Auditorium acoustics and soundproofing in Ahmedabad
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 material, and what it actually does on a Ahmedabad 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.
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 Ahmedabad is mostly textile and processing units, institutional buildings, offices, auditoriums, schools, hospitals.
- Textile machinery runs all shift Continuous machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
- Ambitious new buildings Exposed concrete and brick used as the finish, which looks superb and reflects almost everything. Absorption has to go where it will not fight the architecture.
- Dry heat PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- 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 Ahmedabad.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Ahmedabad, heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building.
Feature wall only. Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Ahmedabad, 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.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Ahmedabad, large school and college campuses in concrete and tile, with assembly halls and auditoria in constant use.
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 Ahmedabad project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.

What decides the build-up in Ahmedabad
- Textile machinery runs all shift
Continuous machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
- Ambitious new buildings
Exposed concrete and brick used as the finish, which looks superb and reflects almost everything. Absorption has to go where it will not fight the architecture.
- Dry heat
PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- Two days from the plant
A short run by Indian standards, so freight is cheap and samples arrive quickly.
- 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 machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- 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. Exposed concrete and brick used as the finish, which looks superb and reflects almost everything. Absorption has to go where it will not fight the architecture.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- 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. PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- PET felt acoustic panels, 4 to 24 mm
- 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
For a Ahmedabad interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Conditions
What the Ahmedabad climate rules in and rules out
Ahmedabad 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.
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 / Straight talk
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
Small on the drawing, expensive on site, and almost always found after handover.
-
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 Ahmedabad job
Continuous machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
05 / Getting it there
Supply into Ahmedabad, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two days |
| Dispatch | 2 to 4 working days |
| To site | 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 nine hundred kilometres, normally two days on a dedicated truck.
Questions from Ahmedabad projects
What makes auditorium acoustics and soundproofing different in Ahmedabad?
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 machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
Where should the budget go first on a Ahmedabad 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 Ahmedabad?
No. We manufacture in India and supply into Ahmedabad. 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 Ahmedabad site?
made at: Our own plant, Palwal, Haryana, reaches site in: 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
Send a plan and a section, get a real build-up
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.
