Home theatre soundproofing and acoustics in Brisbane
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. Timber frame in detached housing, concrete in apartments. Apartment party walls and slabs are the source of most complaints, and impact noise needs a resilient layer.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.

01 / The material
What you are buying, and what it fixes in Brisbane
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
Timber frame in detached housing, concrete in apartments. Apartment party walls and slabs are the source of most complaints, and impact noise needs a resilient layer.
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.
- Containment Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in Brisbane.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Brisbane, ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
Layer 2
Acoustic foam and BassBloc
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing. In Brisbane, school halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Brisbane, school buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.
Double layer at a doorway. Two curtains with an air gap where a single layer will not reach the target.
If you are specifying for a Brisbane project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / On the ground
The Brisbane conditions that change the answer
- 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.
- The housing stock
Timber frame in detached housing, concrete in apartments. Apartment party walls and slabs are the source of most complaints, and impact noise needs a resilient layer.
04 / Room by room
What each space in a Brisbane project needs
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. 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.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic foam and BassBloc, 20 mm
- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. PET felt does not absorb moisture, shed fibre or feed mould, which matters through a humid summer where mineral products sag.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Acoustic carpet and rugs, Felt
-
Reflections
Side wall and ceiling first reflection points at the seating position. The same separating detail repeated across a development. Worth solving on the drawing rather than after settlement.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic foam and BassBloc, 100 to 500 Hz
- Acoustic carpet and rugs, 64 sq ft per pack
For a Brisbane interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
Durability in Brisbane, before acoustics is discussed
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.

The six errors that cost the most
-
Foam on the walls as a soundproofing measure
This is the one that comes back as a second fit-out rather than a snag.
-
A standard door on a room built to hold bass
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.

Treating before the room is sealed
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.

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 / Supply
Getting it to Brisbane, with real dates

|---|---|
| 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 home theatre soundproofing and acoustics different in Brisbane?
Timber frame in detached housing, concrete in apartments. Apartment party walls and slabs are the source of most complaints, and impact noise needs a resilient layer. 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?
Containment. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
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?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
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
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.
