Venue and restaurant acoustics in San Francisco
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, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
- 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.

The material, and what it actually does on a San Francisco 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.
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Work reaching us from San Francisco is mostly victorian conversions, tech offices, apartments, studios, restaurants, clinics.
- Timber Victorians Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
- Depth costs real money At local rates a wall growing into the room is a significant number. A dense thin membrane usually beats a thicker framed build-up on total cost.
- Designed to move Seismic detailing requires junctions that stay flexible, so the acoustic layer must not stiffen across them.
- 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 San Francisco.

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 San Francisco, packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
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 San Francisco, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In San Francisco, public school buildings run long corridors with hard floors and lay-in tile ceilings that were chosen for cost, not for speech. Classroom reverberation and corridor spill are the two complaints, and both respond to ceiling area rather than wall panels.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
For a San Francisco practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / In this market
The San Francisco conditions that change the answer
- Timber Victorians
Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
- Depth costs real money
At local rates a wall growing into the room is a significant number. A dense thin membrane usually beats a thicker framed build-up on total cost.
- Designed to move
Seismic detailing requires junctions that stay flexible, so the acoustic layer must not stiffen across them.
- Oakland is close
A short road leg after the port keeps landed cost and timing predictable.
- Assembly and performance rooms
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.

Where the money goes on a San Francisco project
-
Containment
Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
- 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
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Acoustic carpet and rugs, High density polyester
-
Table level comfort
Absorption at the ceiling so guests stop raising their voices at each other. At local rates a wall growing into the room is a significant number. A dense thin membrane usually beats a thicker framed build-up on total cost.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Acoustic carpet and rugs, Felt
-
Entrance and service
Doors, lobbies and extract paths, which is where most of the leakage actually is. Seismic detailing requires junctions that stay flexible, so the acoustic layer must not stiffen across them.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wooden slat acoustic panels, 14, 16 and 18 mm
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
The San Francisco climate decides the material list
San Francisco is mild summers and cold, wet winters, and that narrows the material list before acoustics is discussed.
Cold external walls and long heating seasons make condensation behind a lining the thing to design out. PET felt is unaffected by damp air.
The failure we design against here is condensation and cold bridging behind new linings.
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.

Where this kind of project usually fails
-
Panels on the wall as a neighbour noise solution
This is the one that comes back as a second fit-out rather than a snag.
-
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 San Francisco job
Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
05 / Getting it there
How material reaches a San Francisco site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Oakland, then a short road run across the bay |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Oakland |
| 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 Oakland, then a short road run to site. Air freight for samples and urgent quantities.
Questions from San Francisco projects
What makes venue and restaurant acoustics different in San Francisco?
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both. Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
Where should the budget go first on a San Francisco 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 San Francisco?
No. We manufacture in India and supply into San Francisco. 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 San Francisco site?
ships from: Palwal, Haryana, India, arrives at: Oakland, then a short road run across the bay, 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.
Next step
Tell us the room, we will tell you the build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
