Vector acoustic observations of ship noise and influence of sediment compressional speed gradients and shear rigidity in modeling

2023
Open Access Peer Reviewed Research Article

Journal of the Acoustical Society of America

Dahl, P.H., Dall'Osto, D.R.,

Observability of the effects of seabed shear rigidity varies with source type, fr. Range, and measurement geometry. Measurements of underwater noise from a passing ship made...

Dahl, P.H., Dall'Osto, D.R.

Broadband noise emissions exhibit frequency bands where acoustic energy is greater than kinetic., the inverse is true for neighbouring frequency bands. This is characteristic of interference...
