Venue and restaurant acoustics in Delhi
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other. 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.
- Containment
- Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
- Table level comfort
- Absorption at the ceiling so guests stop raising their voices at each other.
- Entrance and service
- Doors, lobbies and extract paths, which is where most of the leakage actually is.

01 / The product
What you are buying, and what it fixes in Delhi
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other.
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.
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.
- Containment Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for venue soundproofing are on the main product page. This page covers what that means for a project in Delhi.

02 / The build-up
How the layers stack, from the structure inwards
-
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.
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
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 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.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
Wooden slat acoustic panels
Timber slats on an acoustic backing. 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.
Slats on felt backing. The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
Architects working in Delhi usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

What decides the build-up in Delhi
- 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.
- Assembly and performance rooms
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.

Absorption at the ceiling so guests stop raising their voices at each other. Lutyens bungalows, 1970s DDA flats and glass towers all fail differently. We ask what the wall actually is before quoting anything.

Entrance and service
Doors, lobbies and extract paths, which is where most of the leakage actually is. 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.

- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Wooden slat acoustic panels, 96 sq ft per unit
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 / Durability
Why the climate in Delhi changes the material, not the target
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.
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.

Six mistakes that turn into a second fit-out
-
Panels on the wall as a neighbour noise solution
This is the one that comes back as a second fit-out rather than a snag.
-
A lobby with both doors able to open at once
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Extract ducting that bypasses every wall you built
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.

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 / Logistics
How material reaches a Delhi site
| 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 venue and restaurant acoustics different 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. 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?
Containment. Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Table level comfort. Absorption at the ceiling so guests stop raising their voices at each other.
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?
Panels on the wall as a neighbour noise solution. A lobby with both doors able to open at once.
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
Tell us the room, we will tell you the build-up
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
