Auditorium acoustics and soundproofing in Varanasi
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem. Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
- Reverberation time
- Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
- Early reflections
- Shaped surfaces that send energy to the rear seats rather than absorbing everything.
- Rear wall
- The single worst surface in most halls, and the first one to treat.

01 / The product
What this material is and where it earns its place in Varanasi
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem.
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
Work reaching us from Varanasi is mostly hotels and guest houses, assembly halls, colleges, hospitals, restaurants, offices.
- Access decides the delivery Narrow lanes and no vehicle access to many properties. We size and split pallets to what can be carried, which saves a wasted delivery.
- Guest rooms in old buildings Thick masonry but thin internal partitions, and corridors that carry everything. Door and partition detailing does the work.
- Assembly and event spaces Large halls where speech has to survive a crowd, usually in hard masonry with high ceilings.
- Reverberation time Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for auditorium acoustics are on the main product page. This page covers what that means for a project in Varanasi.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Varanasi, 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.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Varanasi, banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
Feature wall only. Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Varanasi, large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What decides the build-up in Varanasi
- Access decides the delivery
Narrow lanes and no vehicle access to many properties. We size and split pallets to what can be carried, which saves a wasted delivery.
- Guest rooms in old buildings
Thick masonry but thin internal partitions, and corridors that carry everything. Door and partition detailing does the work.
- Assembly and event spaces
Large halls where speech has to survive a crowd, usually in hard masonry with high ceilings.
- Humid through the season
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Assembly and performance rooms
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
- School and campus buildings
Large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Narrow lanes and no vehicle access to many properties. We size and split pallets to what can be carried, which saves a wasted delivery.
- Wooden slat acoustic panels, MDF, FR MDF, HDF or HDHMR
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Thick masonry but thin internal partitions, and corridors that carry everything. Door and partition detailing does the work.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- PET felt acoustic panels, 4 to 24 mm
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Large halls where speech has to survive a crowd, usually in hard masonry with high ceilings.
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
What the Varanasi climate rules in and rules out
Varanasi 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.
06 / Straight talk
What we watch go wrong on jobs like this
-
Absorbing the whole room and losing the back rows
It sounds like a small detail until the room is finished and the complaint arrives.
-
Adding speakers to fix a reverberation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
Ignoring the rear wall because it is behind the audience
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Varanasi job
Narrow lanes and no vehicle access to many properties. We size and split pallets to what can be carried, which saves a wasted delivery.
05 / Route to site
What the route into Varanasi actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a day |
| Dispatch | 2 to 4 working days |
| To site | a 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.
By road from Palwal, roughly eight hundred kilometres, normally next day on a dedicated truck. Delivery into the old city needs planning and we will ask about access.
Questions from Varanasi projects
What makes auditorium acoustics and soundproofing different in Varanasi?
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night. Narrow lanes and no vehicle access to many properties. We size and split pallets to what can be carried, which saves a wasted delivery.
Where should the budget go first on a Varanasi project?
Reverberation time. Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Early reflections. Shaped surfaces that send energy to the rear seats rather than absorbing everything.
Do you have an office or installation team in Varanasi?
No. We manufacture in India and supply into Varanasi. 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 Varanasi site?
made at: Our own plant, Palwal, Haryana, reaches site in: a 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?
Absorbing the whole room and losing the back rows. Adding speakers to fix a reverberation problem.
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
Send the drawings, get a straight answer
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.
