A way ahead view on URN Management
Effective management of underwater radiated noise (URN) is crucial for both
environmental conservation and operational efficiency in maritime activities. Acoustic stealth
technologies are pivotal in minimizing detection risks for submarines and surface vessels,
thereby enhancing survivability and mission success. However, challenges such as
inconsistent global regulations, inadequate data on noise impacts, and technological
limitations in monitoring and mitigation persist.
