Recording studio acoustics and soundproofing in Sweden
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 very deep music production culture where absorption data and measured targets are expected.
- 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.

01 / What it is
The material, and what it actually does on a Sweden job
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 very deep music production culture where absorption data and measured targets are expected.
Work reaching us from Sweden is mostly timber buildings and apartments, offices, schools, healthcare, hotels, studios.
- Timber at scale Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work.
- Classes are written and verified Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it.
- Sealed through a long winter Ventilation runs constantly in closed buildings, so plant noise matters more than street noise.
- 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 Sweden.
02 / The build-up
The build-up, layer by layer
-
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 Sweden, balanced mechanical ventilation with heat recovery running through long heating seasons, so duct noise is constant.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
-
Layer 2
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Sweden, church buildings, culture houses and school halls are hard long-decay volumes.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Sweden, classroom acoustics are regulated, and open plan learning areas make speech intelligibility the design target.
Double layer at a doorway. Two curtains with an air gap where a single layer will not reach the target.
If you are specifying for a Sweden project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What the buildings in Sweden do to the specification
- Timber at scale
Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work.
- Classes are written and verified
Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it.
- Sealed through a long winter
Ventilation runs constantly in closed buildings, so plant noise matters more than street noise.
- A long country
A site in the north has a real domestic leg. We quote it separately so the dates are honest.
- The housing stock
Concrete apartment blocks and timber frame housing with tight envelopes, hard floors and cold external walls.
- The studio and content scene
A very deep music production culture where absorption data and measured targets are expected.
04 / Room by room
What each space in a Sweden project needs
-
Isolation
A measured background level, agreed before anything is bought. Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work.
- Acoustic foam and BassBloc, 1800 x 900 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
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it.
- Acoustic foam and BassBloc, 20 mm
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic panels, ASTM C423
-
Early reflections
Controlled at the mix position, and only there. Ventilation runs constantly in closed buildings, so plant noise matters more than street noise.
- Acoustic foam and BassBloc, 100 kg per cubic metre
- 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 / Conditions
Durability in Sweden, before acoustics is discussed
Sweden is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The failure we design against here is condensation behind linings in older, poorly insulated stock.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Straight talk
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Sweden job
Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work.
05 / Logistics
Supply into Sweden, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Gothenburg, then road onward to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Gothenburg |
| 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 Gothenburg, then road onward to site. Air freight for samples and urgent quantities.
Questions from Sweden projects
What makes recording studio acoustics and soundproofing different in Sweden?
A very deep music production culture where absorption data and measured targets are expected. Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it.
Where should the budget go first on a Sweden 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 Sweden?
No. We manufacture in India and supply into Sweden. 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 Sweden site?
ships from: Palwal, Haryana, India, arrives at: Gothenburg, then road onward 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?
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
Tell us the room, we will tell you the build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
