Home theatre soundproofing and acoustics in Jakarta
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. Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households.
- 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 / What it is
The material, and what it actually does on a Jakarta job
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.
Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households.
Work reaching us from Jakarta is mostly towers and offices, apartments, hotels, hospitals, schools, studios.
- The port is in the city Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
- Noise arrives from outside Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
- Concrete towers, live interiors The structure blocks well. The problem is tile, glass and stone inside making the room ring.
- 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 Jakarta.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Jakarta, split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
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 Jakarta, places of worship, function halls and community buildings are large hard rooms carrying amplified speech and music.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Jakarta, classrooms are hard, naturally ventilated and open to corridor and street noise, so absorption alone will not fix intelligibility.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
If you are specifying for a Jakarta project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What we see driving Jakarta briefs
- The port is in the city
Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
- Noise arrives from outside
Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
- Concrete towers, live interiors
The structure blocks well. The problem is tile, glass and stone inside making the room ring.
- Standby generation
Power backup sits close to occupied space in most commercial buildings and runs often enough to matter.
- The housing stock
Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households.
04 / Room by room
Space by space, for Jakarta briefs
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- Soundproof curtains, 10 to 12 mm
- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Soundproof curtains, 5.5 kg per sq m
- Acoustic carpet and rugs, Felt
-
Reflections
Side wall and ceiling first reflection points at the seating position. The structure blocks well. The problem is tile, glass and stone inside making the room ring.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Soundproof curtains, Up to 30 dB
- 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 / Durability
The Jakarta climate decides the material list
Jakarta is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
On a Jakarta job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Where this kind of project usually fails
-
Foam on the walls as a soundproofing measure
It sounds like a small detail until the room is finished and the complaint arrives.
-
A standard door on a room built to hold bass
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Treating before the room is sealed
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic Jakarta job
Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
05 / Logistics
Getting it to Jakarta, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Tanjung Priok, then a short road run into the city |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Tanjung Priok |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Tanjung Priok, then a short road run into the city. Air freight for samples and urgent quantities.
Questions from Jakarta projects
What makes home theatre soundproofing and acoustics different in Jakarta?
Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households. Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
Where should the budget go first on a Jakarta 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 Jakarta?
No. We manufacture in India and supply into Jakarta. 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 Jakarta site?
ships from: Palwal, Haryana, India, arrives at: Tanjung Priok, then a short road run into the city, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
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.
