A Survey: Denoising Algorithm for Acoustics Signal

Anjali Singh, R. S. Kawitkar, M. Selva Balan


Underwater acoustics signal is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water and its boundaries. The water may be in the dam, ocean, a lake or a tank. There are some frequencies affiliated with underwater acoustics are between 10 Hz and 1 MHz .There are some major steps for underwater signal de-noising. The first step deals with signal pre-processing which including amplifying, filtering, and take use of analogy / digital (AD) technique to save signals as digital file. The underwater acoustic signal is affected by ocean interference and ambient noise disturbance during its propagation in ocean. Acoustic signal are the most important Parameter to convey data in underwater domain as a practical method. But the dams and reservoirs are increasingly exposed to sounds from human activities, such as shipping, Self-noise other different noise.
