School and classroom acoustics in Kanpur
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. Large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

The material, and what it actually does on a Kanpur job
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
Large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
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.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school 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.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Kanpur, banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 3
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 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.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
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.
03 / Local conditions
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
Where the money goes on a Kanpur project
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. 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
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. 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
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. 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
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- 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
Durability in Kanpur, before acoustics is discussed
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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
Panels at child height where they get damaged
This is the one that comes back as a second fit-out rather than a snag.
-
Treating one classroom and leaving the corridor
Small on the drawing, expensive on site, and almost always found after handover.
-
Choosing a product that cannot take a football
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
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
What the route into Kanpur 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 five hundred kilometres, normally next day on a dedicated truck.
Questions from Kanpur projects
What makes school and classroom acoustics different 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. 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?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
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?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
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 a plan and a section, get a real build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
