Auditorium acoustics and soundproofing in Bhubaneswar
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 Bhubaneswar
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 Bhubaneswar is mostly IT and institutional campuses, hospitals, colleges, auditoriums, hotels, offices.
- New campuses at scale The same classroom or office detail repeated across many blocks. Consistency across the order is where the value is.
- Coastal humidity and cyclones PET felt does not absorb moisture, rot or feed mould, which matters where mineral products sag within a couple of seasons.
- Teaching and assembly rooms Large halls in concrete and tile that defeat the speaker 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.
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 Bhubaneswar.
02 / The build-up
The build-up, layer by layer
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bhubaneswar, 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.
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.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bhubaneswar, 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.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Bhubaneswar, new university and school campuses in concrete and tile, with lecture halls and hostels repeating the same detail.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
Architects working in Bhubaneswar usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

What decides the build-up in Bhubaneswar
- New campuses at scale
The same classroom or office detail repeated across many blocks. Consistency across the order is where the value is.
- Coastal humidity and cyclones
PET felt does not absorb moisture, rot or feed mould, which matters where mineral products sag within a couple of seasons.
- Teaching and assembly rooms
Large halls in concrete and tile that defeat the speaker long before anyone calls the room echoey.
- Three to four days by road
A dedicated truck from Palwal, confirmed before dispatch, with samples sent ahead.
- 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
New university and school campuses in concrete and tile, with lecture halls and hostels repeating the same detail.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. The same classroom or office detail repeated across many blocks. Consistency across the order is where the value is.
- Wood wool acoustic panels, 1200 x 600 mm
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- 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 absorb moisture, rot or feed mould, which matters where mineral products sag within a couple of seasons.
- Wood wool acoustic panels, 20 mm
- PET felt acoustic panels, 4 to 24 mm
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Large halls in concrete and tile that defeat the speaker long before anyone calls the room echoey.
- Wood wool acoustic panels, 400 kg per cubic metre
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- 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 / Conditions
Durability in Bhubaneswar, before acoustics is discussed
Bhubaneswar 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.

What we watch go wrong on jobs like this
-
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
This is the one that comes back as a second fit-out rather than a snag.
-
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 Bhubaneswar job
The same classroom or office detail repeated across many blocks. Consistency across the order is where the value is.
05 / Supply
Getting it to Bhubaneswar, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three to four days |
| Dispatch | 2 to 4 working days |
| To site | three to four 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 fifteen hundred kilometres, normally three to four days on a dedicated truck.
Questions from Bhubaneswar projects
What makes auditorium acoustics and soundproofing different in Bhubaneswar?
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. The same classroom or office detail repeated across many blocks. Consistency across the order is where the value is.
Where should the budget go first on a Bhubaneswar 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 Bhubaneswar?
No. We manufacture in India and supply into Bhubaneswar. 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 Bhubaneswar site?
made at: Our own plant, Palwal, Haryana, reaches site in: three to four 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.
