Venue and restaurant acoustics in Sao Paulo
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. Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
- 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.

What this material is and where it earns its place in Sao Paulo
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.
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
Work reaching us from Sao Paulo is mostly corporate towers, apartments, restaurants, hotels, clinics, studios, schools.
- Towers block, interiors ring Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- Traffic and helicopters Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- Impact between apartments Hard floors over slabs pass footfall down. The underlay has to go in before the finish, not after the complaint.
- 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 Sao Paulo.

02 / The build-up
What goes where, from the structure in
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Sao Paulo, split units and VRF, with condensers in light wells and on facades close to bedrooms.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 Sao Paulo, churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
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 Sao Paulo, classrooms are concrete and tile with high ceilings and hard floors, and covered play areas amplify everything.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
If you are specifying for a Sao Paulo project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / On the ground
What we see driving Sao Paulo briefs
- Towers block, interiors ring
Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- Traffic and helicopters
Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- Impact between apartments
Hard floors over slabs pass footfall down. The underlay has to go in before the finish, not after the complaint.
- Santos, then the climb inland
The port leg and the road leg are separate costs and separate time. We quote both rather than one.
- Assembly and performance rooms
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.

Room by room, on a typical Sao Paulo job
-
Containment
Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- 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. Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- 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. Hard floors over slabs pass footfall down. The underlay has to go in before the finish, not after the complaint.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic panels, ASTM C423
- Wooden slat acoustic panels, 96 sq ft per unit
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate and durability
Durability in Sao Paulo, before acoustics is discussed
Sao Paulo 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 Sao Paulo job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Six mistakes that turn into a second fit-out
-
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
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.
-
Extract ducting that bypasses every wall you built
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Treating it as a generic Sao Paulo job
Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
05 / Route to site
How material reaches a Sao Paulo site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Santos, then road up to Sao Paulo |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Santos |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Santos, then road up to Sao Paulo. Air freight for samples and urgent quantities.
Questions from Sao Paulo projects
What makes venue and restaurant acoustics different in Sao Paulo?
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level. Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
Where should the budget go first on a Sao Paulo 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 Sao Paulo?
No. We manufacture in India and supply into Sao Paulo. 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 Sao Paulo site?
ships from: Palwal, Haryana, India, arrives at: Santos, then road up to Sao Paulo, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
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.
