Auditorium acoustics and soundproofing in Vellore
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. Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
- 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 material, and what it actually does on a Vellore job
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.
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Work reaching us from Vellore is mostly teaching hospitals, engineering campuses, lecture theatres, hostels, offices, hotels.
- Clinical privacy Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- Lecture theatres Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- Hostels and residences Students living next to each other and to corridors, where separating detail does 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 Vellore.
02 / The build-up
What goes where, from the structure in
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Vellore, 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.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Vellore, kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Vellore, very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
Architects working in Vellore 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 Vellore
- Clinical privacy
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- Lecture theatres
Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- Hostels and residences
Students living next to each other and to corridors, where separating detail does the work.
- Five days by road
A long run, confirmed before dispatch, with samples sent ahead of the order.
- Assembly and performance rooms
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
- School and campus buildings
Very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- Wood wool acoustic panels, 1200 x 600 mm
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Students living next to each other and to corridors, where separating detail does the work.
- Wood wool acoustic panels, 400 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
Why the climate in Vellore changes the material, not the target
Vellore 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 / Straight talk
The six errors that cost the most
-
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 Vellore job
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
05 / Logistics
Supply into Vellore, 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 two hundred kilometres, normally five days on a dedicated truck.
Questions from Vellore projects
What makes auditorium acoustics and soundproofing different in Vellore?
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music. Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
Where should the budget go first on a Vellore 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 Vellore?
No. We manufacture in India and supply into Vellore. 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 Vellore 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.
