Office acoustics and soundproofing in Hanoi
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

What this is, and what it changes in a Hanoi room
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
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.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Hanoi.

02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Hanoi, split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 2
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Hanoi, function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Hanoi, classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
What the buildings in Hanoi do to the specification
- 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.
- Plant and HVAC
Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.

Room by room, on a typical Hanoi job
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. 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.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- Acoustic carpet and rugs, 4 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
- Acoustic panels, ASTM C423
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
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 / Conditions
What the Hanoi climate rules in and rules out
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 / Worth knowing
Six mistakes that turn into a second fit-out
-
Lining every wall while leaving the ceiling bare
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
Treating a privacy problem with absorption
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Glass cabins specified without a door and head detail
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.

Questions from Hanoi projects
What makes office acoustics and soundproofing different in Hanoi?
Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts. 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?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
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?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
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.
