Auditorium acoustics and soundproofing in Brisbane
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. School halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
- 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 Brisbane 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.
School halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
Work reaching us from Brisbane is mostly timber housing and renovations, apartments, offices, venues, schools, clinics.
- Houses raised on stumps A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
- Subtropical humidity PET felt does not absorb moisture, shed fibre or feed mould, which matters through a humid summer where mineral products sag.
- Apartments built light and fast The same separating detail repeated across a development. Worth solving on the drawing rather than after settlement.
- 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 Brisbane.
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 Brisbane, ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-

Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Brisbane, school halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
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 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Brisbane, school buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Brisbane usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

What decides the build-up in Brisbane
- Houses raised on stumps
A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
- Subtropical humidity
PET felt does not absorb moisture, shed fibre or feed mould, which matters through a humid summer where mineral products sag.
- Apartments built light and fast
The same separating detail repeated across a development. Worth solving on the drawing rather than after settlement.
- A long sea leg
One of the longer routes we run. Ordering to a real schedule matters, so we quote the full window rather than the port date.
- Assembly and performance rooms
School halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
- School and campus buildings
School buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
- 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. PET felt does not absorb moisture, shed fibre or feed mould, which matters through a humid summer where mineral products sag.
- 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. The same separating detail repeated across a development. Worth solving on the drawing rather than after settlement.
- 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 and durability
Why the climate in Brisbane changes the material, not the target
Brisbane 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.
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.

Six mistakes that turn into a second fit-out
-
Absorbing the whole room and losing the back rows
This is the one that comes back as a second fit-out rather than a snag.
-
Adding speakers to fix a reverberation problem
This is the one that comes back as a second fit-out rather than a snag.
-
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 Brisbane job
A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
05 / Logistics
Supply into Brisbane, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Port of Brisbane, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Port of Brisbane |
| 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 the Port of Brisbane, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Brisbane projects
What makes auditorium acoustics and soundproofing different in Brisbane?
School halls, community centres and church buildings carry assembly, performance and sport in one hard volume. A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
Where should the budget go first on a Brisbane 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 Brisbane?
No. We manufacture in India and supply into Brisbane. 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 Brisbane site?
ships from: Palwal, Haryana, India, arrives at: Port of Brisbane, then a short road run 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.
