Recording studio acoustics and soundproofing in Norway
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 recording culture with rooms built to measured targets inside timber and concrete structures.
- 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 / The material
What this is, and what it changes in a Norway room
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 recording culture with rooms built to measured targets inside timber and concrete structures.
Work reaching us from Norway is mostly timber buildings and apartments, offices, schools, healthcare, hotels, studios.
- Timber is light Timber construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
- Classes are written and checked Work arrives with a target and someone verifies it. Send us the class and we will say plainly where our material sits.
- Sealed through a long winter Ventilation runs constantly in closed buildings, so plant noise matters far 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 Norway.
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 Norway, balanced mechanical ventilation with heat recovery runs constantly through long heating seasons, so duct noise is always present.
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
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Norway, church buildings, culture houses and school halls are hard volumes carrying speech and music.
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
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 Norway, classroom acoustics are regulated and taken seriously, with open plan learning spaces making intelligibility the target.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
For a Norway practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / On the ground
What the buildings in Norway do to the specification
- Timber is light
Timber construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
- Classes are written and checked
Work arrives with a target and someone verifies it. Send us the class and we will say plainly where our material sits.
- Sealed through a long winter
Ventilation runs constantly in closed buildings, so plant noise matters far more than street noise.
- A long country
A site north of Oslo has a real domestic leg. We quote it separately so the programme is built on actual dates.
- The housing stock
Timber frame housing and concrete apartment blocks, both with very tight envelopes and hard internal finishes.
- The studio and content scene
A strong recording culture with rooms built to measured targets inside timber and concrete structures.
04 / Room by room
Room by room, on a typical Norway job
-
Isolation
A measured background level, agreed before anything is bought. Timber construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
- Acoustic foam and BassBloc, 1800 x 900 mm
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Soundproof curtains, 5.5 kg per sq m
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Work arrives with a target and someone verifies it. Send us the class and we will say plainly where our material sits.
- Acoustic foam and BassBloc, 20 mm
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Soundproof curtains, Up to 30 dB
-
Early reflections
Controlled at the mix position, and only there. Ventilation runs constantly in closed buildings, so plant noise matters far more than street noise.
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Soundproof curtains, 30
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
What the Norway climate rules in and rules out
Norway 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 / Read this first
Six mistakes that turn into a second fit-out
-
Buying foam to solve an isolation problem
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Norway job
Timber construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
05 / Route to site
What the route into Norway actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Oslo, then road onward to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Oslo |
| 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 Oslo, then road onward to site. Air freight for samples and urgent quantities.
Questions from Norway projects
What makes recording studio acoustics and soundproofing different in Norway?
A strong recording culture with rooms built to measured targets inside timber and concrete structures. Timber construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
Where should the budget go first on a Norway 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 Norway?
No. We manufacture in India and supply into Norway. 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 Norway site?
ships from: Palwal, Haryana, India, arrives at: Oslo, 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.
