Hospital and healthcare acoustics in San Francisco
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed. 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.
- Consulting room privacy
- Speech privacy between rooms, which is partition, door and ceiling void work.
- Ward noise floor
- Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
- Cleanability
- Non shedding, non absorbent surfaces that survive a cleaning regime.

What you are buying, and what it fixes in San Francisco
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed.
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.
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.
- Consulting room privacy Speech privacy between rooms, which is partition, door and ceiling void work.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for healthcare acoustics 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
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. 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.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. 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.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
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 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.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
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.

What decides the build-up in San Francisco
- 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.
- Plant and HVAC
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.

Where the money goes on a San Francisco project
-
Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Acoustic carpet and rugs, 4 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Ward noise floor
Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling. 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.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Acoustic carpet and rugs, High density polyester
- Acoustic panels, ASTM C423
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Seismic detailing requires junctions that stay flexible, so the acoustic layer must not stiffen across them.
- PET felt acoustic panels, 4 to 24 mm
- 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 San Francisco climate rules in and rules out
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.
On a San Francisco job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Where this kind of project usually fails
-
Fabric wrapped products in a clinical area
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Absorption used where privacy was the requirement
If the complaint is being overheard, no amount of absorption inside the room will fix it. That is a partition job and we will say so.
-
Ceiling void left open above a partition
A treated wall under a bare hard ceiling gives you a fraction of the reduction you paid for, and the room still sounds wrong.
-
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 / Supply
Getting it to San Francisco, with real dates
| 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 hospital and healthcare acoustics different 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. 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?
Consulting room privacy. Speech privacy between rooms, which is partition, door and ceiling void work. Ward noise floor. Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
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?
Fabric wrapped products in a clinical area. Absorption used where privacy was the requirement.
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.
