Hospital and healthcare acoustics in Kolkata
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, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
- 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 this material is and where it earns its place in Kolkata
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, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
Work reaching us from Kolkata is mostly old buildings and conversions, offices, clubs and restaurants, schools, clinics, auditoriums.
- Tall rooms, hard plaster High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
- Timber floors between floors Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- The structure is staying Conversions here keep the original fabric, so the work has to be internal, shallow and ideally reversible.
- Consulting room privacy Speech privacy between rooms, which is partition, door and ceiling void work.

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 Kolkata.
02 / The build-up
What goes where, from the structure in
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Kolkata, split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Kolkata, auditoria, community halls and pandal spaces carry amplified speech and music at high level.
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 3
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 Kolkata, long established schools and colleges in masonry with high ceilings and very large class sizes.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
For a Kolkata practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / In this market
What we see driving Kolkata briefs
- Tall rooms, hard plaster
High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
- Timber floors between floors
Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- The structure is staying
Conversions here keep the original fabric, so the work has to be internal, shallow and ideally reversible.
- Humid most of the year
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Plant and HVAC
Split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.

Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- 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. Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic panels, ASTM C423
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Conversions here keep the original fabric, so the work has to be internal, shallow and ideally reversible.
- PET felt acoustic panels, 4 to 24 mm
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
- 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 / Durability
Why the climate in Kolkata changes the material, not the target
Kolkata 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 / Straight talk
The six errors that cost the most
-
Fabric wrapped products in a clinical area
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Absorption used where privacy was the requirement
If the complaint is being overheard, no amount of absorption inside the room will fix it. That is a partition job and we will say so.
-
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 Kolkata job
High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
05 / Logistics
What the route into Kolkata actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three days |
| Dispatch | 2 to 4 working days |
| To site | three days |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly fourteen hundred kilometres, normally three days on a dedicated truck.
Questions from Kolkata projects
What makes hospital and healthcare acoustics different in Kolkata?
Split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs. High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
Where should the budget go first on a Kolkata 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 Kolkata?
No. We manufacture in India and supply into Kolkata. 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 Kolkata site?
made at: Our own plant, Palwal, Haryana, reaches site in: three days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. 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.
