School and classroom acoustics in Pune
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. Schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
- 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.

01 / What it is
The material, and what it actually does on a Pune 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.
Schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
Work reaching us from Pune is mostly automotive and engineering plants, townships and apartment towers, IT offices, colleges, clinics.
- Machinery, not conversation Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
- New townships, repeated details The same separating wall across hundreds of flats. Getting it right on the drawing is far cheaper than fixing it after possession.
- Education and test rooms Colleges and engineering centres with rooms that need a genuinely low background before measurement means anything.
- 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 Pune.
02 / The build-up
The build-up, layer by layer
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Pune, 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.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Pune, 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.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Pune, schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
For a Pune practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

What we see driving Pune briefs
- Machinery, not conversation
Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
- New townships, repeated details
The same separating wall across hundreds of flats. Getting it right on the drawing is far cheaper than fixing it after possession.
- Education and test rooms
Colleges and engineering centres with rooms that need a genuinely low background before measurement means anything.
- Monsoon damp
PET felt does not absorb moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- 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.
- School and campus buildings
Schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.

Where the money goes on a Pune project
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
- Wood wool acoustic panels, 1200 x 600 mm
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- 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. The same separating wall across hundreds of flats. Getting it right on the drawing is far cheaper than fixing it after possession.
- Wood wool acoustic panels, 20 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Colleges and engineering centres with rooms that need a genuinely low background before measurement means anything.
- Wood wool acoustic panels, 400 kg per cubic metre
- Acoustic panels, ASTM C423
- Acoustic carpet and rugs, 64 sq ft per pack
For a Pune interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Conditions
Why the climate in Pune changes the material, not the target
Pune is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
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 / Before you buy
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Pune job
Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
05 / Getting it there
How material reaches a Pune site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three to four days |
| Dispatch | 2 to 4 working days |
| To site | three to four days |
| 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 fourteen hundred kilometres, normally three to four days on a dedicated truck.
Questions from Pune projects
What makes school and classroom acoustics different in Pune?
Schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces. Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
Where should the budget go first on a Pune 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 Pune?
No. We manufacture in India and supply into Pune. 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 Pune site?
made at: Our own plant, Palwal, Haryana, reaches site in: three to four days, 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
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.
