Measurement of radiated ship noise

Proceedings of Meetings on Acoustics, 2013
A methodology is presented for measuring the radiated noise from a ship in shallow water, and deriving the source level spectrum. The method is applied to the measurement of dredgers in UK waters, vessels which are restricted to shallow water during aggregate extraction.

Control of Ship Radiated Underwater Noise

OCEANS 2019 MTS/IEEE SEATTLE, 2019
As human activity in the oceans has grown and scientific understanding of underwater noise has increased, it has been generally accepted that the growth of anthropogenic noise in the ocean has acute, chronic, and cumulative impacts on marine species, most notably marine mammals who depend on sound for foraging, breeding, predator avoidance, navigation,

Simulation of Dynamic Ship Radiated Noise Signal

2020 15th IEEE International Conference on Signal Processing (ICSP), 2020
The total intensity and the spectral distribution of ship’s radiated noise signal changes dynamically as the ship navigates. Conventional static simulation methods are focused on exhibiting non-changing or fixed patterns of signal’s characteristics.

Research on identification technology of ship radiated noise and marine biological noise

2017 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2017
The vocal mechanism and structure of ship radiated noise and marine biological noise are analyzed, and the differences of short-term inter-frame spectral similarity between the two kinds of noise are compared. On the basis of this, Pearson correlation coefficient variance of the spectral trend of the adjacent two frames in the short term of the framing

Underwater radiated noise from modern commercial ships

The Journal of the Acoustical Society of America, 2012
Underwater radiated noise measurements for seven types of modern commercial ships during normal operating conditions are presented. Calibrated acoustic data (<1000 Hz) from an autonomous seafloor-mounted acoustic recorder were combined with ship passage information from the Automatic Identification System.
