Auditorium acoustics and soundproofing in Czechia
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-decay volumes in stone and plaster.
- 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 material is and where it earns its place in Czechia
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-decay volumes in stone and plaster.
Work reaching us from Czechia is mostly production halls, plant rooms, offices, panel block apartments, schools, clinics.
- Panel block apartments Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
- Industrial noise is a mass problem Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you.
- Value is checked properly Czech buyers compare specifications line by line. That suits a manufacturer, because we can answer for what is actually in the product.
- 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 Czechia.
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 Czechia, mechanical ventilation in newer buildings and radiator heating in older stock, so duct noise is a newer problem than it looks.
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 Czechia, concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.
Slats on a cavity. Backing plus an air gap behind moves absorption lower, which matters in music rooms.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Czechia, school buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
Architects working in Czechia usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

What decides the build-up in Czechia
- Panel block apartments
Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
- Industrial noise is a mass problem
Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you.
- Value is checked properly
Czech buyers compare specifications line by line. That suits a manufacturer, because we can answer for what is actually in the product.
- Landlocked, so plan the inland leg
Hamburg then rail and road. We quote the sea leg and the inland leg separately so the programme is built on real dates.
- Assembly and performance rooms
Concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.
- School and campus buildings
School buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.

Where the money goes on a Czechia project
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- PET felt acoustic panels, 4 to 24 mm
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you.
- Wood wool acoustic panels, 20 mm
- 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
-
Rear wall
The single worst surface in most halls, and the first one to treat. Czech buyers compare specifications line by line. That suits a manufacturer, because we can answer for what is actually in the product.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
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 and durability
Durability in Czechia, before acoustics is discussed
Czechia 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.
Where a consultant is already engaged on a Czechia project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Before you buy
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
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Czechia job
Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
05 / Logistics
Supply into Czechia, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hamburg, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via 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.

Questions from Czechia projects
What makes auditorium acoustics and soundproofing different in Czechia?
Concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster. Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
Where should the budget go first on a Czechia 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 Czechia?
No. We manufacture in India and supply into Czechia. 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 Czechia site?
ships from: Palwal, Haryana, India, arrives at: 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.
