Venue and restaurant acoustics in Hanoi
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other. Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
- Containment
- Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
- Table level comfort
- Absorption at the ceiling so guests stop raising their voices at each other.
- Entrance and service
- Doors, lobbies and extract paths, which is where most of the leakage actually is.

01 / What it is
The material, and what it actually does on a Hanoi job
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other.
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.
- Containment Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for venue soundproofing are on the main product page. This page covers what that means for a project in Hanoi.

02 / The build-up
The build-up, layer by layer
-
Layer 1
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, split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Hanoi, function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
Feature wall only. Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Hanoi, classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What we see driving Hanoi briefs
- 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
-
Containment
Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. 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.
- 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
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
-
Table level comfort
Absorption at the ceiling so guests stop raising their voices at each other. Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- 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
- Wooden slat acoustic panels, 14, 16 and 18 mm
-
Entrance and service
Doors, lobbies and extract paths, which is where most of the leakage actually is. Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic panels, ASTM C423
- Wooden slat acoustic panels, 96 sq ft per unit
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate
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 / Straight talk
Where this kind of project usually fails
-
Panels on the wall as a neighbour noise solution
It sounds like a small detail until the room is finished and the complaint arrives.
-
A lobby with both doors able to open at once
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Extract ducting that bypasses every wall you built
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
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.

| Dispatch | 4 to 7 working days |
| Freight | Sea via Haiphong |
| 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.

Questions from Hanoi projects
What makes venue and restaurant acoustics 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?
Containment. Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Table level comfort. Absorption at the ceiling so guests stop raising their voices at each other.
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?
Panels on the wall as a neighbour noise solution. A lobby with both doors able to open at once.
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
Send a plan and a section, get a real build-up
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
