Recording studio acoustics and soundproofing in Hanoi
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later. A fast growing content scene works out of rooms in tube houses and commercial floors with thin partitions.
- Isolation
- A measured background level, agreed before anything is bought.
- Low frequency
- Corner and boundary absorption with real depth, not surface foam.
- Early reflections
- Controlled at the mix position, and only there.

01 / The material
What you are buying, and what it fixes in Hanoi
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later.
A fast growing content scene works out of rooms in tube houses and commercial floors with thin partitions.
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.
- Isolation A measured background level, agreed before anything is bought.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for studio soundproofing 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
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
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.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
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.
- The studio and content scene
A fast growing content scene works out of rooms in tube houses and commercial floors with thin partitions.

Isolation
A measured background level, agreed before anything is bought. 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
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Soundproof curtains, 5.5 kg per sq m
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- Acoustic foam and BassBloc, 20 mm
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Soundproof curtains, Up to 30 dB
-
Early reflections
Controlled at the mix position, and only there. 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
- Soundproof curtains, 30
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Straight talk
The six errors that cost the most
-
Buying foam to solve an isolation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating the room before the shell is isolated
This is the one that comes back as a second fit-out rather than a snag.
-
Killing the room completely and calling it controlled
A room can be over-treated. Past the target it stops sounding controlled and starts sounding dead, and you paid for that.
-
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.

Supply into Hanoi, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Haiphong, then road into Hanoi |
| 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 recording studio acoustics and soundproofing different in Hanoi?
A fast growing content scene works out of rooms in tube houses and commercial floors with thin partitions. 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?
Isolation. A measured background level, agreed before anything is bought. Low frequency. Corner and boundary absorption with real depth, not surface foam.
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?
Buying foam to solve an isolation problem. Treating the room before the shell is isolated.
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
Drawings in, BOQ and a delivered date out
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.
