Recording studio acoustics and soundproofing in Johannesburg
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later. A strong music and production culture works out of converted commercial and residential rooms with no isolation plan.
- Isolation
- A measured background level, agreed before anything is bought.
- Low frequency
- Corner and boundary absorption with real depth, not surface foam.
- Early reflections
- Controlled at the mix position, and only there.
- Quote
- From a plan and a section, within 48 hours
01 / The product
What you are buying, and what it fixes in Johannesburg
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later.
A strong music and production culture works out of converted commercial and residential rooms with no isolation plan.
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.
- Isolation A measured background level, agreed before anything is bought.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for studio soundproofing are on the main product page. This page covers what that means for a project in Johannesburg.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Acoustic foam and BassBloc
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing. In Johannesburg, split units and generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC.
First reflection points. Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
-
Layer 2
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 Johannesburg, church buildings and community halls are large hard rooms carrying amplified music and speech at high level.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Johannesburg, classrooms are hard walled with high ceilings and large class sizes, and school halls double as assembly and performance spaces.
Full height with return. Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
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 / In this market
What we see driving Johannesburg briefs
- 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.
- The housing stock
Brick and concrete construction with hard floors. Townhouse and cluster developments share walls that were built for structure, not for separation.
- The studio and content scene
A strong music and production culture works out of converted commercial and residential rooms with no isolation plan.

Space by space, for Johannesburg briefs
-
Isolation
A measured background level, agreed before anything is bought. Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Soundproof curtains, 5.5 kg per sq m
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Campus style buildings with large open floors and hard finishes. Speech carries a long way and the ceiling plane has to carry the room.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Soundproof curtains, Up to 30 dB
-
Early reflections
Controlled at the mix position, and only there. The inland leg is long and it is real. We quote it separately so the programme is built on actual dates.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic panels, ASTM C423
- Soundproof curtains, 30
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
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.
On a Johannesburg job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Where this kind of project usually fails
-
Buying foam to solve an isolation problem
This is the one that comes back as a second fit-out rather than a snag.
-
Treating the room before the shell is isolated
This is the one that comes back as a second fit-out rather than a snag.
-
Killing the room completely and calling it controlled
We would rather calculate the area and sell you less of it than line every surface and call it thorough.
-
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 / Supply
How material reaches a Johannesburg site
| 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 recording studio acoustics and soundproofing different in Johannesburg?
A strong music and production culture works out of converted commercial and residential rooms with no isolation plan. 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?
Isolation. A measured background level, agreed before anything is bought. Low frequency. Corner and boundary absorption with real depth, not surface foam.
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?
Buying foam to solve an isolation problem. Treating the room before the shell is isolated.
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
Send the drawings, get a straight answer
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.
