Auditorium acoustics and soundproofing in Bareilly
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.

01 / The material
What this material is and where it earns its place in Bareilly
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 Bareilly is mostly furniture and timber units, colleges, hospitals, offices, auditoriums, banquet halls.
- Saws and sanders High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
- New institutional buildings Concrete and tile put up quickly, with acoustics discovered at handover rather than designed out.
- Dust and workshop conditions PET felt does not shed fibre or hold dust the way soft mineral products do, which matters in a woodworking environment.
- 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 Bareilly.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Bareilly, 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.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bareilly, 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
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bareilly, large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What we see driving Bareilly briefs
- Saws and sanders
High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
- New institutional buildings
Concrete and tile put up quickly, with acoustics discovered at handover rather than designed out.
- Dust and workshop conditions
PET felt does not shed fibre or hold dust the way soft mineral products do, which matters in a woodworking environment.
- One to two days by road
A dedicated truck from Palwal, with samples ahead of the order.
- 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.

Where the money goes on a Bareilly project
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Concrete and tile put up quickly, with acoustics discovered at handover rather than designed out.
- Wood wool acoustic panels, 20 mm
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
Rear wall
The single worst surface in most halls, and the first one to treat. PET felt does not shed fibre or hold dust the way soft mineral products do, which matters in a woodworking environment.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- Ceiling baffles and clouds, ASTM C423
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
Why the climate in Bareilly changes the material, not the target
Bareilly 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.
Where a consultant is already engaged on a Bareilly project, we supply to their specification and send the test reports rather than describing them. More on 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
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Bareilly job
High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
05 / Supply
Getting it to Bareilly, with real dates
| 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, normally one to two days on a dedicated truck.
Questions from Bareilly projects
What makes auditorium acoustics and soundproofing different in Bareilly?
Banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night. High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
Where should the budget go first on a Bareilly 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 Bareilly?
No. We manufacture in India and supply into Bareilly. 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 Bareilly 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
Drawings in, BOQ and a delivered date out
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.
