Underwater Radiated Noise Management.
The Underwater Radiated Noise (URN) Management on-board marine platforms is an interesting research area with varied stakeholder interests. The first is the ship…
Shipping Radiated Noise Estimation Techniques.
This research note aims to identify all the ‘Shipping Radiated Noise Estimation Techniques’ that have been developed so far, which enables us to derive shipping radiated noise based on Automatic Identification…
Review To 3D Mapping Of Low Frequency Ambient Shipping Noise.
The Indian Ocean Region has deep roots in overseas trade routes and several vessels finding their way through it, making it one of the most important sea areas today. As a result, it has also given rise to the Low frequency shipping noise radiated from the…
Radiated Noise Generation
This paper states that the standard modes of signal transmission underwater are acoustic waves and a large majority of marine life uses sound waves for regular movement. Therefore, the classification and analysis of sources of underwater noise becomes imperative. The study classifies the noise in context of ships into following…
Mathematical Study On Underwater Channel Modelling In Indian Ocean Region.
Underwater acoustics is the study of the propagation of sound in water and the interaction of the…
Design And Development Of Autonomous Underwater Vehicles (AUVs) For Underwater Ambient Noise Validation.
India and many third world countries depend on rainfall for their domestic and other freshwater requirements. The non-monsoon months that constitute around 65% of the period annually, is supported by the water stored in the reservoirs. However, due to the process of water flow and…
Calculation of Sound Transmission Loss in Ocean Using Different Wave Equation Models
Underwater acoustics is the study of the propagation of sound in water and the interaction of the acoustic (sound) waves with the water, its contents, and its boundaries. While sound moves at a much faster speed…
Acoustic Method of Dark Ship Detection In the Indian Ocean Region Using Low Frequency Spatio-temporal Noise Map (software)
This research note highlights the challenges of detecting and tracking “dark ships” involved in illegal activities within a nation’s Exclusive Economic Zone (EEZ), particularly in the Indian Ocean region. These ships often turn off their Automatic Identification System…
