Hospital and healthcare acoustics in Los Angeles
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.

01 / The material
What this material is and where it earns its place in Los Angeles
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 Los Angeles is mostly post production and mix rooms, stages, offices, light frame housing, restaurants, schools.
- Production rooms have no tolerance A mix room or ADR stage either isolates or it does not. There is no partial credit, which is why the shell gets designed before any fabric is chosen.
- Light frame and stucco Housing here is gypsum on studs behind stucco, which passes low frequency far more easily than masonry. Mass and decoupling do the work.
- Designed to move Seismic detailing means junctions that must stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- 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 Los Angeles.
02 / The build-up
What goes where, from the structure in
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Los Angeles, 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.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Los Angeles, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 Los Angeles, 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.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
For a Los Angeles 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 Los Angeles
- Production rooms have no tolerance
A mix room or ADR stage either isolates or it does not. There is no partial credit, which is why the shell gets designed before any fabric is chosen.
- Light frame and stucco
Housing here is gypsum on studs behind stucco, which passes low frequency far more easily than masonry. Mass and decoupling do the work.
- Designed to move
Seismic detailing means junctions that must stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- The port is right here
Direct sea into Long Beach means no cross-country leg, which keeps both the landed cost and the date 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.

Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. A mix room or ADR stage either isolates or it does not. There is no partial credit, which is why the shell gets designed before any fabric is chosen.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- Acoustic carpet and rugs, 4 mm
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Ward noise floor
Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling. Housing here is gypsum on studs behind stucco, which passes low frequency far more easily than masonry. Mass and decoupling do the work.
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Seismic detailing means junctions that must stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
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
Why the climate in Los Angeles changes the material, not the target
Los Angeles is hot dry summers and mild wet winters, and that narrows the material list before acoustics is discussed.
The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.
The failure we design against here is seasonal movement in timber and winter damp in unheated stock.
On a Los Angeles 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 Los Angeles job
A mix room or ADR stage either isolates or it does not. There is no partial credit, which is why the shell gets designed before any fabric is chosen.
05 / Getting it there
How material reaches a Los Angeles site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Long Beach or Los Angeles, then a short road run |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Long Beach |
| 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 Long Beach or Los Angeles, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Los Angeles projects
What makes hospital and healthcare acoustics different in Los Angeles?
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. A mix room or ADR stage either isolates or it does not. There is no partial credit, which is why the shell gets designed before any fabric is chosen.
Where should the budget go first on a Los Angeles 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 Los Angeles?
No. We manufacture in India and supply into Los Angeles. 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 Los Angeles site?
ships from: Palwal, Haryana, India, arrives at: Long Beach or Los Angeles, then a short road run, 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
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.
