Auditorium acoustics and soundproofing in Atlanta
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 / What it is
The material, and what it actually does on a Atlanta job
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 Atlanta is mostly production stages, edit and mix rooms, offices, schools, clinics, restaurants, home theatres.
- Production rooms have no tolerance A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
- Warehouse conversions Big metal and concrete shells make superb volume and terrible acoustics. Rain on a metal deck and traffic outside both get in, and the inside is completely live.
- Light frame residential Homes and apartments here are gypsum on studs, which passes low frequency far more easily than masonry. Added mass and a decoupled layer do the work, not absorption.
- 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 Atlanta.
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 Atlanta, 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.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Atlanta, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
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 Atlanta, 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.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
We would rather argue about the build-up at design stage than on site. See how we support architects.

What decides the build-up in Atlanta
- Production rooms have no tolerance
A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
- Warehouse conversions
Big metal and concrete shells make superb volume and terrible acoustics. Rain on a metal deck and traffic outside both get in, and the inside is completely live.
- Light frame residential
Homes and apartments here are gypsum on studs, which passes low frequency far more easily than masonry. Added mass and a decoupled layer do the work, not absorption.
- Savannah, then the road
The container lands at the coast and drives in. We quote the sea leg and the road leg separately so the programme is built on real dates.
- 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.
04 / Room by room
What each space in a Atlanta project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
- 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
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Big metal and concrete shells make superb volume and terrible acoustics. Rain on a metal deck and traffic outside both get in, and the inside is completely live.
- Wood wool acoustic panels, 20 mm
- PET felt acoustic panels, 4 to 24 mm
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Homes and apartments here are gypsum on studs, which passes low frequency far more easily than masonry. Added mass and a decoupled layer do the work, not absorption.
- Wood wool acoustic panels, 400 kg per cubic metre
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Acoustic carpet and rugs, 64 sq ft per pack
For a Atlanta interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate
The Atlanta climate decides the material list
Atlanta 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 Atlanta job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Atlanta job
A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
05 / Getting it there
Supply into Atlanta, start to site
| Ships from | Palwal, Haryana, India |

| Dispatch | 4 to 7 working days |
| Freight | Sea via Savannah |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg to the US East Coast is long, so plan the full door to door window. We give real dates rather than optimistic ones.
Sea freight into Savannah, then road to Atlanta. Air freight for samples, colour approvals and genuinely urgent quantities.
Questions from Atlanta projects
What makes auditorium acoustics and soundproofing different in Atlanta?
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both. A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
Where should the budget go first on a Atlanta 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 Atlanta?
No. We manufacture in India and supply into Atlanta. 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 Atlanta site?
ships from: Palwal, Haryana, India, arrives at: Savannah, then road to Atlanta, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg to the US East Coast is long, so plan the full door to door window. We give real dates rather than 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.
