Results from off-board noise prediction study in ORCA-class training vessel / Graeme Larsen, Jasper Dupuis, Layton Gilroy. : D68-2/003-2021E-PDF
"Transport Canada is interested in the real-time estimation of underwater radiated noise based on on-board measurements due to its impact on marine mammals. At Transport Canada's request, Defence Research and Development Canada (DRDC) performed a trial to measure both on-board vibrations and off-board underwater noise produced by an ORCA-class patrol vessel. The post-trial work is a first attempt at adapting real-time acoustic signature estimation procedures that have previously been developed by an international partner (COSIMAR, STEAM and MEASURE trials). Analysis of the trial data shows that it is possible to accurately reconstruct the off-board noise spectrum using few hull and machine-mounted accelerometers. It should also be possible to estimate the cavitation state of the propeller based on the predicted noise levels"--Abstract, page i.
