Propeller induced low and high frequency noise

    Project: Business Finland project

    Project Details


    The main goal of the PropNoise project is to develop methods to predict propeller induced underwater noise. The natural resources available in the arctic seas and the opening of the Northern Sea Route are increasing shipping in these regions. The increasing environmental awareness drives the international organizations to develop restrictions for underwater noise emitted from shipping at the arctic and other vulnerable sea regions. Propellers are the most important noise source of ships. The project helps to understand the phenomena in the propeller flows causing underwater noise. That helps to design propellers with lower acoustic emissions. The project also investigates methods to measure underwater noise of ships in acoustically shallow waters.
