Applied Underwater Acoustics provides a foundational reference for research and practical analysis across marine environments. The volume equips readers to solve technical problems in underwater sound, requiring no prior background in the field.
The text examines fundamental principles including sound propagation, seawater absorption, acoustic scattering, ambient noise, and shallow-water dynamics. Additional coverage addresses seafloor interactions, inverse methods, signal processing, and finite-amplitude wave behavior.
Intended for graduate and postgraduate students, physicists, scientists, and engineers in acoustics, each self-supporting chapter introduces physical principles alongside application roadmaps and comprehensive literature references, highlighting equation limits rather than mathematical derivations.
