School and classroom acoustics in Indore
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 school and college campuses in concrete and tile with halls used for assembly and examinations.
- 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 product, described honestly, for a Indore brief
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 school and college campuses in concrete and tile with halls used for assembly and examinations.
Work reaching us from Indore is mostly colleges and schools, hospitals, offices, food processing units, auditoriums, hotels.
- New buildings, late decisions Concrete and tile put up quickly, with the acoustic problem discovered at handover. Early drawings are worth more than extra material later.
- Food processing plant Continuous machinery and packing lines close to occupied areas. Enclosure at the source rather than lining the hall.
- Teaching and assembly Large lecture rooms and halls where speech fails long before anyone calls the room echoey.
- 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 Indore.
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 Indore, 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
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Indore, 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.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Indore, large school and college campuses in concrete and tile with halls used for assembly and examinations.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
For a Indore practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

What the buildings in Indore do to the specification
- New buildings, late decisions
Concrete and tile put up quickly, with the acoustic problem discovered at handover. Early drawings are worth more than extra material later.
- Food processing plant
Continuous machinery and packing lines close to occupied areas. Enclosure at the source rather than lining the hall.
- Teaching and assembly
Large lecture rooms and halls where speech fails long before anyone calls the room echoey.
- Two days by road
A manageable run, so freight stays reasonable and samples arrive before the order is placed.
- 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
Large school and college campuses in concrete and tile with halls used for assembly and examinations.
04 / Room by room
Room by room, on a typical Indore job
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Concrete and tile put up quickly, with the acoustic problem discovered at handover. Early drawings are worth more than extra material later.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. Continuous machinery and packing lines close to occupied areas. Enclosure at the source rather than lining the hall.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- 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
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Large lecture rooms and halls where speech fails long before anyone calls the room echoey.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate
The Indore climate decides the material list
Indore 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 / Before you buy
Six mistakes that turn into a second fit-out
-
Panels at child height where they get damaged
It sounds like a small detail until the room is finished and the complaint arrives.
-
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
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 Indore job
Concrete and tile put up quickly, with the acoustic problem discovered at handover. Early drawings are worth more than extra material later.
05 / Logistics
Supply into Indore, start to site
| Made at | Our own plant, Palwal, Haryana |

| To site | two 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 nine hundred kilometres, normally two days on a dedicated truck.
Questions from Indore projects
What makes school and classroom acoustics different in Indore?
Large school and college campuses in concrete and tile with halls used for assembly and examinations. Concrete and tile put up quickly, with the acoustic problem discovered at handover. Early drawings are worth more than extra material later.
Where should the budget go first on a Indore 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 Indore?
No. We manufacture in India and supply into Indore. 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 Indore site?
made at: Our own plant, Palwal, Haryana, reaches site in: two 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 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.
