Auditorium acoustics and soundproofing in Lucknow
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. Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
- 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.

What this material is and where it earns its place in Lucknow
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.
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
Work reaching us from Lucknow is mostly government and institutional buildings, colleges, hospitals, auditoriums, hotels, offices.
- Rooms built for listening Assembly halls and lecture theatres in concrete and tile defeat the speaker long before anyone calls the room echoey.
- Heritage alongside new build Old buildings that cannot be altered, and new institutional blocks where the acoustics were costed out of the BOQ.
- Medical privacy Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.
- 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 Lucknow.
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 Lucknow, 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 a cavity. Backing plus an air gap behind moves absorption lower, which matters in music rooms.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Lucknow, banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Lucknow, large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
For a Lucknow practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / Local conditions
What we see driving Lucknow briefs
- Rooms built for listening
Assembly halls and lecture theatres in concrete and tile defeat the speaker long before anyone calls the room echoey.
- Heritage alongside new build
Old buildings that cannot be altered, and new institutional blocks where the acoustics were costed out of the BOQ.
- Medical privacy
Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.
- Next day from the plant
A short run, so samples arrive quickly and freight stays cheap on large orders.
- Assembly and performance rooms
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
- School and campus buildings
Large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
04 / Room by room
What each space in a Lucknow project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Assembly halls and lecture theatres in concrete and tile defeat the speaker long before anyone calls the room echoey.
- 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. Old buildings that cannot be altered, and new institutional blocks where the acoustics were costed out of the BOQ.
- 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. Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.
- Wood wool acoustic panels, 400 kg per cubic metre
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft

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 / Durability
Why the climate in Lucknow changes the material, not the target
Lucknow 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.
On a Lucknow job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
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
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
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating it as a generic Lucknow job
Assembly halls and lecture theatres in concrete and tile defeat the speaker long before anyone calls the room echoey.
05 / Getting it there
How material reaches a Lucknow site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a day |
| Dispatch | 2 to 4 working days |
| To site | a day |
| 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 five hundred kilometres, normally next day on a dedicated truck.
Questions from Lucknow projects
What makes auditorium acoustics and soundproofing different in Lucknow?
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night. Assembly halls and lecture theatres in concrete and tile defeat the speaker long before anyone calls the room echoey.
Where should the budget go first on a Lucknow 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 Lucknow?
No. We manufacture in India and supply into Lucknow. 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 Lucknow site?
made at: Our own plant, Palwal, Haryana, reaches site in: a day, 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.

Send the drawings, get a straight answer
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
