Home theatre soundproofing and acoustics in Hanoi
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. Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout.
- 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.
- Quote
- From a plan and a section, within 48 hours

The product, described honestly, for a Hanoi brief
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.
Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout.
Work reaching us from Hanoi is mostly manufacturing plants, tube houses and apartments, offices, hotels, schools, clinics.
- Narrow, deep buildings The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides.
- Continuous street noise Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- New manufacturing at pace Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- 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 Hanoi.
02 / The build-up
What goes where, from the structure in
-
Layer 1
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 Hanoi, split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
-
Layer 2
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Hanoi, function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Hanoi, classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
Full height with return. Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
If you are specifying for a Hanoi project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.

What decides the build-up in Hanoi
- Narrow, deep buildings
The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides.
- Continuous street noise
Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- New manufacturing at pace
Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- Hot, humid, monsoon
PET felt does not absorb moisture or feed mould, which matters where mineral products sag in a couple of seasons.
- The housing stock
Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout.

What each space in a Hanoi project needs
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides.
- Acoustic foam and BassBloc, 1800 x 900 mm

- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.

Reflections
Side wall and ceiling first reflection points at the seating position. Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber

For a Hanoi interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Durability
The Hanoi climate decides the material list
Hanoi 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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Straight talk
Where this kind of project usually fails
-
Foam on the walls as a soundproofing measure
Small on the drawing, expensive on site, and almost always found after handover.
-
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

Treating it as a generic Hanoi job
The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides.

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.

Questions from Hanoi projects
What makes home theatre soundproofing and acoustics different in Hanoi?
Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout. The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides.
Where should the budget go first on a Hanoi 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 Hanoi?
No. We manufacture in India and supply into Hanoi. 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 Hanoi site?
ships from: Palwal, Haryana, India, arrives at: Haiphong, then road into Hanoi, 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.

Drawings in, BOQ and a delivered date out
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
