Auditorium acoustics and soundproofing in Amsterdam
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. Church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout.
- 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 Amsterdam 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.
Church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout.
Work reaching us from Amsterdam is mostly canal house apartments, hotels, offices in Zuid and Noord, studios, bars, clinics.
- Canal houses carry everything Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
- Listed facades, internal fixes only On a monument you cannot change the outside and often cannot change the structure. Everything has to be done from the inside, shallow, and ideally reversible.
- Venue noise limits are enforced Amsterdam operators live with real decibel and low frequency conditions on their permits, and the low end is what gets them into trouble. Containment is not optional here, it is the licence.
- 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 Amsterdam.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Amsterdam, balanced mechanical ventilation is standard, so duct and terminal unit noise replace open window noise.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Amsterdam, church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Amsterdam, school buildings are well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
Architects working in Amsterdam 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 we see driving Amsterdam briefs
- Canal houses carry everything
Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
- Listed facades, internal fixes only
On a monument you cannot change the outside and often cannot change the structure. Everything has to be done from the inside, shallow, and ideally reversible.
- Venue noise limits are enforced
Amsterdam operators live with real decibel and low frequency conditions on their permits, and the low end is what gets them into trouble. Containment is not optional here, it is the licence.
- Recycled content gets asked first
Our PET felt is made from recycled bottle flake. In Dutch tenders that question comes before the acoustic one, and it is the easiest one for us to answer honestly.
- Assembly and performance rooms
Church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout.
- School and campus buildings
School buildings are well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present.
04 / Room by room
What each space in a Amsterdam project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
- Wood wool acoustic panels, 1200 x 600 mm
- 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. On a monument you cannot change the outside and often cannot change the structure. Everything has to be done from the inside, shallow, and ideally reversible.
- Wood wool acoustic panels, 20 mm
- 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. Amsterdam operators live with real decibel and low frequency conditions on their permits, and the low end is what gets them into trouble. Containment is not optional here, it is the licence.
- Wood wool acoustic panels, 400 kg per cubic metre
- 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
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
The Amsterdam climate decides the material list
Amsterdam 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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Straight talk
Six mistakes that turn into a second fit-out
-
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
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 Amsterdam job
Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
05 / Logistics
Getting it to Amsterdam, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Rotterdam, then a short road run into the city |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Rotterdam |
| 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 tell you that before you order, not after.
Sea freight into Rotterdam, then road into Amsterdam. Being close to the port keeps the inland cost low. Air freight for samples and urgent quantities.
Questions from Amsterdam projects
What makes auditorium acoustics and soundproofing different in Amsterdam?
Church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout. Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
Where should the budget go first on a Amsterdam 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 Amsterdam?
No. We manufacture in India and supply into Amsterdam. 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 Amsterdam site?
ships from: Palwal, Haryana, India, arrives at: Rotterdam, then a short road run into the city, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we tell you that 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.
