School and classroom acoustics in Rishikesh
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. Classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room 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.

01 / What it is
The product, described honestly, for a Rishikesh 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.
Classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
Work reaching us from Rishikesh is mostly meditation and yoga halls, retreat accommodation, ashrams, hotels, cafes, clinics.
- River and road outside Traffic and river noise reach rooms through openings and glazing, which is a facade question before it is a wall question.
- Quiet is the product Guests come specifically for stillness, so a corridor or neighbour audible in a retreat room is a failure of the offering rather than a comfort issue.
- Halls for practice and teaching Rooms used for chanting, instruction and silence in turn. The design has to serve a very wide range of levels.
- 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 Rishikesh.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Rishikesh, hotel plant, boilers and generator sets close to guest rooms in compact hillside buildings.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 2
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 Rishikesh, hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Rishikesh, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
We would rather argue about the build-up at design stage than on site. See how we support architects.

What decides the build-up in Rishikesh
- River and road outside
Traffic and river noise reach rooms through openings and glazing, which is a facade question before it is a wall question.
- Quiet is the product
Guests come specifically for stillness, so a corridor or neighbour audible in a retreat room is a failure of the offering rather than a comfort issue.
- Halls for practice and teaching
Rooms used for chanting, instruction and silence in turn. The design has to serve a very wide range of levels.
- Next day from the plant
A short run, so samples arrive quickly and freight stays low.
- Assembly and performance rooms
Hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
04 / Room by room
Room by room, on a typical Rishikesh job
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Traffic and river noise reach rooms through openings and glazing, which is a facade question before it is a wall question.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- 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. Guests come specifically for stillness, so a corridor or neighbour audible in a retreat room is a failure of the offering rather than a comfort issue.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- 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. Rooms used for chanting, instruction and silence in turn. The design has to serve a very wide range of levels.
- PET felt acoustic panels, 4 to 24 mm
- Acoustic panels, ASTM C423
- Acoustic carpet and rugs, 64 sq ft per pack
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 and durability
Durability in Rishikesh, before acoustics is discussed
Rishikesh 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.
Where a consultant is already engaged on a Rishikesh project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

The six errors that cost the most
-
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
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 Rishikesh job
Traffic and river noise reach rooms through openings and glazing, which is a facade question before it is a wall question.
05 / Logistics
What the route into Rishikesh actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | next day |
| Dispatch | 2 to 4 working days |
| To site | next 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 three hundred kilometres, normally next day on a dedicated truck.
Questions from Rishikesh projects
What makes school and classroom acoustics different in Rishikesh?
Classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them. Guests come specifically for stillness, so a corridor or neighbour audible in a retreat room is a failure of the offering rather than a comfort issue.
Where should the budget go first on a Rishikesh 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 Rishikesh?
No. We manufacture in India and supply into Rishikesh. 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 Rishikesh site?
made at: Our own plant, Palwal, Haryana, reaches site in: next 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
Drawings in, BOQ and a delivered date out
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.
