Acoustics

Analysis or measurement of the noise made by a device.

An operating marine renewable energy device may produce low levels of noise from the rotation of turbine blades and generators, movement of floating devices on the surface, or strumming of mooring lines and cables. While measurements of a device’s acoustic emissions are typically required as part of a project’s environmental impact assessment, acoustic emission monitoring can also be used to remotely monitor the health of a device and to detect device failure modes as part of a condition monitoring plan.
