Auditorium acoustics and soundproofing in Kochi
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. Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.
- 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 product, described honestly, for a Kochi brief
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.
Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.
Work reaching us from Kochi is mostly hotels and resorts, hospitals, offices, shipyard and industrial, houses, schools.
- Humidity and salt decide everything PET felt does not absorb moisture, shed fibre or feed mould. On a backwater or coastal site that is the whole material selection argument.
- Hospitality on the water Resorts and hotels where guest room isolation and restaurant acoustics are the two recurring briefs.
- Port and industrial work Shipyard and workshop noise where enclosure and mass do the work, not absorption.
- 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 Kochi.
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 Kochi, 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 Kochi, auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Kochi, schools and colleges are naturally ventilated with open corridors, so absorption alone will not fix intelligibility.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
What we see driving Kochi briefs
- Humidity and salt decide everything
PET felt does not absorb moisture, shed fibre or feed mould. On a backwater or coastal site that is the whole material selection argument.
- Hospitality on the water
Resorts and hotels where guest room isolation and restaurant acoustics are the two recurring briefs.
- Port and industrial work
Shipyard and workshop noise where enclosure and mass do the work, not absorption.
- Five to six days by road
A long run, so we confirm the schedule before dispatch and send samples ahead.
- Assembly and performance rooms
Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.
- School and campus buildings
Schools and colleges are naturally ventilated with open corridors, so absorption alone will not fix intelligibility.
04 / Room by room
Where the money goes on a Kochi project
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. PET felt does not absorb moisture, shed fibre or feed mould. On a backwater or coastal site that is the whole material selection argument.
- 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. Resorts and hotels where guest room isolation and restaurant acoustics are the two recurring briefs.
- 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. Shipyard and workshop noise where enclosure and mass do the work, not absorption.
- 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
What the Kochi climate rules in and rules out
Kochi 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.
On a Kochi job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
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
Small on the drawing, expensive on site, and almost always found after handover.
-
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 Kochi job
PET felt does not absorb moisture, shed fibre or feed mould. On a backwater or coastal site that is the whole material selection argument.
05 / Supply
What the route into Kochi actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five to six days |
| Dispatch | 2 to 4 working days |
| To site | five to six 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 four hundred kilometres, normally five to six days on a dedicated truck.
Questions from Kochi projects
What makes auditorium acoustics and soundproofing different in Kochi?
Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music. PET felt does not absorb moisture, shed fibre or feed mould. On a backwater or coastal site that is the whole material selection argument.
Where should the budget go first on a Kochi 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 Kochi?
No. We manufacture in India and supply into Kochi. 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 Kochi site?
made at: Our own plant, Palwal, Haryana, reaches site in: five to six 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.
