Underwater Radiated Noise (URN) poses a growing threat to marine biodiversity due to increasing human maritime activities. This study explores how combining technology-driven solutions—such as advanced sensors, acoustic modeling, and noise mitigation systems—with strong policy frameworks can achieve effective URN management. By strengthening monitoring capacity, promoting stakeholder awareness, and aligning with global standards, the research proposes a comprehensive framework for sustainable noise management in the Indian Ocean and beyond.
"
1. Technological Innovations: Focus on noise reduction technologies, real-time acoustic monitoring, and Source–Path–Receiver (SPR) modeling for effective URN control.
2. Acoustic Capacity Building: Promotes the “See, Understand, and Share” framework to enhance underwater acoustic awareness and data sharing.
3. Policy Interventions: Reviews IMO MEPC.1/Circ.906 guidelines and international initiatives like the EU’s noise pollution limits for marine protection.
4. Marine Spatial Planning & Stakeholder Engagement: Integrates data-driven marine management with stakeholder collaboration to ensure sustainable ocean governance.
