Shipping Radiated Noise Estimation Using AI.
This research note highlights commercial ships are the major source of underwater radiated noise, which is generated because of interaction between hull, water and propeller cavitation that lies in the low-frequency range. It states that various…
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…
Mapping Snapping Shrimp Noise In The Indian Ocean Region: Impact On Sonar.
The Project discusses the impact of snapping shrimp on sonar systems in the Indian Ocean Region (IOR). Snapping shrimp are a major source of high-frequency noise in the ocean and their activities and habitation in shallow waters…
Low Frequency Shipping Ambient Noise Mapping For Passive Sonar Simulator.
The research note talks about an ingenious Passive Sonar Simulator (PSS) that the authors aim to develop using real time data inputs will be a critical tool for fulfilling our audacious objectives. The research note suggests that the complex tropical littoral waters of the Indian Ocean Region provide us with challenges to…
3D Shipping Radiated Noise Mapping.
The project undertaken is a step forward in the direction to explore and build a better acoustic capacity in the Indian Ocean Region (IOR) required for the enhanced Underwater Domain Awareness (UDA). It says that a 3D sound map…
Mapping Snapping Shrimp Noise In The Indian Ocean Region.
The article discusses the use of snapping shrimp noise in the Indian Ocean Region (IOR) to improve underwater acoustic systems. Snapping shrimp produce loud snaps that can disrupt underwater communication. The characteristics of snapping shrimp, analyzes the…
Analysis of Underwater Radiated Noise Based On Vessel Hull Vibrations.
This article discusses the issue of ocean pollution, specifically the impact of increased ambient noise on marine life, caused by anthropogenic (human-induced) sources such as maritime shipping and seismic exploration by the oil/gas industry…
