School and classroom acoustics in Berlin
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. 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.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

What you are buying, and what it fixes in Berlin
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
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.
Work reaching us from Berlin is mostly altbau flats, studios, clubs, startup offices, schools, clinics.
- Altbau floors Timber joists with fill between them pass footfall and speech. Adding mass and a resilient layer works better than anything fixed to the ceiling underneath.
- Club and live venues Berlin nightlife runs long hours beside housing. Low frequency containment is the whole job, and it is structural, not decorative.
- Courtyard buildings Hinterhof layouts bounce plant noise and voices between facing windows, which turns one noisy unit into a block wide problem.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school acoustics are on the main product page. This page covers what that means for a project in Berlin.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Berlin, 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.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 2
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Berlin, concert halls, church buildings and civic Saal spaces are long-reverberation rooms where any intervention has to be reversible and visually disciplined.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Berlin, 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.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
Architects working in Berlin 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 / In this market
What we see driving Berlin briefs
- Altbau floors
Timber joists with fill between them pass footfall and speech. Adding mass and a resilient layer works better than anything fixed to the ceiling underneath.
- Club and live venues
Berlin nightlife runs long hours beside housing. Low frequency containment is the whole job, and it is structural, not decorative.
- Courtyard buildings
Hinterhof layouts bounce plant noise and voices between facing windows, which turns one noisy unit into a block wide problem.
- Cold winters, sealed rooms
Tight, well insulated rooms sound dead in the wrong way. Balanced absorption matters as much as isolation.
- 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
What each space in a Berlin project needs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Timber joists with fill between them pass footfall and speech. Adding mass and a resilient layer works better than anything fixed to the ceiling underneath.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Wood wool acoustic panels, 20 mm
- Acoustic carpet and rugs, High density polyester
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. Berlin nightlife runs long hours beside housing. Low frequency containment is the whole job, and it is structural, not decorative.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Wood wool acoustic panels, 400 kg per cubic metre
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Hinterhof layouts bounce plant noise and voices between facing windows, which turns one noisy unit into a block wide problem.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Acoustic carpet and rugs, 64 sq ft per pack
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate and durability
The Berlin climate decides the material list
Berlin 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 Berlin job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
Panels at child height where they get damaged
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating one classroom and leaving the corridor
This is the one that comes back as a second fit-out rather than a snag.
-
Choosing a product that cannot take a football
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Treating it as a generic Berlin job
Timber joists with fill between them pass footfall and speech. Adding mass and a resilient layer works better than anything fixed to the ceiling underneath.

Questions from Berlin projects
What makes school and classroom acoustics different in Berlin?
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. Timber joists with fill between them pass footfall and speech. Adding mass and a resilient layer works better than anything fixed to the ceiling underneath.
Where should the budget go first on a Berlin project?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
Do you have an office or installation team in Berlin?
No. We manufacture in India and supply into Berlin. 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 Berlin site?
ships from: Palwal, Haryana, India, arrives at: Hamburg or Bremerhaven, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved and custom colours take longer, and we say so before you order.
What goes wrong most often on this kind of project?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
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.
