Underwater Radiated Noise from Ships: Defining the Problem with Mary Wisz, Senior Researcher, DTU

From the meeting:  "The Silent Threat Beneath the Waves: Underwater Radiated Noise from Ships"

As global shipping traffic grows, so does an invisible—but powerful—form of pollution: Underwater Radiated Noise (URN). This low-frequency hum, emitted by ships, is disrupting life beneath the surface.

Whales and dolphins struggle to communicate, navigate, and find mates.

Fish and marine species may abandon their habitats or alter their feeding and migration patterns.

But there’s hope. Designers, Consultants, and Regulators are working together to mitigate issues. From quieter propeller designs to new international guidelines.

 Join us for an eye-opening event where we dive into:

• Why URN matters – and what’s at stake for marine ecosystems
• How URN is measured – and practical strategies for reducing it
• Real-world results – insights from full-scale testing and innovation in action
