Hospital and healthcare acoustics in Dhaka
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 Dhaka
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 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.
- 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 Dhaka.
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 Dhaka, 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 Dhaka, community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
-
Layer 3
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Dhaka, classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
We would rather argue about the build-up at design stage than on site. 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.
- Plant and HVAC
Split units and diesel generator sets, with generators close to occupied rooms and running often.

Space by space, for Dhaka briefs
-
Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. 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.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Acoustic carpet and rugs, 4 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. Standby generation sits in courtyards and alleys next to bedrooms and offices. Enclosure at the source is the only thing that works.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Acoustic carpet and rugs, High density polyester
- Acoustic panels, ASTM C423
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. There is often no gap at all between structures, so sound moves between buildings as well as within them.
- PET felt acoustic panels, 4 to 24 mm
- Acoustic carpet and rugs, Felt
- 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 / Climate
What the Dhaka climate rules in and rules out
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.
06 / Before you buy
What we watch go wrong on jobs like this
-
Fabric wrapped products in a clinical area
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Absorption used where privacy was the requirement
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Ceiling void left open above a partition
A treated wall under a bare hard ceiling gives you a fraction of the reduction you paid for, and the room still sounds wrong.
-
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
Getting it to Dhaka, with real dates
| 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 hospital and healthcare acoustics different in Dhaka?
Split units and diesel generator sets, with generators close to occupied rooms and running often. 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?
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 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?
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.
