Auditorium acoustics and soundproofing in Silchar
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 / The material
What this material is and where it earns its place in Silchar
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 Silchar is mostly colleges and schools, hospitals, government buildings, hotels, assembly halls, offices.
- A long route, planned properly Five days and a hill leg at the end. We brace and wrap for the journey and confirm dates before dispatch.
- High humidity most of the year PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Institutional rooms Lecture halls and assembly spaces in concrete and tile that defeat the speaker.
- 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 Silchar.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Silchar, 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 Silchar, 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 felt backing. The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Silchar, schools and colleges are naturally ventilated with open corridors and large class sizes.
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.
If you are specifying for a Silchar project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / Local conditions
What the buildings in Silchar do to the specification
- A long route, planned properly
Five days and a hill leg at the end. We brace and wrap for the journey and confirm dates before dispatch.
- High humidity most of the year
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Institutional rooms
Lecture halls and assembly spaces in concrete and tile that defeat the speaker.
- Seismic zone
Buildings are designed to move, so a build-up must not stiffen across a movement joint.
- 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 and colleges are naturally ventilated with open corridors and large class sizes.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Five days and a hill leg at the end. We brace and wrap for the journey and confirm dates before dispatch.
- 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. PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- 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. Lecture halls and assembly spaces in concrete and tile that defeat the speaker.
- 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
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 Silchar, before acoustics is discussed
Silchar 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.
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
Six mistakes that turn into a second fit-out
-
Absorbing the whole room and losing the back rows
This is the one that comes back as a second fit-out rather than a snag.
-
Adding speakers to fix a reverberation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
Ignoring the rear wall because it is behind the audience
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Silchar job
Five days and a hill leg at the end. We brace and wrap for the journey and confirm dates before dispatch.
05 / Route to site
Supply into Silchar, 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 twenty one hundred kilometres, normally five days on a dedicated truck. The last leg is hill road and we plan for it.
Questions from Silchar projects
What makes auditorium acoustics and soundproofing different in Silchar?
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. Five days and a hill leg at the end. We brace and wrap for the journey and confirm dates before dispatch.
Where should the budget go first on a Silchar 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 Silchar?
No. We manufacture in India and supply into Silchar. 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 Silchar 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.
