Auditorium acoustics and soundproofing in Surat
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 is, and what it changes in a Surat room
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 Surat is mostly textile and processing units, diamond workshops, offices, showrooms, schools, clinics.
- Looms and processing machinery Continuous high level noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the walls of the hall.
- Cutting and polishing rooms Smaller, high frequency, and right next to people concentrating. Targeted treatment works here where it does not on a loom floor.
- Units beside housing Noise leaving the building matters as much as noise inside it, and they need different treatments.
- 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 Surat.
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 Surat, heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building.
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 Surat, 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 a cavity. Backing plus an air gap behind moves absorption lower, which matters in music rooms.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Surat, large school and college campuses in concrete and tile, with assembly halls and auditoria in constant use.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Surat usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / In this market
What the buildings in Surat do to the specification
- Looms and processing machinery
Continuous high level noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the walls of the hall.
- Cutting and polishing rooms
Smaller, high frequency, and right next to people concentrating. Targeted treatment works here where it does not on a loom floor.
- Units beside housing
Noise leaving the building matters as much as noise inside it, and they need different treatments.
- Humid and coastal
PET felt does not absorb moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- 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 assembly halls and auditoria in constant use.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Continuous high level noise for whole shifts. Enclosure or barrier at the machine is the honest fix, 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
- PET felt acoustic panels, 4 to 24 mm
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Smaller, high frequency, and right next to people concentrating. Targeted treatment works here where it does not on a loom floor.
- Wood wool acoustic panels, 20 mm
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Rear wall
The single worst surface in most halls, and the first one to treat. Noise leaving the building matters as much as noise inside it, and they need different treatments.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
Why the climate in Surat changes the material, not the target
Surat is hot and dry for most of the year, with dust and high daytime surface temperatures, and that narrows the material list before acoustics is discussed.
Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves.
The failure we design against here is dust ingress and thermal movement in long runs.
Where a consultant is already engaged on a Surat project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Surat job
Continuous high level noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the walls of the hall.
05 / Route to site
What the route into Surat actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two to three days |
| Dispatch | 2 to 4 working days |
| To site | two to three 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 eleven hundred kilometres, normally two to three days on a dedicated truck.
Questions from Surat projects
What makes auditorium acoustics and soundproofing different in Surat?
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. Continuous high level noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the walls of the hall.
Where should the budget go first on a Surat 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 Surat?
No. We manufacture in India and supply into Surat. 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 Surat site?
made at: Our own plant, Palwal, Haryana, reaches site in: two to three 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.
