Abstract

It is an efficient method to model ship radiated noise as quasi-periodic random sound pulse sequences. Based on the model, the characteristics changes of ship noises after through shallow-water waveguides are discussed. Theoretical analysis and numerical simulation show that random waveguides and multi-path effects can bring additional much transmission loss for the noise line spectra, demonstrating the instability of ship radiated noise line spectra to a certain extent, and providing some theoretical support for advanced studies of ship radiated noise.
