Recording studio acoustics and soundproofing in Los Angeles
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. Home and project studios go into basements and converted garages with equipment budgets far ahead of the building. The room leaks to the floor above long before it sounds wrong inside.
- 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 / What it is
The product, described honestly, for a Los Angeles brief
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.
Home and project studios go into basements and converted garages with equipment budgets far ahead of the building. The room leaks to the floor above long before it sounds wrong inside.
Work reaching us from Los Angeles is mostly post production and mix rooms, stages, offices, light frame housing, restaurants, schools.
- 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.
- 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.
- Designed to move Seismic detailing means junctions that must stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- 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 Los Angeles.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Acoustic foam and BassBloc
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing. 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.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
-
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.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
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.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
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
- 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.
- 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.
- 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.
- The housing stock
American homes are timber frame with gypsum board on both faces, so a party wall or a basement ceiling has almost no mass. Adding a second leaf with a limp membrane between does more than any amount of surface treatment.
- The studio and content scene
Home and project studios go into basements and converted garages with equipment budgets far ahead of the building. The room leaks to the floor above long before it sounds wrong inside.
04 / Room by room
What each space in a Los Angeles project needs
-
Isolation
A measured background level, agreed before anything is bought. Housing here is gypsum on studs behind stucco, which passes low frequency far more easily than masonry. Mass and decoupling do the work.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- 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. 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.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- 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. Seismic detailing means junctions that must stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Soundproof curtains, 30
For a Los Angeles interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
The Los Angeles climate decides the material list
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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Before you buy
Six mistakes that turn into a second fit-out
-
Buying foam to solve an isolation problem
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating the room before the shell is isolated
Small on the drawing, expensive on site, and almost always found after handover.
-
Killing the room completely and calling it controlled
More absorption is not better absorption. Past the target the room goes flat and people raise their voices to compensate.
-
Treating it as a generic Los Angeles job
Housing here is gypsum on studs behind stucco, which passes low frequency far more easily than masonry. Mass and decoupling do the work.
05 / Route to site
Getting it to Los Angeles, with real dates
| 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 recording studio acoustics and soundproofing different in Los Angeles?
Home and project studios go into basements and converted garages with equipment budgets far ahead of the building. The room leaks to the floor above long before it sounds wrong inside. 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?
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 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?
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.
