Recording studio acoustics and soundproofing in Mumbai
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. The deepest film, dubbing and music production base in the country, with rooms built inside commercial and residential buildings under real neighbour constraints.
- 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.

What you are buying, and what it fixes in Mumbai
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.
The deepest film, dubbing and music production base in the country, with rooms built inside commercial and residential buildings under real neighbour constraints.
Work reaching us from Mumbai is mostly recording studios, offices, flats and redevelopment towers, restaurants, clinics, schools.
- Every centimetre is paid for At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
- The studio capital More recording and dubbing rooms per square kilometre than anywhere else we supply. They sit inside occupied buildings, so isolation comes before tuning, always.
- Monsoon damp defeats the wrong material PET felt does not absorb moisture, shed fibre or feed mould. Mineral products sag here within a couple of seasons.
- 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 Mumbai.
02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Mumbai, split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
Layer 2
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 Mumbai, auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Mumbai, schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
Track with a seal. Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
The Mumbai conditions that change the answer
- Every centimetre is paid for
At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
- The studio capital
More recording and dubbing rooms per square kilometre than anywhere else we supply. They sit inside occupied buildings, so isolation comes before tuning, always.
- Monsoon damp defeats the wrong material
PET felt does not absorb moisture, shed fibre or feed mould. Mineral products sag here within a couple of seasons.
- Redevelopment, built fast
Old buildings replaced by towers on tight programmes. Acoustic detail is easy to lose unless it is specified before the slab is poured.
- The housing stock
Towers and chawls side by side, in RC frame with tile floors. Redevelopment stock shares slabs and lift cores, and monsoon damp rules out anything that holds moisture.
- The studio and content scene
The deepest film, dubbing and music production base in the country, with rooms built inside commercial and residential buildings under real neighbour constraints.
04 / Room by room
What each space in a Mumbai project needs
-
Isolation
A measured background level, agreed before anything is bought. At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
- Acoustic foam and BassBloc, 1800 x 900 mm
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Soundproof curtains, 5.5 kg per sq m
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. More recording and dubbing rooms per square kilometre than anywhere else we supply. They sit inside occupied buildings, so isolation comes before tuning, always.
- Acoustic foam and BassBloc, 20 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Soundproof curtains, Up to 30 dB
-
Early reflections
Controlled at the mix position, and only there. PET felt does not absorb moisture, shed fibre or feed mould. Mineral products sag here within a couple of seasons.
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Acoustic panels, ASTM C423
- Soundproof curtains, 30
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 and durability
What the Mumbai climate rules in and rules out
Mumbai is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
Where a consultant is already engaged on a Mumbai project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Straight talk
The six errors that cost the most
-
Buying foam to solve an isolation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
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 Mumbai job
At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
05 / Logistics
Getting it to Mumbai, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three to four days |
| Dispatch | 2 to 4 working days |
| To site | three to four days |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly fourteen hundred kilometres, normally three to four days on a dedicated truck.
Questions from Mumbai projects
What makes recording studio acoustics and soundproofing different in Mumbai?
The deepest film, dubbing and music production base in the country, with rooms built inside commercial and residential buildings under real neighbour constraints. At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
Where should the budget go first on a Mumbai 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 Mumbai?
No. We manufacture in India and supply into Mumbai. 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 Mumbai site?
made at: Our own plant, Palwal, Haryana, reaches site in: three to four days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
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.
