Home theatre soundproofing and acoustics in Dhaka
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. Reinforced concrete frames with brick infill and hard floors. Apartment blocks sit close together with shared walls and open light wells between them.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.

01 / What it is
The product, described honestly, for a Dhaka brief
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
Reinforced concrete frames with brick infill and hard floors. Apartment blocks sit close together with shared walls and open light wells between them.
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 Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in Dhaka.
02 / The build-up
What goes where, from the structure in
-
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.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
Layer 2
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Dhaka, community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
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.
- The housing stock
Reinforced concrete frames with brick infill and hard floors. Apartment blocks sit close together with shared walls and open light wells between them.

Where the money goes on a Dhaka project
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. 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.

- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. Standby generation sits in courtyards and alleys next to bedrooms and offices. Enclosure at the source is the only thing that works.

Reflections
Side wall and ceiling first reflection points at the seating position. There is often no gap at all between structures, so sound moves between buildings as well as within them.

For a Dhaka interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Conditions
Why the climate in Dhaka changes the material, not the target
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.
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.

Where this kind of project usually fails
-
Foam on the walls as a soundproofing measure
Small on the drawing, expensive on site, and almost always found after handover.
-
A standard door on a room built to hold bass
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating before the room is sealed
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.
-
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 / Route to site
Supply into Dhaka, start to 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 home theatre soundproofing and acoustics different in Dhaka?
Reinforced concrete frames with brick infill and hard floors. Apartment blocks sit close together with shared walls and open light wells between them. 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. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
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?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
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
Drawings in, BOQ and a delivered date out
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
