and rugs, 64 sq ft per pack
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 Ho Chi Minh City, before acoustics is discussed
Ho Chi Minh City 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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Straight talk
Six mistakes that turn into a second fit-out
-
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
Small on the drawing, expensive on site, and almost always found after handover.
-
Ignoring the rear wall because it is behind the audience

Treating it as a generic Ho Chi Minh City job
The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
05 / Logistics
Getting it to Ho Chi Minh City, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Cat Lai or Cai Mep, then a short road run into the city |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Cat Lai or Cai Mep |
| 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 Cat Lai or Cai Mep, then a short road run into the city. Air freight for samples and urgent quantities.
Questions from Ho Chi Minh City projects
What makes auditorium acoustics and soundproofing different in Ho Chi Minh City?
Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music. The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
Where should the budget go first on a Ho Chi Minh City 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 Ho Chi Minh City?
No. We manufacture in India and supply into Ho Chi Minh City. 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 Ho Chi Minh City site?
ships from: Palwal, Haryana, India, arrives at: Cat Lai or Cai Mep, then a short road run into the city, 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.
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.
