Auditorium acoustics and soundproofing in Netherlands
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 you are buying, and what it fixes in Netherlands
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 Netherlands is mostly apartments, offices, schools, healthcare, studios, hospitality.
- Timber floors in canal houses Old narrow houses carry footfall down every floor. A resilient layer under the finish does more than a treatment applied below.
- Lightweight new build Efficient construction means less mass. Where mass is missing, a dense membrane is usually the cheapest honest fix.
- Recycled content matters here PET felt is made from recycled bottle flake, which is the first question most Dutch specifiers ask and the easiest one for us to answer.
- 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 Netherlands.
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 Netherlands, balanced mechanical ventilation is standard, so duct and terminal unit noise replace open window noise.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Netherlands, 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
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Netherlands, school buildings are well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
What decides the build-up in Netherlands
- Timber floors in canal houses
Old narrow houses carry footfall down every floor. A resilient layer under the finish does more than a treatment applied below.
- Lightweight new build
Efficient construction means less mass. Where mass is missing, a dense membrane is usually the cheapest honest fix.
- Recycled content matters here
PET felt is made from recycled bottle flake, which is the first question most Dutch specifiers ask and the easiest one for us to answer.
- Damp, mild climate
Our felt does not absorb moisture, shed fibre or feed mould, which suits cold external walls and sealed rooms.
- 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.

Room by room, on a typical Netherlands job

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Old narrow houses carry footfall down every floor. A resilient layer under the finish does more than a treatment applied below.
- Wood wool acoustic panels, 1200 x 600 mm
- 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. Efficient construction means less mass. Where mass is missing, a dense membrane is usually the cheapest honest fix.
- Wood wool acoustic panels, 20 mm
- 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. PET felt is made from recycled bottle flake, which is the first question most Dutch specifiers ask and the easiest one for us to answer.
- Wood wool acoustic panels, 400 kg per cubic metre
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Ceiling baffles and clouds, ASTM C423
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 / Durability
The Netherlands climate decides the material list
Netherlands 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 Netherlands project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
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 Netherlands job
Old narrow houses carry footfall down every floor. A resilient layer under the finish does more than a treatment applied below.
05 / Getting it there
Supply into Netherlands, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Rotterdam, then a short road run to site |
| 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 and custom colours take longer, and we say so before you order.
Sea freight into Rotterdam, then road to site. Being close to the port keeps inland cost low. Air freight for samples and urgent quantities.
Questions from Netherlands projects
What makes auditorium acoustics and soundproofing different in Netherlands?
Church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout. Old narrow houses carry footfall down every floor. A resilient layer under the finish does more than a treatment applied below.
Where should the budget go first on a Netherlands 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 Netherlands?
No. We manufacture in India and supply into Netherlands. 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 Netherlands site?
ships from: Palwal, Haryana, India, arrives at: Rotterdam, then a short road run to site, 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?
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.

Send the drawings, get a straight answer
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
