Recording studio acoustics and soundproofing in Chennai
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. Studios go into basements, terrace rooms and back rooms with neighbours on every side and a generator somewhere in the lane. Isolating from the building has to come before treating the room.
- 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 material
What you are buying, and what it fixes in Chennai
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.
Studios go into basements, terrace rooms and back rooms with neighbours on every side and a generator somewhere in the lane. Isolating from the building has to come before treating the room.
Work reaching us from Chennai is mostly IT corridor offices, automotive plants, recording and dubbing rooms, hospitals, schools, hotels.
- Salt air and humidity PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
- Automotive plants Presses, conveyors and test rooms where the answer is enclosure and mass rather than absorption on a far wall.
- Dubbing and recording rooms A long established film sound industry, mostly in rooms inside occupied buildings. Isolation first, tuning second.
- 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 Chennai.
02 / The build-up
The stack, in the order it is installed
-
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 Chennai, 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 Chennai, kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Chennai, very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
Full height with return. Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
For a Chennai practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

What the buildings in Chennai do to the specification
- Salt air and humidity
PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
- Automotive plants
Presses, conveyors and test rooms where the answer is enclosure and mass rather than absorption on a far wall.
- Dubbing and recording rooms
A long established film sound industry, mostly in rooms inside occupied buildings. Isolation first, tuning second.
- Sealed against the heat
Rooms stay closed and conditioned for most of the year, so sound builds up inside instead of leaking away.
- The housing stock
RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.
- The studio and content scene
Studios go into basements, terrace rooms and back rooms with neighbours on every side and a generator somewhere in the lane. Isolating from the building has to come before treating the room.
04 / Room by room
What each space in a Chennai project needs
-
Isolation
A measured background level, agreed before anything is bought. PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
- 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
- Soundproof curtains, 5.5 kg per sq m
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Presses, conveyors and test rooms where the answer is enclosure and mass rather than absorption on a far wall.
- 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
- Soundproof curtains, Up to 30 dB
-
Early reflections
Controlled at the mix position, and only there. A long established film sound industry, mostly in rooms inside occupied buildings. Isolation first, tuning second.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic panels, ASTM C423
- Soundproof curtains, 30
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Conditions
What the Chennai climate rules in and rules out
Chennai 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 Chennai job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

Where this kind of project usually fails
-
Buying foam to solve an isolation problem
This is the one that comes back as a second fit-out rather than a snag.
-
Treating the room before the shell is isolated
It sounds like a small detail until the room is finished and the complaint arrives.
-
Killing the room completely and calling it controlled
We would rather calculate the area and sell you less of it than line every surface and call it thorough.
-
Treating it as a generic Chennai job
PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
05 / Getting it there
What the route into Chennai actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | five 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 twenty two hundred kilometres, normally five days on a dedicated truck.
Questions from Chennai projects
What makes recording studio acoustics and soundproofing different in Chennai?
Studios go into basements, terrace rooms and back rooms with neighbours on every side and a generator somewhere in the lane. Isolating from the building has to come before treating the room. PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
Where should the budget go first on a Chennai 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 Chennai?
No. We manufacture in India and supply into Chennai. 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 Chennai site?
made at: Our own plant, Palwal, Haryana, reaches site in: five 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.
