Auditorium acoustics and soundproofing in Ludhiana
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 Ludhiana 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 Ludhiana is mostly knitting and textile units, workshops, worker areas, offices, showrooms, schools, clinics.
- Machine noise, all shift Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Industry beside housing Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- Hard halls, no intelligibility Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- 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 Ludhiana.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Ludhiana, agro processing and light engineering plant, with generator sets and machinery close to occupied buildings.
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 Ludhiana, 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
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Ludhiana, large school and college campuses in concrete and tile, with halls carrying assembly and performance.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
If you are specifying for a Ludhiana project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What the buildings in Ludhiana do to the specification
- Machine noise, all shift
Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Industry beside housing
Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- Hard halls, no intelligibility
Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- One to two days by road
A dedicated truck from Palwal, with samples sent ahead so you can check the material before committing.
- 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
Large school and college campuses in concrete and tile, with halls carrying assembly and performance.
04 / Room by room
What each space in a Ludhiana project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- 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. Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- 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. Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- 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
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate
Durability in Ludhiana, before acoustics is discussed
Ludhiana 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.
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
Where this kind of project usually fails
-
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
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Ludhiana job
Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
05 / Getting it there
Supply into Ludhiana, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | one to two days |
| Dispatch | 2 to 4 working days |
| To site | one to two 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 three hundred and fifty kilometres. Full loads on a dedicated truck, smaller consignments on a shared vehicle.
Questions from Ludhiana projects
What makes auditorium acoustics and soundproofing different in Ludhiana?
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. Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
Where should the budget go first on a Ludhiana 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 Ludhiana?
No. We manufacture in India and supply into Ludhiana. 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 Ludhiana site?
made at: Our own plant, Palwal, Haryana, reaches site in: one to two 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
Tell us the room, we will tell you the build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
