Cinema and multiplex soundproofing in Hanoi
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes. Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
- Screen to screen
- Independent construction between auditoria, with services broken at the line.
- In room response
- Heavy absorption on side and rear walls so the mix is heard as intended.
- Plant and projection
- Equipment noise into the auditorium, treated at source.

01 / The material
What this material is and where it earns its place in Hanoi
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes.
Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
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.
- Screen to screen Independent construction between auditoria, with services broken at the line.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for cinema soundproofing are on the main product page. This page covers what that means for a project in Hanoi.
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 Hanoi, split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
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 carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Hanoi, function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Hanoi, classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
For a Hanoi practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / Local conditions
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.
- Assembly and performance rooms
Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.

What each space in a Hanoi project needs
-
Screen to screen
Independent construction between auditoria, with services broken at the line. 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.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic panels, ASTM C423
-
Plant and projection
Equipment noise into the auditorium, treated at source. Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber

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
Durability in Hanoi, before acoustics is discussed
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.
On a Hanoi job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Read this first
The six errors that cost the most
-
A shared service void running across the wall line
A treated wall under a bare hard ceiling gives you a fraction of the reduction you paid for, and the room still sounds wrong.
-
Treating the auditorium to fix bleed from the next screen
It sounds like a small detail until the room is finished and the complaint arrives.
-
Doors and lobbies specified late and undersized
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
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.
05 / Getting it there

Questions from Hanoi projects
What makes cinema and multiplex soundproofing different in Hanoi?
Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music. 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?
Screen to screen. Independent construction between auditoria, with services broken at the line. In room response. Heavy absorption on side and rear walls so the mix is heard as intended.
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?
A shared service void running across the wall line. Treating the auditorium to fix bleed from the next screen.
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.
