Auditorium acoustics and soundproofing in Denmark
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem. Church buildings, civic halls and school halls are hard volumes with long decay carrying speech and music.
- Reverberation time
- Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
- Early reflections
- Shaped surfaces that send energy to the rear seats rather than absorbing everything.
- Rear wall
- The single worst surface in most halls, and the first one to treat.

01 / The material
What this is, and what it changes in a Denmark room
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem.
Church buildings, civic halls and school halls are hard volumes with long decay carrying speech and music.
Work reaching us from Denmark is mostly apartments, offices, schools, healthcare, timber buildings, studios.
- Classes are written and verified Work here arrives with a target and gets checked afterwards. Send us the class and we will say plainly what our material reaches and where it does not.
- Design led interiors Finish matters as much as performance. Colour consistency across a full order is part of the job, not an afterthought.
- Timber and lightweight construction Light structures pass low frequency easily, so mass and decoupling do the work rather than more absorption.
- Reverberation time Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for auditorium acoustics are on the main product page. This page covers what that means for a project in Denmark.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Denmark, balanced mechanical ventilation with heat recovery is standard, so duct and terminal noise replace open window noise.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Denmark, church buildings, civic halls and school halls are hard volumes with long decay carrying speech and music.
Slats on a cavity. Backing plus an air gap behind moves absorption lower, which matters in music rooms.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Denmark, classroom acoustics are taken seriously, and open plan learning spaces make speech intelligibility the design target rather than echo.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
If you are specifying for a Denmark project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.

What we see driving Denmark briefs
- Classes are written and verified
Work here arrives with a target and gets checked afterwards. Send us the class and we will say plainly what our material reaches and where it does not.
- Design led interiors
Finish matters as much as performance. Colour consistency across a full order is part of the job, not an afterthought.
- Timber and lightweight construction
Light structures pass low frequency easily, so mass and decoupling do the work rather than more absorption.
- Sealed through a long winter
Buildings close up with ventilation running constantly, so plant noise matters more than street noise.
- Assembly and performance rooms
Church buildings, civic halls and school halls are hard volumes with long decay carrying speech and music.
- School and campus buildings
Classroom acoustics are taken seriously, and open plan learning spaces make speech intelligibility the design target rather than echo.

Where the money goes on a Denmark project
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Work here arrives with a target and gets checked afterwards. Send us the class and we will say plainly what our material reaches and where it does not.
- Wooden slat acoustic panels, MDF, FR MDF, HDF or HDHMR
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Finish matters as much as performance. Colour consistency across a full order is part of the job, not an afterthought.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- PET felt acoustic panels, 4 to 24 mm
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Light structures pass low frequency easily, so mass and decoupling do the work rather than more absorption.
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Acoustic carpet and rugs, 64 sq ft per pack
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
Durability in Denmark, before acoustics is discussed
Denmark 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 / Before you buy
Six mistakes that turn into a second fit-out
-
Absorbing the whole room and losing the back rows
This is the one that comes back as a second fit-out rather than a snag.
-
Adding speakers to fix a reverberation problem
This is the one that comes back as a second fit-out rather than a snag.
-
Ignoring the rear wall because it is behind the audience
It sounds like a small detail until the room is finished and the complaint arrives.

Treating it as a generic Denmark job
Work here arrives with a target and gets checked afterwards. Send us the class and we will say plainly what our material reaches and where it does not.

Questions from Denmark projects
What makes auditorium acoustics and soundproofing different in Denmark?
Church buildings, civic halls and school halls are hard volumes with long decay carrying speech and music. Work here arrives with a target and gets checked afterwards. Send us the class and we will say plainly what our material reaches and where it does not.
Where should the budget go first on a Denmark project?
Reverberation time. Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Early reflections. Shaped surfaces that send energy to the rear seats rather than absorbing everything.
Do you have an office or installation team in Denmark?
No. We manufacture in India and supply into Denmark. 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 Denmark site?
ships from: Palwal, Haryana, India, arrives at: Aarhus or Copenhagen, then a short road run to site, 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?
Absorbing the whole room and losing the back rows. Adding speakers to fix a reverberation problem.
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.

Tell us the room, we will tell you the build-up
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
