In order to study the applicability of different regularization parameter methods in ship-radiated noise evaluation under various noise levels, and reduce the evaluated errors, the paper systematically introduces a method of ship-radiated noise evaluation based on the operational transfer path analysis (OTPA), and discusses the applicability of the singular value decomposition (SVD) method, Tikhonov regularization based on L-curve and generalized cross-validation (GCV) in solving the inverse problem of the transfer function.Then, the Tikhonov method based on quasi-optimality (Q-O) criterion was proposed to reduce the errors.Experiments with a reduced-scale cabin in Thousand Islet Lake show that the performance of the SVD method is the worst under various noise levels, and the performance of L-curve, GCV and Q-O criterion methods are almost the same.However, with the noise levels increasing, the L-curve method is better than GCV; and the Q-O criterion method is better than L-curve, which can reduce errors by up to 0.42 dB compared with the L-curve method and 1.19 dB compared with the SVD method.Meanwhile, the robustness analysis of Q-O criterion shows that the parameter can be regarded as the quasi-optimal regularization parameter, which can provide guidance for engineering application of ship-radiated noise evaluation.
