Venue and restaurant acoustics in Dhaka
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other. Community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
- Containment
- Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
- Table level comfort
- Absorption at the ceiling so guests stop raising their voices at each other.
- Entrance and service
- Doors, lobbies and extract paths, which is where most of the leakage actually is.

01 / The product
What this is, and what it changes in a Dhaka room
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other.
Community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Work reaching us from Dhaka is mostly apartments, offices, garment unit admin blocks, hospitals, schools, hotels, studios.
- Noise arrives from outside Traffic, generators and construction reach the room through windows and gaps long before they come through the wall. Treat the weakest path, not the biggest surface.
- Generators in every gap Standby generation sits in courtyards and alleys next to bedrooms and offices. Enclosure at the source is the only thing that works.
- Buildings against buildings There is often no gap at all between structures, so sound moves between buildings as well as within them.
- Containment Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for venue soundproofing are on the main product page. This page covers what that means for a project in Dhaka.

02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Dhaka, split units and diesel generator sets, with generators close to occupied rooms and running often.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 2
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Dhaka, community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Dhaka, classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
If you are specifying for a Dhaka 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 the buildings in Dhaka do to the specification
- Noise arrives from outside
Traffic, generators and construction reach the room through windows and gaps long before they come through the wall. Treat the weakest path, not the biggest surface.
- Generators in every gap
Standby generation sits in courtyards and alleys next to bedrooms and offices. Enclosure at the source is the only thing that works.
- Buildings against buildings
There is often no gap at all between structures, so sound moves between buildings as well as within them.
- A short route from the plant
Sea into Chattogram or overland through the border, which keeps lead times short and consignments flexible.
- Assembly and performance rooms
Community halls, places of worship and conference rooms are hard volumes carrying amplified speech.

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 / Climate and durability
Durability in Dhaka, before acoustics is discussed
Dhaka 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.
On a Dhaka job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Six mistakes that turn into a second fit-out
-
Panels on the wall as a neighbour noise solution
Small on the drawing, expensive on site, and almost always found after handover.
-
A lobby with both doors able to open at once
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Extract ducting that bypasses every wall you built
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Treating it as a generic Dhaka job
Traffic, generators and construction reach the room through windows and gaps long before they come through the wall. Treat the weakest path, not the biggest surface.
05 / Supply
How material reaches a Dhaka site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Chattogram or the land border, then road into Dhaka |
| Dispatch | 4 to 7 working days |
| Freight | Sea or land border |
| 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 Chattogram or overland through the land border, then road into Dhaka. Air freight for samples and urgent quantities.
Questions from Dhaka projects
What makes venue and restaurant acoustics different in Dhaka?
Community halls, places of worship and conference rooms are hard volumes carrying amplified speech. Traffic, generators and construction reach the room through windows and gaps long before they come through the wall. Treat the weakest path, not the biggest surface.
Where should the budget go first on a Dhaka project?
Containment. Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Table level comfort. Absorption at the ceiling so guests stop raising their voices at each other.
Do you have an office or installation team in Dhaka?
No. We manufacture in India and supply into Dhaka. 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 Dhaka site?
ships from: Palwal, Haryana, India, arrives at: Chattogram or the land border, then road into Dhaka, 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?
Panels on the wall as a neighbour noise solution. A lobby with both doors able to open at once.
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.
