INS Vikrant, Kochi – Acoustic Treatment

INS Vikrant, Kochi – Acoustic Treatment with Felt Panels & Baffles

Project Snapshot

Client & Location:

INS Vikrant (Indian Navy), Kochi, Kerala

Application:

Acoustic revamp of common hall space

Area Supplied:

650 m² of Echsorbix® Felt Acoustic Panels
300 m² of Acoustic Baffles

Objective:

Improve acoustic performance and reduce echo in a large common hall

Client Challenge

As part of the revamp of INS Vikrant, India’s first indigenous aircraft carrier, the common hall required acoustic enhancement to support gatherings, briefings, and daily activities. Key requirements included:

High-ceiling common hall required reduction of sound reflections for clear audibility during gatherings and briefings.

Materials needed to withstand naval conditions, heavy usage, and daily wear in an aircraft carrier environment.

Acoustic solution had to complement the iconic status of INS Vikrant with a visually appealing, high-quality finish.

Our Approach

Echsorbix® Felt Acoustic Panels:

650 m² of wall coverage to reduce reflections and enhance speech clarity.

Panels supplied in functional and aesthetically neutral tones, fitting seamlessly into the naval environment.

Acoustic Baffles:

300 m² of ceiling-mounted acoustic baffles to further absorb sound in the large hall.

Provided vertical sound absorption, targeting reverberation in open ceiling areas.

Products & Specifications

Echsorbix® Felt Acoustic Panels:

High-density acoustic felt for sound absorption.

Frequently Asked Questions

What was supplied to INS Vikrant at Kochi?

650 m2 of Echsorbix PET felt acoustic panels and 300 m2 of acoustic baffles, for the acoustic revamp of a common hall aboard India's first indigenous aircraft carrier.

What was the acoustic problem in the common hall?

A high-ceilinged space with reflective surfaces, where reflections reduced audibility during gatherings and briefings. In a hall used for briefings, intelligibility rather than loudness is the requirement, and it is set by reverberation time.

Why were both panels and baffles used?

Because they treat different surfaces. Wall panels address the perimeter reflections, and ceiling baffles address the largest reflective surface in a high-ceilinged hall. In a tall space, the ceiling treatment does most of the work on reverberation time.

Why is PET felt suitable for a naval environment?

It is durable, colourfast and resistant to the wear of heavy daily use, it cuts cleanly for shaped installations, and it carries Class A fire classification to ASTM E84 with UL GREENGUARD certification for low VOC emission, which matters in an enclosed shipboard space.

Does MMT Acoustix supply defence projects?

Yes. MMTPL supplies defence, government and public sector projects with the documentation such work requires, including ASTM and EN or ISO test reports, fire classification certificates and manufacturer authorisation.

Who manufactured the acoustic panels for INS Vikrant?

MMTPL (Mahabir Multi Tech Private Limited) manufactures the full range at its Palwal plant in Haryana, India, and supplies architects, consultants and turnkey contractors in India and 25+ export markets.
