Hospital and healthcare acoustics in Brazil
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 VRF, with condensers in light wells and on facades close to bedrooms.
- 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 Brazil
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 VRF, with condensers in light wells and on facades close to bedrooms.
Work reaching us from Brazil is mostly offices and corporate towers, apartments, hotels, schools, hospitals, studios.
- Concrete and block, hard inside The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
- Impact through slabs Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix.
- A long sea leg and a real import process Transit is long and customs takes time. We quote the full window and give you the documentation package up front rather than after the container sails.
- 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 Brazil.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Brazil, split units and VRF, with condensers in light wells and on facades close to bedrooms.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 2
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Brazil, churches, event halls and auditoriums are large hard rooms carrying amplified 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 Brazil, classrooms are concrete and tile with high ceilings and hard floors, and covered play areas amplify everything.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
Architects working in Brazil 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 / In this market
What the buildings in Brazil do to the specification
- Concrete and block, hard inside
The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
- Impact through slabs
Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix.
- A long sea leg and a real import process
Transit is long and customs takes time. We quote the full window and give you the documentation package up front rather than after the container sails.
- Humid in most of the country
PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a few seasons.
- Plant and HVAC
Split units and VRF, with condensers in light wells and on facades close to bedrooms.
04 / Room by room
Space by space, for Brazil briefs
-
Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
- 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. Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix.
- 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. Transit is long and customs takes time. We quote the full window and give you the documentation package up front rather than after the container sails.
- 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 / Climate
Why the climate in Brazil changes the material, not the target
Brazil 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
Where this kind of project usually fails
-
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
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
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
Treating it as a generic Brazil job
The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
05 / Logistics
How material reaches a Brazil site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Santos or Paranaguá, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Santos |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Santos or Paranaguá, then road to site. Air freight for samples and urgent quantities.
Questions from Brazil projects
What makes hospital and healthcare acoustics different in Brazil?
Split units and VRF, with condensers in light wells and on facades close to bedrooms. The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
Where should the budget go first on a Brazil 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 Brazil?
No. We manufacture in India and supply into Brazil. 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 Brazil site?
ships from: Palwal, Haryana, India, arrives at: Santos or Paranaguá, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
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.
