Cinema and multiplex soundproofing in Boston
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes. Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
- Screen to screen
- Independent construction between auditoria, with services broken at the line.
- In room response
- Heavy absorption on side and rear walls so the mix is heard as intended.
- Plant and projection
- Equipment noise into the auditorium, treated at source.

01 / The material
What this material is and where it earns its place in Boston
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes.
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 Boston is mostly universities and labs, teaching hospitals, offices, triple-decker housing, studios, schools.
- Institutions specify properly University and hospital work arrives with a consultant and a written target. Send us the specification and we will say where our material sits against it, in writing.
- Labs and equipment rooms Fume hoods, chillers and equipment run constantly next to rooms where people have to concentrate. That is a plant isolation problem before it is a room treatment problem.
- Old brick and triple-deckers Boston housing stock is old, wooden inside and stacked. Floors between units pass footfall easily, and a resilient layer under the finish is what fixes it.
- Screen to screen Independent construction between auditoria, with services broken at the line.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for cinema soundproofing are on the main product page. This page covers what that means for a project in Boston.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Boston, 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.
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 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 Boston, 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
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Boston, 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.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What we see driving Boston briefs
- Institutions specify properly
University and hospital work arrives with a consultant and a written target. Send us the specification and we will say where our material sits against it, in writing.
- Labs and equipment rooms
Fume hoods, chillers and equipment run constantly next to rooms where people have to concentrate. That is a plant isolation problem before it is a room treatment problem.
- Old brick and triple-deckers
Boston housing stock is old, wooden inside and stacked. Floors between units pass footfall easily, and a resilient layer under the finish is what fixes it.
- Sealed against hard winters
Buildings close up for months and mechanical systems run hard. Noise stops escaping and starts accumulating inside.
- 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.
04 / Room by room
What each space in a Boston project needs
-
Screen to screen
Independent construction between auditoria, with services broken at the line. University and hospital work arrives with a consultant and a written target. Send us the specification and we will say where our material sits against it, in writing.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- PET felt acoustic panels, 4 to 24 mm
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Fume hoods, chillers and equipment run constantly next to rooms where people have to concentrate. That is a plant isolation problem before it is a room treatment problem.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. Boston housing stock is old, wooden inside and stacked. Floors between units pass footfall easily, and a resilient layer under the finish is what fixes it.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic panels, ASTM C423
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
For a Boston interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Conditions
Durability in Boston, before acoustics is discussed
Boston 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.
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 / Worth knowing
The six errors that cost the most
-
A shared service void running across the wall line
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating the auditorium to fix bleed from the next screen
It sounds like a small detail until the room is finished and the complaint arrives.
-
Doors and lobbies specified late and undersized
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic Boston job
University and hospital work arrives with a consultant and a written target. Send us the specification and we will say where our material sits against it, in writing.
05 / Getting it there
How material reaches a Boston site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Boston or a nearby East Coast port, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into the East Coast |
| 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 Boston or a nearby East Coast port, then road to site. Air freight for samples, approvals and urgent quantities.
Questions from Boston projects
What makes cinema and multiplex soundproofing different in Boston?
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both. University and hospital work arrives with a consultant and a written target. Send us the specification and we will say where our material sits against it, in writing.
Where should the budget go first on a Boston project?
Screen to screen. Independent construction between auditoria, with services broken at the line. In room response. Heavy absorption on side and rear walls so the mix is heard as intended.
Do you have an office or installation team in Boston?
No. We manufacture in India and supply into Boston. 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 Boston site?
ships from: Palwal, Haryana, India, arrives at: Boston or a nearby East Coast port, then road to site, 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?
A shared service void running across the wall line. Treating the auditorium to fix bleed from the next screen.
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
Drawings in, BOQ and a delivered date out
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.
