Hospital and healthcare acoustics in Bangladesh
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed. Split units and diesel generator sets, with generators close to occupied rooms and running often.
- Consulting room privacy
- Speech privacy between rooms, which is partition, door and ceiling void work.
- Ward noise floor
- Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
- Cleanability
- Non shedding, non absorbent surfaces that survive a cleaning regime.

01 / The material
What you are buying, and what it fixes in Bangladesh
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed.
Split units and diesel generator sets, with generators close to occupied rooms and running often.
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.
- Consulting room privacy Speech privacy between rooms, which is partition, door and ceiling void work.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for healthcare acoustics are on the main product page. This page covers what that means for a project in Bangladesh.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bangladesh, split units and diesel generator sets, with generators close to occupied rooms and running often.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Bangladesh, community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
-
Layer 3
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Bangladesh, classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
Architects working in Bangladesh 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
The Bangladesh conditions that change the answer
- 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.
- Plant and HVAC
Split units and diesel generator sets, with generators close to occupied rooms and running often.

Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. 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.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Ward noise floor
Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling. Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
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 / Conditions
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.
On a Bangladesh job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Straight talk
The six errors that cost the most
-
Fabric wrapped products in a clinical area
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Absorption used where privacy was the requirement
Privacy is a transmission problem. Absorption makes the room sound nicer and does not stop anyone hearing through the wall.
-
Ceiling void left open above a partition
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
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
What the route into Bangladesh actually looks like
| 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 hospital and healthcare acoustics different in Bangladesh?
Split units and diesel generator sets, with generators close to occupied rooms and running often. 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?
Consulting room privacy. Speech privacy between rooms, which is partition, door and ceiling void work. Ward noise floor. Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
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?
Fabric wrapped products in a clinical area. Absorption used where privacy was the requirement.
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.
