Recording studio acoustics and soundproofing in Bangladesh
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later. Studios go into apartment rooms and commercial floors with neighbours on every side and generators running during outages.
- Isolation
- A measured background level, agreed before anything is bought.
- Low frequency
- Corner and boundary absorption with real depth, not surface foam.
- Early reflections
- Controlled at the mix position, and only there.

01 / What it is
The product, described honestly, for a Bangladesh brief
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later.
Studios go into apartment rooms and commercial floors with neighbours on every side and generators running during outages.
Work reaching us from Bangladesh is mostly garment and manufacturing units, generator and plant rooms, offices, hospitals, schools, hotels.
- Reachable by road The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
- Garment units at scale Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- Generators run constantly Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- Isolation A measured background level, agreed before anything is bought.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for studio soundproofing are on the main product page. This page covers what that means for a project in Bangladesh.
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 Bangladesh, split units and diesel generator sets, with generators close to occupied rooms and running often.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 Bangladesh, community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Bangladesh, classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
Track with a seal. Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
For a Bangladesh practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / Local conditions
What the buildings in Bangladesh do to the specification
- Reachable by road
The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
- Garment units at scale
Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- Generators run constantly
Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- Dense, humid, monsoon climate
PET felt does not hold moisture or feed mould, which decides whether a ceiling survives more than a couple of seasons.
- 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.
- The studio and content scene
Studios go into apartment rooms and commercial floors with neighbours on every side and generators running during outages.

- Acoustic foam and BassBloc, 1800 x 900 mm
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.

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
Why the climate in Bangladesh changes the material, not the target
Bangladesh 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 Bangladesh project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

What we watch go wrong on jobs like this
-
Buying foam to solve an isolation problem
This is the one that comes back as a second fit-out rather than a snag.
-
Treating the room before the shell is isolated
This is the one that comes back as a second fit-out rather than a snag.
-
Killing the room completely and calling it controlled
A room can be over-treated. Past the target it stops sounding controlled and starts sounding dead, and you paid for that.
-
Treating it as a generic Bangladesh job
The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
05 / Logistics
Getting it to Bangladesh, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Chattogram by sea, or overland through the land border |
| 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 where that suits the programme better. Air freight for samples and urgent quantities.
Questions from Bangladesh projects
What makes recording studio acoustics and soundproofing different in Bangladesh?
Studios go into apartment rooms and commercial floors with neighbours on every side and generators running during outages. The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
Where should the budget go first on a Bangladesh project?
Isolation. A measured background level, agreed before anything is bought. Low frequency. Corner and boundary absorption with real depth, not surface foam.
Do you have an office or installation team in Bangladesh?
No. We manufacture in India and supply into Bangladesh. 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 Bangladesh site?
ships from: Palwal, Haryana, India, arrives at: Chattogram by sea, or overland through the land border, 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?
Buying foam to solve an isolation problem. Treating the room before the shell is isolated.
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.
