Venue and restaurant acoustics in Johannesburg
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other. Church buildings and community halls are large hard rooms carrying amplified music and speech at high level.
- Containment
- Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
- Table level comfort
- Absorption at the ceiling so guests stop raising their voices at each other.
- Entrance and service
- Doors, lobbies and extract paths, which is where most of the leakage actually is.

The material, and what it actually does on a Johannesburg job
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other.
Church buildings and community halls are large hard rooms carrying amplified music and speech at high level.
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.
- Containment Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for venue soundproofing 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
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Johannesburg, split units and generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Johannesburg, church buildings and community halls are large hard rooms carrying amplified music and speech at high level.
Slats on felt backing. The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Johannesburg, classrooms are hard walled with high ceilings and large class sizes, and school halls double as assembly and performance spaces.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
For a Johannesburg practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / Local conditions
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.
- Assembly and performance rooms
Church buildings and community halls are large hard rooms carrying amplified music and speech at high level.

Where the money goes on a Johannesburg project
-
Containment
Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. 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 panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Acoustic carpet and rugs, High density polyester
-
Table level comfort
Absorption at the ceiling so guests stop raising their voices at each other. 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 panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Acoustic carpet and rugs, Felt
-
Entrance and service
Doors, lobbies and extract paths, which is where most of the leakage actually is. The inland leg is long and it is real. We quote it separately so the programme is built on actual dates.
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Wooden slat acoustic panels, 14, 16 and 18 mm
- Acoustic carpet and rugs, 64 sq ft per pack
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 and durability
Durability in Johannesburg, before acoustics is discussed
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.
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.

The six errors that cost the most
-
Panels on the wall as a neighbour noise solution
Small on the drawing, expensive on site, and almost always found after handover.
-
A lobby with both doors able to open at once
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Extract ducting that bypasses every wall you built
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.

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 / Logistics
Getting it to Johannesburg, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Durban, then road up to Johannesburg |
| 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 venue and restaurant acoustics different in Johannesburg?
Church buildings and community halls are large hard rooms carrying amplified music and speech at high level. 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?
Containment. Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Table level comfort. Absorption at the ceiling so guests stop raising their voices at each other.
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?
Panels on the wall as a neighbour noise solution. A lobby with both doors able to open at once.
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.
