The constantly increasing shipping also increases the amount of underwater noise in the Baltic Sea. Propellers cause a continuous discrete-frequency noise, which can cause e.g. physiological stress to aquatic organisms and interfere with their navigation and interspecies communication.

The aim of the measure is to contribute to implementation and further development of the regulations drawn up by the International Maritime Organization IMO to decrease underwater noise caused by mercantile shipping. The aim is to adopt the goals and regulations set by IMO to reduce noise emitted by marine engines, propellers, and hulls in national legislation.
