Auditorium acoustics and soundproofing in Madrid
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. Churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
- 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 / What it is
The product, described honestly, for a Madrid brief
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.
Churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
Work reaching us from Madrid is mostly ensanche apartments, Castellana office floors, restaurants, hotels, clinics, studios, schools.
- Ensanche blocks share everything The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- Castellana floors have nothing soft Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- A city that eats and drinks late Bars and restaurants run long hours directly under apartments. The complaint is almost always low frequency and footfall, and it arrives fast.
- 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 Madrid.
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 Madrid, split and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Madrid, churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Madrid, school buildings are concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
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 Madrid
- Ensanche blocks share everything
The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- Castellana floors have nothing soft
Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- A city that eats and drinks late
Bars and restaurants run long hours directly under apartments. The complaint is almost always low frequency and footfall, and it arrives fast.
- Closed up against the heat
Once a room is sealed and air conditioned it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- Assembly and performance rooms
Churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
- School and campus buildings
School buildings are concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- 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. Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- 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. Bars and restaurants run long hours directly under apartments. The complaint is almost always low frequency and footfall, and it arrives fast.
- 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
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
What the Madrid climate rules in and rules out
Madrid is hot dry summers and mild wet winters, and that narrows the material list before acoustics is discussed.
The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.
The failure we design against here is seasonal movement in timber and winter damp in unheated 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 / Worth knowing
The six errors that cost the most
-
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Madrid job
The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
05 / Getting it there
How material reaches a Madrid site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Valencia or Barcelona, then road inland to Madrid |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then road inland |
| 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.
Sea freight into Valencia or Barcelona, then road inland to Madrid. Air freight for samples and urgent quantities.
Questions from Madrid projects
What makes auditorium acoustics and soundproofing different in Madrid?
Churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times. The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
Where should the budget go first on a Madrid 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 Madrid?
No. We manufacture in India and supply into Madrid. 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 Madrid site?
ships from: Palwal, Haryana, India, arrives at: Valencia or Barcelona, then road inland to Madrid, 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.
Next step
Drawings in, BOQ and a delivered date out
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
