Statistics of distant shipping noise
The Journal of the Acoustical Society of America, 1973Distant shipping noise is modeled analytically as phase-random line components arriving from a number of independent sources. Three cases are distinguished as (a) all noise arrivals having the same intensity, (b) all having different intensity, and (c) mixtures of (a) and (b).

Classification of ships using underwater radiated noise
COMSIG 88@m_Southern African Conference on Communications and Signal Processing. Proceedings, 1989Concentrating mainly on the signal processing and physical models behind the algorithms used to classify ships by their underwater-radiated noise, the physical model for cavitation is expanded to include the losses by acoustical radiation and the heat transfer from the vapor to the fluid. The resulting equation allows one to find the characteristics of

Noise and Vibration Aboard Ship
1984The quality of shipboard habitability is the integrated effect of all factors determining the behaviour, health and well-being of the seafarer under his specific conditions of service, comprising: 1. Physical environment: exposure to noise and vibration, climatic conditions, illumination, work and leisure considerations; 2.

The Journal of the Acoustical Society of America
An automated ship Underwater Radiated Noise (URN) system has been developed and applied to process measurements of tens of thousands of commercial vessel transits, to produce the Enhancing Cetacean Habitat and Observation (ECHO) Program’s Ship URN database—believed now to be the largest existing ship URN database.

Noise-Reducing Ship Propeller Design
Applied and Computational EngineeringPropellers, as the core of ship propulsion systems, significantly impact vessel speed, fuel efficiency, and overall performance. Achieving a balance between hydrodynamic efficiency, cavitation reduction, and noise minimization remains a significant challenge in traditional propeller design.
