Hospital and healthcare acoustics in Johannesburg
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 generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC.
- 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 / What it is
The product, described honestly, for a Johannesburg brief
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 generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC.
Work reaching us from Johannesburg is mostly corporate office parks, generator enclosures, retail, hotels, schools, hospitals, studios.
- Generator noise is routine Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer.
- Office parks, not street frontage Campus style buildings with large open floors and hard finishes. Speech carries a long way and the ceiling plane has to carry the room.
- The climb from Durban The inland leg is long and it is real. We quote it separately so the programme is built on actual dates.
- 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 Johannesburg.
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 Johannesburg, split units and generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Johannesburg, church buildings and community halls are large hard rooms carrying amplified music and speech at high level.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 3
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Johannesburg, classrooms are hard walled with high ceilings and large class sizes, and school halls double as assembly and performance spaces.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
Architects working in Johannesburg 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 / What drives the brief
The Johannesburg conditions that change the answer
- Generator noise is routine
Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer.
- Office parks, not street frontage
Campus style buildings with large open floors and hard finishes. Speech carries a long way and the ceiling plane has to carry the room.
- The climb from Durban
The inland leg is long and it is real. We quote it separately so the programme is built on actual dates.
- Altitude and dry air
PET felt is stable in dry conditions and does not shed fibre, which suits sealed, conditioned buildings.
- Plant and HVAC
Split units and generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC.

Where the money goes on a Johannesburg project
-
Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer.
- Acoustic carpet and rugs, 500 x 500 mm
- 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. Campus style buildings with large open floors and hard finishes. Speech carries a long way and the ceiling plane has to carry the room.
- Acoustic carpet and rugs, 4 mm
- 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. The inland leg is long and it is real. We quote it separately so the programme is built on actual dates.
- Acoustic carpet and rugs, High density polyester
- 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
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate and durability
What the Johannesburg climate rules in and rules out
Johannesburg is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
Where a consultant is already engaged on a Johannesburg project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
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
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 Johannesburg job
Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer.
05 / Route to site
Supply into Johannesburg, start to site
| Ships from | Palwal, Haryana, India |
|---|---|

| Dispatch | 4 to 7 working days |
| Freight | Sea via Durban |
| 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 Durban, then road up to Johannesburg. Air freight for samples and urgent quantities.
Questions from Johannesburg projects
What makes hospital and healthcare acoustics different in Johannesburg?
Split units and generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC. Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer.
Where should the budget go first on a Johannesburg 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 Johannesburg?
No. We manufacture in India and supply into Johannesburg. 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 Johannesburg site?
ships from: Palwal, Haryana, India, arrives at: Durban, then road up to Johannesburg, 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.
