Auditorium acoustics and soundproofing in Bengaluru
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.

What this material is and where it earns its place in Bengaluru
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 Bengaluru is mostly tech campuses, apartment towers, microbreweries and restaurants, clinics, schools, studios.
- Floors full of simultaneous calls Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
- Campus scale repetition The same detail across many floors and buildings. Consistency across a large order matters more than the headline figure on one sheet.
- Microbreweries and hard rooms Exposed brick, steel and glass by design, then packed at capacity. The ceiling plane is usually the only surface left to work with.
- 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 Bengaluru.
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 Bengaluru, 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
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Bengaluru, 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
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bengaluru, large engineering and school campuses with lecture halls, seminar rooms and hostels repeating the same detail across many blocks.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
Architects working in Bengaluru 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 / Local conditions
What decides the build-up in Bengaluru
- Floors full of simultaneous calls
Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
- Campus scale repetition
The same detail across many floors and buildings. Consistency across a large order matters more than the headline figure on one sheet.
- Microbreweries and hard rooms
Exposed brick, steel and glass by design, then packed at capacity. The ceiling plane is usually the only surface left to work with.
- Mild climate, sealed buildings
Air conditioned floors stay closed, so sound accumulates rather than escaping. Absorption has to be balanced, not maximised.
- 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 engineering and school campuses with lecture halls, seminar rooms and hostels repeating the same detail across many blocks.
04 / Room by room
What each space in a Bengaluru project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
- Wooden slat acoustic panels, MDF, FR MDF, HDF or HDHMR
- 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. The same detail across many floors and buildings. Consistency across a large order matters more than the headline figure on one sheet.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- 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. Exposed brick, steel and glass by design, then packed at capacity. The ceiling plane is usually the only surface left to work with.
- 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
- Acoustic carpet and rugs, 64 sq ft per pack
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
Durability in Bengaluru, before acoustics is discussed
Bengaluru 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.
Where a consultant is already engaged on a Bengaluru project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Straight talk
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
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 Bengaluru job
Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
05 / Route to site
Getting it to Bengaluru, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four to five days |
| Dispatch | 2 to 4 working days |
| To site | four to five 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 twenty one hundred kilometres, normally four to five days on a dedicated truck.
Questions from Bengaluru projects
What makes auditorium acoustics and soundproofing different in Bengaluru?
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. Hundreds of people on video calls in one room is the defining Bengaluru brief. Absorption alone will not deliver privacy. Ceiling, screens and layout have to work together.
Where should the budget go first on a Bengaluru 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 Bengaluru?
No. We manufacture in India and supply into Bengaluru. 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 Bengaluru site?
made at: Our own plant, Palwal, Haryana, reaches site in: four to five 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
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.
