Auditorium acoustics and soundproofing in Dibrugarh
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 Dibrugarh 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 Dibrugarh is mostly tea processing units, energy sector offices, hospitals, colleges, hotels, assembly halls.
- Processing machinery Driers, sorters and fans running continuously in humid buildings. Enclosure at the source is the reliable answer.
- Very high humidity PET felt does not absorb moisture, shed fibre or feed mould, which matters in a climate where mineral products fail quickly.
- A long supply route Five days by road, confirmed before dispatch, and packed for the journey rather than for a short transfer.
- 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 Dibrugarh.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Dibrugarh, 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.
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 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Dibrugarh, 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.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Dibrugarh, schools and colleges are naturally ventilated with open corridors and large class sizes.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What the buildings in Dibrugarh do to the specification
- Processing machinery
Driers, sorters and fans running continuously in humid buildings. Enclosure at the source is the reliable answer.
- Very high humidity
PET felt does not absorb moisture, shed fibre or feed mould, which matters in a climate where mineral products fail quickly.
- A long supply route
Five days by road, confirmed before dispatch, and packed for the journey rather than for a short transfer.
- Seismic and flood prone
Buildings are designed to move and often raised. A build-up must respect both rather than fight them.
- 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.

Rear wall
The single worst surface in most halls, and the first one to treat. Five days by road, confirmed before dispatch, and packed for the journey rather than for a short transfer.
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm

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 Dibrugarh, before acoustics is discussed
Dibrugarh 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.
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
-
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
Small on the drawing, expensive on site, and almost always found after handover.
-
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 Dibrugarh job
Driers, sorters and fans running continuously in humid buildings. Enclosure at the source is the reliable answer.
05 / Logistics
What the route into Dibrugarh actually looks like
| 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 two hundred kilometres, normally five days on a dedicated truck.
Questions from Dibrugarh projects
What makes auditorium acoustics and soundproofing different in Dibrugarh?
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. Driers, sorters and fans running continuously in humid buildings. Enclosure at the source is the reliable answer.
Where should the budget go first on a Dibrugarh 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 Dibrugarh?
No. We manufacture in India and supply into Dibrugarh. 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 Dibrugarh 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
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
