Recording studio acoustics and soundproofing in Nagpur
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.

01 / The product
What this is, and what it changes in a Nagpur room
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 Nagpur is mostly warehouses and processing units, colleges, hospitals, offices, auditoriums, hotels.
- Warehouse volumes Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
- Processing machinery Continuous plant noise close to occupied areas. Enclosure at the source is the reliable answer.
- Institutional buildings Colleges and hospitals in concrete and tile, where lecture rooms defeat the speaker and consult rooms offer no privacy.
- 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 Nagpur.
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 Nagpur, 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.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
-
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 Nagpur, 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.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Nagpur, schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
Double layer at a doorway. Two curtains with an air gap where a single layer will not reach the target.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
What the buildings in Nagpur do to the specification
- Warehouse volumes
Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
- Processing machinery
Continuous plant noise close to occupied areas. Enclosure at the source is the reliable answer.
- Institutional buildings
Colleges and hospitals in concrete and tile, where lecture rooms defeat the speaker and consult rooms offer no privacy.
- Dry heat
PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- 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.

Where the money goes on a Nagpur project
-
Isolation
A measured background level, agreed before anything is bought. Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
- Acoustic foam and BassBloc, 1800 x 900 mm
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Continuous plant noise close to occupied areas. Enclosure at the source is the reliable answer.
- Acoustic foam and BassBloc, 20 mm
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
-
Early reflections
Controlled at the mix position, and only there. Colleges and hospitals in concrete and tile, where lecture rooms defeat the speaker and consult rooms offer no privacy.
- Acoustic foam and BassBloc, 100 kg per cubic metre
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate
The Nagpur climate decides the material list
Nagpur 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.
On a Nagpur job with a consultant involved, our part is material that matches the submitted data. See 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
A room can be over-treated. Past the target it stops sounding controlled and starts sounding dead, and you paid for that.
-
Treating it as a generic Nagpur job
Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
05 / Supply
How material reaches a Nagpur site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two to three days |
| Dispatch | 2 to 4 working days |
| To site | two to three 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 eleven hundred kilometres, normally two to three days on a dedicated truck.
Questions from Nagpur projects
What makes recording studio acoustics and soundproofing different in Nagpur?
The deepest film, dubbing and music production base in the country, with rooms built inside commercial and residential buildings under real neighbour constraints. Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
Where should the budget go first on a Nagpur 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 Nagpur?
No. We manufacture in India and supply into Nagpur. 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 Nagpur site?
made at: Our own plant, Palwal, Haryana, reaches site in: two to three 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.
Next step
Drawings in, BOQ and a delivered date out
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
