Auditorium acoustics and soundproofing in Vienna
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 / What it is
The product, described honestly, for a Vienna brief
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 Vienna is mostly gründerzeit apartments, offices, studios, restaurants, clinics, schools, hotels.
- Gründerzeit rooms are tall and hard High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
- Timber floors between apartments Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling underneath.
- Quiet hours are taken seriously Neighbour complaints here are not shrugged off. The isolation layer is what protects a home studio, a practice room or a late venue from becoming somebody else problem.
- 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 Vienna.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Vienna, mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Vienna, concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
Slats on felt backing. The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Vienna, school and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
For a Vienna practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / In this market
What the buildings in Vienna do to the specification
- Gründerzeit rooms are tall and hard
High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
- Timber floors between apartments
Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling underneath.
- Quiet hours are taken seriously
Neighbour complaints here are not shrugged off. The isolation layer is what protects a home studio, a practice room or a late venue from becoming somebody else problem.
- Trams and the Ring
Ground level trams and traffic put low frequency into the structure. Panels on a wall will not touch it, and we will say so rather than sell them.
- 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.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling underneath.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Neighbour complaints here are not shrugged off. The isolation layer is what protects a home studio, a practice room or a late venue from becoming somebody else problem.
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate
Why the climate in Vienna changes the material, not the target
Vienna 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
The six errors that cost the most
-
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 Vienna job
High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.

Questions from Vienna projects
What makes auditorium acoustics and soundproofing different in Vienna?
Concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible. High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
Where should the budget go first on a Vienna 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 Vienna?
No. We manufacture in India and supply into Vienna. 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 Vienna site?
ships from: Palwal, Haryana, India, arrives at: Koper or Hamburg, then rail and road into Vienna, 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.
