Recording studio acoustics and soundproofing in Delhi
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, barsatis and back rooms with neighbours on every side and a generator in the lane.
- 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 this is, and what it changes in a Delhi 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.
Studios go into basements, barsatis and back rooms with neighbours on every side and a generator in the lane.
Work reaching us from Delhi is mostly offices, studios, banquet halls, clinics, schools, home theatres, restaurants, showrooms.
- We can come and look Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
- Old walls and new towers Lutyens bungalows, 1970s DDA flats and glass towers all fail differently. We ask what the wall actually is before quoting anything.
- Traffic and generators get in On most Delhi sites the noise arrives through windows, shafts and gaps rather than through the wall itself. Fixing the weakest path first saves money.
- 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 Delhi.
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 Delhi, diesel generator sets, split unit banks and VRF outdoor units sit on terraces and in shafts close to bedrooms and offices.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
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 Delhi, 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 Delhi, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
Double layer at a doorway. Two curtains with an air gap where a single layer will not reach the target.
If you are specifying for a Delhi project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What we see driving Delhi briefs
- We can come and look
Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
- Old walls and new towers
Lutyens bungalows, 1970s DDA flats and glass towers all fail differently. We ask what the wall actually is before quoting anything.
- Traffic and generators get in
On most Delhi sites the noise arrives through windows, shafts and gaps rather than through the wall itself. Fixing the weakest path first saves money.
- Same day from the plant
Ninety kilometres of road. Low freight cost, next-day samples, and a damaged sheet replaced without a two-week wait.
- The housing stock
Builder flats, barsatis and independent houses in RC frame with brick infill, stacked floor by floor for separate households with no isolation in the slab.
- The studio and content scene
Studios go into basements, barsatis and back rooms with neighbours on every side and a generator in the lane.
04 / Room by room
Where the money goes on a Delhi project
-
Isolation
A measured background level, agreed before anything is bought. Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
- 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. Lutyens bungalows, 1970s DDA flats and glass towers all fail differently. We ask what the wall actually is before quoting anything.
- 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. On most Delhi sites the noise arrives through windows, shafts and gaps rather than through the wall itself. Fixing the weakest path first saves money.
- 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 Delhi 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
What the Delhi climate rules in and rules out
Delhi is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
Where a consultant is already engaged on a Delhi project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
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
This is the one that comes back as a second fit-out rather than a snag.
-
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 Delhi job
Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
05 / Supply
What the route into Delhi actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | same or next day |
| Dispatch | 2 to 4 working days |
| To site | same or next day |
| 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.
Same day or next day by road from Palwal, about ninety kilometres south. Small consignments on a shared vehicle, full loads on a dedicated truck.
Questions from Delhi projects
What makes recording studio acoustics and soundproofing different in Delhi?
Studios go into basements, barsatis and back rooms with neighbours on every side and a generator in the lane. Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
Where should the budget go first on a Delhi 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 Delhi?
No. We manufacture in India and supply into Delhi. 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 Delhi site?
made at: Our own plant, Palwal, Haryana, reaches site in: same or next day, 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.
