Auditorium acoustics and soundproofing in Austria
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. Concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
- 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 you are buying, and what it fixes in Austria
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.
Concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
Work reaching us from Austria is mostly apartments, alpine hotels, offices, schools, clinics, studios, timber buildings.
- Landlocked, so plan the inland leg Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
- Timber construction is growing Cross laminated and timber frame buildings are light. Light means low frequency passes easily, so the answer is added mass and a resilient break, not more absorption.
- Resort work runs to an opening date Alpine hotel refurbishment happens in a short window between seasons. Real dispatch and transit dates matter more than a slightly better price.
- 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 Austria.
02 / The build-up
The build-up, layer by layer
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Austria, mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Austria, concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Austria, school and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
Architects working in Austria 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 / Local conditions
The Austria conditions that change the answer
- Landlocked, so plan the inland leg
Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
- Timber construction is growing
Cross laminated and timber frame buildings are light. Light means low frequency passes easily, so the answer is added mass and a resilient break, not more absorption.
- Resort work runs to an opening date
Alpine hotel refurbishment happens in a short window between seasons. Real dispatch and transit dates matter more than a slightly better price.
- Numbers before materials
Send the target values and the build-up. We will tell you what our material reaches and where it will not get you there, in writing, before you commit.
- Assembly and performance rooms
Concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
- School and campus buildings
School and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
04 / Room by room
What each space in a Austria project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Cross laminated and timber frame buildings are light. Light means low frequency passes easily, so the answer is added mass and a resilient break, not more absorption.
- Wood wool acoustic panels, 20 mm
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
Rear wall
The single worst surface in most halls, and the first one to treat. Alpine hotel refurbishment happens in a short window between seasons. Real dispatch and transit dates matter more than a slightly better price.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- Ceiling baffles and clouds, ASTM C423
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Durability
The Austria climate decides the material list
Austria 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
What we watch go wrong on jobs like this
-
Absorbing the whole room and losing the back rows
It sounds like a small detail until the room is finished and the complaint arrives.
-
Adding speakers to fix a reverberation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
Ignoring the rear wall because it is behind the audience
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Austria job
Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
05 / Route to site
How material reaches a Austria site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Koper or Hamburg, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Koper or Hamburg |
| 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 Koper or Hamburg, then rail and road inland. Air freight for samples and urgent quantities.
Questions from Austria projects
What makes auditorium acoustics and soundproofing different in Austria?
Concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible. Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
Where should the budget go first on a Austria 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 Austria?
No. We manufacture in India and supply into Austria. 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 Austria site?
ships from: Palwal, Haryana, India, arrives at: Koper or Hamburg, then rail and road inland, 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.
Next step
Tell us the room, we will tell you the build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
