Auditorium acoustics and soundproofing in Kanpur
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 / What it is
The product, described honestly, for a Kanpur brief
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 Kanpur is mostly leather and textile units, engineering workshops, offices, colleges, hospitals, banquet halls.
- Machinery, long shifts Continuous machine noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the hall.
- Industry beside housing Units sit close to homes, so noise leaving the building matters as much as noise inside it. Two different treatments.
- Older building stock Solid masonry with high ceilings, which holds sound and offers little in the way of a cavity to work with.
- 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 Kanpur.
02 / The build-up
What goes where, from the structure in
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Kanpur, 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.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Kanpur, banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Kanpur, 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.
If you are specifying for a Kanpur project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.

What decides the build-up in Kanpur
- Machinery, long shifts
Continuous machine noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the hall.
- Industry beside housing
Units sit close to homes, so noise leaving the building matters as much as noise inside it. Two different treatments.
- Older building stock
Solid masonry with high ceilings, which holds sound and offers little in the way of a cavity to work with.
- Next day from the plant
A short run, so freight stays cheap and samples reach you quickly.
- 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.
04 / Room by room
What each space in a Kanpur project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Continuous machine noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the hall.
- Wood wool acoustic panels, 1200 x 600 mm
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Units sit close to homes, so noise leaving the building matters as much as noise inside it. Two different treatments.
- Wood wool acoustic panels, 20 mm
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
Rear wall
The single worst surface in most halls, and the first one to treat. Solid masonry with high ceilings, which holds sound and offers little in the way of a cavity to work with.
- Wood wool acoustic panels, 400 kg per cubic metre
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Ceiling baffles and clouds, ASTM C423
For a Kanpur interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate
Why the climate in Kanpur changes the material, not the target
Kanpur 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.
On a Kanpur 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
-
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Kanpur job
Continuous machine noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the hall.
05 / Supply
How material reaches a Kanpur site
| 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 five hundred kilometres, normally next day on a dedicated truck.
Questions from Kanpur projects
What makes auditorium acoustics and soundproofing different in Kanpur?
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night. Continuous machine noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the hall.
Where should the budget go first on a Kanpur 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 Kanpur?
No. We manufacture in India and supply into Kanpur. 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 Kanpur 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.
