NirDhwani Technology Pvt Ltd.

This is Part 2 of our previous post on the field experiment at Khadakwasla Lake, conducted in October 2017. Core research highlights of our field experiment included:

🔹Acoustic Propagation, which is crucial for accurate sonar operations
🔹Sound Speed Profile, which is important for enhancing the precision of acoustic measurements
🔹Sediment Classification for detailed analysis and classification of the lakebed sediments

The initiative focused on developing sonar-based sediment classification methodologies, building datasets for future research, and supporting sustainable water management strategies.

At NirDhwani Technology Pvt Ltd., we are committed to leveraging science, sonar technology, and data-driven insights to build practical solutions for sustainable and strategic decision making.

In today’s rapidly evolving maritime landscape, Noise & Vibration (N&V) management is no longer a niche engineering function; it has become central to operational efficiency and sustainability, and safety at sea. At NirDhwani Technology Pvt Ltd., we recognise the growing importance of N&V studies across marine platforms, spanning multiple critical applications:

🔹Crew Comfort & Habitability
🔹Underwater Noise Management
🔹Condition-Based Preventive Maintenance (CBPM)

Modern N&V analysis goes beyond traditional mechanical assessments. With advancements in computational modelling, sensor technologies, and Transfer Path Analysis (TPA), we can now better understand how noise propagates through airborne, structure-borne, duct-borne, and fluid-borne paths. At the same time, evolving global frameworks by organisations such as the International Maritime Organization - IMO and the International Organisation for Standardisation (ISO) continue to shape how the industry approaches noise mitigation and compliance. However, the challenge remains the lack of open-access ship data and the need for automated, AI-driven diagnostic systems.

💡 The way forward lies in integrating data analytics, automation, and domain expertise to build quieter, safer, and more sustainable marine ecosystems.

At NDT, we are committed to driving innovation in N&V management and bridging research with real-world underwater applications.
