The Journal of the Acoustical Society of America, 2011
Throughout 2010, underwater recordings have been made of each ship passing two separate Haro Strait nodes of the OrcaSound.net hydrophone network. About 20 ships pass each day. Each ship has been identified in real time [automatic identification system (AIS)].

The Journal of the Acoustical Society of America, 1975
A research program has been organized by the Swedish Ship Research Foundation. One of the objectives of the program has been to develop a noise prediction method. In its first form this prediction method is of empirical type, based on extensive noise level and vibration measurements in three reference ships.

Array element localization using ship noise
The Journal of the Acoustical Society of America, 2009This paper describes a method of estimating hydrophone positions in a receiver array using the noise from a passing ship. Relative arrival times of the ship-noise signal between pairs of hydrophones are obtained from several time windows of data (corresponding to different ship locations) by cross-correlating the band-pass filtered time series.

Advancing glider-based acoustic measurements of underwater-radiated ship noise.
Journal of the Acoustical Society of AmericaOcean gliders are versatile and efficient passive acoustic monitoring platforms in remote marine environments, but few studies have examined their potential to monitor ship underwater noise.

Parametric Analysis of Ship Noise Spectra
IEEE Journal of Oceanic Engineering, 2017A growing attention has been recently devoted to the impact of the underwater noise field generated by shipping activities on the marine fauna. A key aspect for the quantification of such impact is a proper model of the source levels radiated from the vessels.

Abstract : Geoacoustic inversion from tow-ship noised data acquired on a horizontal towed array is discussed. Through simulations and experimental results, it is shown that even very quiet ships radiate sufficient noise power to enable self-noise inversion of basic geoacoustic parameters such as effective bottom velocity.

Analysis of ship noise from underwater ambient noise
2016 Conference on Advances in Signal Processing (CASP), 2016Underwater signal processing includes several application areas like military application, disaster detection, finding natural resources, etc. When signal transmits through water, it may get overlap due to some inherent mechanisms like ship noise, wind noise, marine mammals noise, noise generated during all stages of oil production, and due to other ...

Propeller Induced Noise in Ships
SNAME Propellers '81 Symposium, 1981The propeller noise induced in the accommodation spaces on as ship is a function of the acoustical source strength of the propeller ana of the response of the hull plates above the propeller. For a cavitating propeller the source strength is primarily determined by the volume variation of the cavity on each propeller blade. The cavitation volume can be
