UAS – Managing the impacts of underwater noise


Fee: No charge*

Time commitment—approximately two hours of self-study: 

  • Modules 1-4 (includes online video lectures, demonstration videos, quizzes)   

This modular, self-paced, online course shows you how to carry out biological risk assessments of environmental noise impacts. This knowledge is used for environmental impact assessments (EIAs) for wind farms, seismic surveys, shipping, dredging and other marine-related human activities. We take you through each step of executing a risk-based approach, from sound source description to impact management. This course enables you to understand how noise impact assessments work, whether you provide advice to regulators or if you perform assessments yourself.

About Underwater Acoustics Simulator (UAS)

The Underwater Acoustics Simulator (UAS) module in MIKE simulates propagation of noise in the far field with a state-of-the-art range-dependent acoustic model (RAM). UAS provides the option to specify several outputs in terms of sound exposure levels or transmission loss depending on environmental risk assessment objectives.


Are you a biologist, hydraulic engineer, acoustician, operations manager, regulator or scientist performing a marine environment-related EIA? Are you interested in understanding and modelling the impact of underwater sound on marine life? If yes, this free, self-paced course is for you.


Upon course completion, you will know how to use the Underwater Acoustics Simulator (UAS) module in MIKE Powered by DHI, which simulates noise propagation, to assess reactions of marine mammals and fish.


Each module includes videos and quizzes. It will take you around two hours to complete the course at a time that fits your needs and requirementsand in the comfort of your own office, home or any location convenient for you.
