Auditorium acoustics and soundproofing in Shillong
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem. 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.
- Reverberation time
- Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
- Early reflections
- Shaped surfaces that send energy to the rear seats rather than absorbing everything.
- Rear wall
- The single worst surface in most halls, and the first one to treat.

01 / What it is
The product, described honestly, for a Shillong brief
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem.
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.
Work reaching us from Shillong is mostly practice and performance rooms, schools and colleges, hotels, churches and halls, clinics, offices.
- 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.
- Timber and light construction Hill building is often light, which passes low frequency easily. Mass and decoupling do the work.
- Reverberation time Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for auditorium acoustics are on the main product page. This page covers what that means for a project in Shillong.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. 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.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. 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.
Slats on a cavity. Backing plus an air gap behind moves absorption lower, which matters in music rooms.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Shillong, schools have hard floors, bare walls and long corridors that amplify noise, with music a strong part of school life.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
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 decides the build-up in Shillong
- 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.
- 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.
- 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.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. 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.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Practice rooms, choirs and performance spaces in ordinary buildings. Isolation from neighbours is what keeps them usable.
- Wood wool acoustic panels, 20 mm
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Hill building is often light, which passes low frequency easily. Mass and decoupling do the work.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- Acoustic carpet and rugs, 64 sq ft per pack
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 / Durability
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
What we watch go wrong on jobs like this
-
Absorbing the whole room and losing the back rows
Small on the drawing, expensive on site, and almost always found after handover.
-
Adding speakers to fix a reverberation problem
It sounds like a small detail until the room is finished and the complaint arrives.
-
Ignoring the rear wall because it is behind the audience
It sounds like a small detail until the room is finished and the complaint arrives.

Treating it as a generic Shillong job
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.
05 / Route to site
Supply into Shillong, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | five 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 two thousand kilometres, normally five days on a dedicated truck. The final hill leg is planned into the schedule.
Questions from Shillong projects
What makes auditorium acoustics and soundproofing different 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. 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?
Reverberation time. Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Early reflections. Shaped surfaces that send energy to the rear seats rather than absorbing everything.
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?
Absorbing the whole room and losing the back rows. Adding speakers to fix a reverberation problem.
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
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.
