Radiated underwater noise levels of two research vessels, evaluated at different acoustic ranges in deep and shallow water
Bibliographic record
Abstract
Within the scope of a NATO research project on onboard signature management, an extensive international measurement campaign was carried out in 2011. Two naval research vessels, CFAV Quest from Canada and FS Planet from Germany, were participating in the program. Both ships were ranged at Loch Fyne (UK), at open seas, in Heggernes (Norway), in Aschau (Germany), and Brest (France). One of the objectives of the research program is the evaluation of differences in reported underwater acoustical radiated noise levels of the ships under various boundary conditions. Quest and Planet sailed with a number of fixed machinery configurations like slow speed, high speed, and shaker excitation at certain structural points at each measurement site, respectively. The environmental conditions comprised deep water and shallow water as well as free field conditions at open seas. Both vessels are equipped with a large number of accelerometers, located at the main noise sources and along the hull frames of the ships. Additionally, at each acoustic range, runs with a towed sound source as a reference source were performed. In the presentation, a comparison of the first results of the radiated noise levels will be given.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
