Auditorium acoustics and soundproofing in Phoenix
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, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
- 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 Phoenix
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, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Work reaching us from Phoenix is mostly plant and equipment rooms, offices, multifamily, schools, clinics, home theatres.
- Cooling plant runs almost year round Large units working continuously next to occupied space is the defining acoustic condition here. That is mass, isolation and duct treatment, not panels on a wall.
- Block and stucco, not just timber A lot of construction here is masonry block rather than light frame, which changes the answer. We ask what the wall actually is before quoting anything.
- Sealed buildings, all summer Nothing opens for months. Sound stops escaping and accumulates, so absorption inside has to be balanced rather than piled on.
- 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 Phoenix.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Phoenix, packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
Slats on felt backing. The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Phoenix, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Phoenix, public school buildings run long corridors with hard floors and lay-in tile ceilings that were chosen for cost, not for speech. Classroom reverberation and corridor spill are the two complaints, and both respond to ceiling area rather than wall panels.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
We would rather argue about the build-up at design stage than on site. See how we support architects.

What we see driving Phoenix briefs
- Cooling plant runs almost year round
Large units working continuously next to occupied space is the defining acoustic condition here. That is mass, isolation and duct treatment, not panels on a wall.
- Block and stucco, not just timber
A lot of construction here is masonry block rather than light frame, which changes the answer. We ask what the wall actually is before quoting anything.
- Sealed buildings, all summer
Nothing opens for months. Sound stops escaping and accumulates, so absorption inside has to be balanced rather than piled on.
- Heat does not bother our material
PET felt does not sag, shed fibre or break down at high temperatures, which matters in roof voids and plant spaces that get genuinely hot.
- Assembly and performance rooms
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
- School and campus buildings
Public school buildings run long corridors with hard floors and lay-in tile ceilings that were chosen for cost, not for speech. Classroom reverberation and corridor spill are the two complaints, and both respond to ceiling area rather than wall panels.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Large units working continuously next to occupied space is the defining acoustic condition here. That is mass, isolation and duct treatment, not panels on a wall.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- 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. A lot of construction here is masonry block rather than light frame, which changes the answer. We ask what the wall actually is before quoting anything.
- Wood wool acoustic panels, 20 mm
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 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. Nothing opens for months. Sound stops escaping and accumulates, so absorption inside has to be balanced rather than piled on.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- Ceiling baffles and clouds, ASTM C423
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Durability
The Phoenix climate decides the material list
Phoenix 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.
On a Phoenix job with a consultant involved, our part is material that matches the submitted data. See 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
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 Phoenix job
Large units working continuously next to occupied space is the defining acoustic condition here. That is mass, isolation and duct treatment, not panels on a wall.
05 / Supply
Getting it to Phoenix, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Long Beach or Los Angeles, then road across to Phoenix |
| Dispatch | 4 to 7 working days |
| Freight | Sea via the West Coast |
| 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 Long Beach or Los Angeles, then road across to Phoenix. Air freight for samples and urgent quantities.
Questions from Phoenix projects
What makes auditorium acoustics and soundproofing different in Phoenix?
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both. Large units working continuously next to occupied space is the defining acoustic condition here. That is mass, isolation and duct treatment, not panels on a wall.
Where should the budget go first on a Phoenix 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 Phoenix?
No. We manufacture in India and supply into Phoenix. 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 Phoenix site?
ships from: Palwal, Haryana, India, arrives at: Long Beach or Los Angeles, then road across to Phoenix, 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
Tell us the room, we will tell you the build-up
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.
