Modern school classroom with felt acoustic panels on walls

For projects in Shillong

School and classroom acoustics in Shillong

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 have hard floors, bare walls and long corridors that amplify noise, with music a strong part of school life.

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 Shillong 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 have hard floors, bare walls and long corridors that amplify noise, with music a strong part of school life.

Work reaching us from Shillong is mostly practice and performance rooms, schools and colleges, hotels, churches and halls, clinics, offices.

  • Timber and light construction Hill building is often light, which passes low frequency easily. Mass and decoupling do the work.
  • Hill roads on the last leg The final stretch is steep and rough. We pack for that rather than for a straight highway run.
  • Rain on the roof Metal roofing under extreme rainfall turns a downpour into a noise source that stops a lesson or a recording. It is worth designing for rather than discovering.
  • 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 Shillong.

02 / The build-up

The build-up, layer by layer

  1. PET acoustic felt wall panels in office interior

    Layer 1

    PET felt acoustic panels

    A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Shillong, 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.

  2. Acoustic hanging ceiling baffles in a large open space

    Layer 2

    Ceiling baffles and clouds

    PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Shillong, 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.

  3. Acoustic carpet tiles and rugs on a modern floor

    Layer 3

    Acoustic carpet and rugs

    A tile carpet with a dense polyester face on a felt backing. In Shillong, schools have hard floors, bare walls and long corridors that amplify noise, with music a strong part of school life.

    Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.

For a Shillong 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 Shillong do to the specification

  • Timber and light construction

    Hill building is often light, which passes low frequency easily. Mass and decoupling do the work.

  • Hill roads on the last leg

    The final stretch is steep and rough. We pack for that rather than for a straight highway run.

  • Rain on the roof

    Metal roofing under extreme rainfall turns a downpour into a noise source that stops a lesson or a recording. It is worth designing for rather than discovering.

  • A music city

    Practice rooms, choirs and performance spaces in ordinary buildings. Isolation from neighbours is what keeps them usable.

  • 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 have hard floors, bare walls and long corridors that amplify noise, with music a strong part of school life.

04 / Room by room

Where the money goes on a Shillong project

  • Classroom walls treated with felt acoustic panels

    Classroom RT

    A number, set against room volume, achieved mostly at the ceiling. Hill building is often light, which passes low frequency easily. Mass and decoupling do the work.

  • Library with felt acoustic panels

    Corridor spill

    Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. The final stretch is steep and rough. We pack for that rather than for a straight highway run.

  • School corridor treated with felt acoustic panels

    Halls and gyms

    Dual use rooms carrying speech, music and sport, where durability decides the product. Metal roofing under extreme rainfall turns a downpour into a noise source that stops a lesson or a recording. It is worth designing for rather than discovering.

If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.

04 / Conditions

The Shillong climate decides the material list

Shillong 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.

Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.

06 / Before you buy

The six errors that cost the most

  • 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

    Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.

  • Treating it as a generic Shillong job

    Hill building is often light, which passes low frequency easily. Mass and decoupling do the work.

SupportDrawings, 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 two thousand kilometres, normally five days on a dedicated truck. The final hill leg is planned into the schedule.

FAQ

Questions from Shillong projects

What makes school and classroom acoustics different in Shillong?

Schools have hard floors, bare walls and long corridors that amplify noise, with music a strong part of school life. Metal roofing under extreme rainfall turns a downpour into a noise source that stops a lesson or a recording. It is worth designing for rather than discovering.

Where should the budget go first on a Shillong 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 Shillong?

No. We manufacture in India and supply into Shillong. 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 Shillong site?

made at: Our own plant, Palwal, Haryana, reaches site in: five 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

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.
