Underwater Acoustic channel is full of various impulsive sources due to which the underwater noise does not follow the standard Gaussian Probability Distribution Function (pdf). This makes the Underwater scenario a little more complicated and leads to performance issues in various fields of underwater applications, e.g. communication, signal processing,

Journal of Geophysical Research: Oceans, 1989
Numerous data on the spectra of underwater noise due to natural as well as artificial rain show a prominent and characteristic peak at a frequency around 14 kHz. It is argued that this acoustic emission is due to bubbles entrained in the liquid by the impact of raindrops.

We investigate the effect of the interior mechanical structure of the streamers on the flow noise. Simple algebraic forms are derived for the comparative performance of liquid and viscoelastic-filled streamers. The introduction of porous foam into liquid streamers is found to be a particularly effective way of attenuating low wave-number disturbances ...

Noise Reduction, with a Noise Reference, of Underwater Magnetic Signals
Digital Signal Processing, 1996Abstract Quinquis, A., and Rossignol, S., Noise Reduction, with a Noise Reference, of Underwater Magnetic Signals,Digital Signal Processing6(1996), 240–248. Faint signals embedded in noise are very difficult to detect. Depending on the available knowledge, various methods have been developed for the particular detection problem.

Underwater Noise Due to Marine Life
The Journal of the Acoustical Society of America, 1946The widespread use of underwater acoustical devices during the recent war made it necessary to obtain precise information concerning ambient noise conditions in the sea. Investigations of this subject soon led to the discovery that fish and other marine life, hitherto generally classified with the voiceless giraffe in noisemaking ability, have long ...

The impact of underwater noise
2022The description of sound as a form of energetic pollutant is very complex as is also its impact on aquatic life. Human activities causing continuous and implosive underwater noise, such as marine traffic, maintenance of ships, coastal tourism, marine research, military, offshore energy platforms, generation of ocean energies and construction operations
