Auditorium acoustics and soundproofing in Frankfurt
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 Saal spaces are long-reverberation rooms where any intervention has to be reversible and visually disciplined.
- 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 product
What this is, and what it changes in a Frankfurt 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.
Concert halls, church buildings and civic Saal spaces are long-reverberation rooms where any intervention has to be reversible and visually disciplined.
Work reaching us from Frankfurt is mostly tower office floors, trading and call floors, data and plant rooms, hotels, studios, clinics.
- Towers full of glass Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
- Speech privacy is a business requirement On banking and trading floors the issue is not comfort, it is who can hear what. Absorption plus masking beats absorption alone every time.
- Plant rooms and equipment halls Generators, chillers and cooling plant sit close to occupied space and close to neighbours. Mass and a resilient break do more than any lining.
- 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 Frankfurt.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Frankfurt, mechanical ventilation with heat recovery is standard in newer stock, so duct-borne noise and terminal unit noise are the sources rather than open windows.
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 Frankfurt, concert halls, church buildings and civic Saal spaces are long-reverberation rooms where any intervention has to be reversible and visually disciplined.
Feature wall only. Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Frankfurt, school and university buildings are built to a high thermal standard with hard, cleanable surfaces. Speech clarity in classrooms and long corridors is where the acoustic budget goes.
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 Frankfurt 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 / On the ground
What we see driving Frankfurt briefs
- Towers full of glass
Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
- Speech privacy is a business requirement
On banking and trading floors the issue is not comfort, it is who can hear what. Absorption plus masking beats absorption alone every time.
- Plant rooms and equipment halls
Generators, chillers and cooling plant sit close to occupied space and close to neighbours. Mass and a resilient break do more than any lining.
- Trade fair and hotel programmes
Messe dates do not move. We give honest dispatch and transit windows so a fit-out is not sitting waiting on a container that will not land in time.
- Assembly and performance rooms
Concert halls, church buildings and civic Saal spaces are long-reverberation rooms where any intervention has to be reversible and visually disciplined.
- School and campus buildings
School and university buildings are built to a high thermal standard with hard, cleanable surfaces. Speech clarity in classrooms and long corridors is where the acoustic budget goes.
04 / Room by room
Where the money goes on a Frankfurt project
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
- 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
- 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. On banking and trading floors the issue is not comfort, it is who can hear what. Absorption plus masking beats absorption alone every time.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- 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
-
Rear wall
The single worst surface in most halls, and the first one to treat. Generators, chillers and cooling plant sit close to occupied space and close to neighbours. Mass and a resilient break do more than any lining.
- 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
- Ceiling baffles and clouds, ASTM C423
For a Frankfurt interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
Durability in Frankfurt, before acoustics is discussed
Frankfurt 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.
On a Frankfurt job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

Six mistakes that turn into a second fit-out
-
Absorbing the whole room and losing the back rows
Small on the drawing, expensive on site, and almost always found after handover.
-
Adding speakers to fix a reverberation problem
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Frankfurt job
Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
05 / Route to site
Getting it to Frankfurt, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hamburg or Rotterdam by sea, or Frankfurt airport when the date demands it |
| Dispatch | 4 to 7 working days |
| Freight | Sea, or air into FRA |
| 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.
Sea freight into Hamburg or Rotterdam, then road along the Rhine corridor. Air freight into Frankfurt for samples, replacements and genuinely urgent quantities.
Questions from Frankfurt projects
What makes auditorium acoustics and soundproofing different in Frankfurt?
Concert halls, church buildings and civic Saal spaces are long-reverberation rooms where any intervention has to be reversible and visually disciplined. Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
Where should the budget go first on a Frankfurt 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 Frankfurt?
No. We manufacture in India and supply into Frankfurt. 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 Frankfurt site?
ships from: Palwal, Haryana, India, arrives at: Hamburg or Rotterdam by sea, or Frankfurt airport when the date demands it, 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.
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.
