Auditorium acoustics and soundproofing in Thane
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 you are buying, and what it fixes in Thane
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 Thane is mostly residential towers and redevelopment, offices, malls and retail, restaurants, schools, clinics.
- Impact noise from above Footfall through a slab is the most common complaint we get from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Redevelopment at speed Old buildings replaced by towers, built fast to a fixed cost. Acoustic detail is easy to lose unless it is specified early.
- Lifts, pumps and services Shafts and pump rooms sit next to bedrooms in tight plans. That is an isolation job at the source.
- 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 Thane.
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 Thane, 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.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Thane, 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 Thane, schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
Architects working in Thane usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

What decides the build-up in Thane
- Impact noise from above
Footfall through a slab is the most common complaint we get from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Redevelopment at speed
Old buildings replaced by towers, built fast to a fixed cost. Acoustic detail is easy to lose unless it is specified early.
- Lifts, pumps and services
Shafts and pump rooms sit next to bedrooms in tight plans. That is an isolation job at the source.
- Coastal humidity
PET felt does not absorb moisture or feed mould, which matters where monsoon damp defeats mineral products.
- 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
Schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Footfall through a slab is the most common complaint we get from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Wooden slat acoustic panels, MDF, FR MDF, HDF or HDHMR
- 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
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Old buildings replaced by towers, built fast to a fixed cost. Acoustic detail is easy to lose unless it is specified early.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- 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
-
Rear wall
The single worst surface in most halls, and the first one to treat. Shafts and pump rooms sit next to bedrooms in tight plans. That is an isolation job at the source.
- 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
- Ceiling baffles and clouds, ASTM C423
For a Thane interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate
Durability in Thane, before acoustics is discussed
Thane is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
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.

The six errors that cost the most
-
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
It sounds like a small detail until the room is finished and the complaint arrives.

Treating it as a generic Thane job
Footfall through a slab is the most common complaint we get from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
05 / Supply
Getting it to Thane, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three to four days |
| Dispatch | 2 to 4 working days |
| To site | three to four 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 fourteen hundred kilometres, normally three to four days on a dedicated truck.
Questions from Thane projects
What makes auditorium acoustics and soundproofing different in Thane?
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. Footfall through a slab is the most common complaint we get from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
Where should the budget go first on a Thane 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 Thane?
No. We manufacture in India and supply into Thane. 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 Thane site?
made at: Our own plant, Palwal, Haryana, reaches site in: three to four 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.
