Auditorium acoustics and soundproofing in Chile
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, theatres and event halls are hard volumes with 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.

What this material is and where it earns its place in Chile
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, theatres and event halls are hard volumes with long decay times.
Work reaching us from Chile is mostly offices, apartments, mining and industrial facilities, hotels, hospitals, schools.
- Seismic detailing comes first Movement joints have to stay free. An acoustic layer must respect the structural design rather than stiffen across it.
- Mining and industrial plant Remote facilities with continuous machinery and control rooms where alarms have to be understood. Enclosure and mass do that work.
- A very long country Site location changes the inland leg dramatically. We quote the road leg for your actual destination rather than an average.
- 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 Chile.
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 Chile, split units and central plant with condensers on facades and rooftops close to bedrooms.
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 Chile, church buildings, theatres and event halls are hard volumes with long decay times.
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 Chile, school buildings are hard surfaced with long corridors and gymnasiums doubling as assembly halls.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Chile 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 Chile briefs
- Seismic detailing comes first
Movement joints have to stay free. An acoustic layer must respect the structural design rather than stiffen across it.
- Mining and industrial plant
Remote facilities with continuous machinery and control rooms where alarms have to be understood. Enclosure and mass do that work.
- A very long country
Site location changes the inland leg dramatically. We quote the road leg for your actual destination rather than an average.
- Dry in the north, wet in the south
PET felt is stable in both. It does not absorb moisture or degrade in dry heat, which simplifies specifying across regions.
- Assembly and performance rooms
Church buildings, theatres and event halls are hard volumes with long decay times.
- School and campus buildings
School buildings are hard surfaced with long corridors and gymnasiums doubling as assembly halls.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Movement joints have to stay free. An acoustic layer must respect the structural design rather than stiffen across it.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- 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. Remote facilities with continuous machinery and control rooms where alarms have to be understood. Enclosure and mass do that work.
- 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
- Acoustic carpet and rugs, Felt
-

Rear wall
The single worst surface in most halls, and the first one to treat. Site location changes the inland leg dramatically. We quote the road leg for your actual destination rather than an average.
- 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
- 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 / Conditions
Durability in Chile, before acoustics is discussed
Chile is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
Where a consultant is already engaged on a Chile 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
It sounds like a small detail until the room is finished and the complaint arrives.
-
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
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating it as a generic Chile job
Movement joints have to stay free. An acoustic layer must respect the structural design rather than stiffen across it.
05 / Getting it there
How material reaches a Chile site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | San Antonio or Valparaíso, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via San Antonio |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into San Antonio or Valparaíso, then road to site. Air freight for samples and urgent quantities.
Questions from Chile projects
What makes auditorium acoustics and soundproofing different in Chile?
Church buildings, theatres and event halls are hard volumes with long decay times. Movement joints have to stay free. An acoustic layer must respect the structural design rather than stiffen across it.
Where should the budget go first on a Chile 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 Chile?
No. We manufacture in India and supply into Chile. 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 Chile site?
ships from: Palwal, Haryana, India, arrives at: San Antonio or Valparaíso, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
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
Send a plan and a section, get a real build-up
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.
