The book starts with the physics of sound and its interactions with surfaces, building a theoretical base. It then examines sonar technology, covering its development and uses in marine biology and navigation. Finally, it looks at echo-based techniques in fields like medical ultrasound and non-destructive testing.
Throughout the chapters, experimental data from acoustics, oceanographic surveys, and medical case studies support the arguments. It's designed for physics and engineering students, as well as professionals in acoustics, offering accessible explanations of complex equations with illustrative examples.
