Nir Dhwani
Technologies

The ocean, representing over two-thirds of the world’s surface area, is one of the least explored domains. At Nir Dhwani, we strive to change this status quo in collaboration with all stakeholders related to the Underwater Domain.

Our approach to turnkey projects is holistic. Our focus on multi-disciplinary interventions enable customer organizations to transcend operational silos.

Our unparalleled strength in acoustic signal processing deliver technologies, products and insights to unlock the potential of our Blue planet in a sustainable manner.

“Acoustic capability building lies at the core of Nir Dhwani’s foundation: it enables us to deliver transparency and monitor every development pertaining to the Underwater Domain for correlation and prediction of associated events”

Dr. (Cdr) Arnab Das. Founder & Director

Its In Our Name

Dedicated to building acoustic capability and capacity in the underwater domain, Nir Dhwani Technologies derives its name from the combination of two Sanskrit words “Nir” and “Dhwani.” The word “Nir” denotes water- the substance that makes up over seventy per cent of our blue planet earth; “Dhwani” or sound connotes our focus on acoustic capability.

Our Niche

As a start-up with capabilities in Acoustic Signal Processing Hardware & Software driven products and solutions, NDT has delivered multiple innovations to comprehensively support every dimension of the Underwater Domain. It undertakes turnkey solutions with extensive research based design & development projects alongside field experimental work.
