Books in the Modern Acoustics and Signal Processing series

Computational Ocean Acoustics presents state-of-the-art numerical techniques to solve the wave equation in heterogeneous fluid-solid media. Thoroughly revised, this volume completely updates the material in the first edition and includes new models based on current research.

This book offers a computational framework for modeling active exploratory listening that assigns meaning to auditory scenes. Understanding auditory perception and cognitive processes involved with our interaction with the world are of high relevance for a vast variety of ICT systems and applications. Human beings do not react according to what they perceive, but rather, they react on the grounds of what the percepts mean to them in their current action-specific, emotional and cognitive situation. Thus, while many models that mimic the signal processing involved in human visual and auditory processing have been proposed, these models cannot predict the experience and reactions of human users. This book presents a model that incorporates both signal-driven (bottom-up), and hypothesis-driven (top-down) processing.

This reference fully explores the particulars of the sounds made by all standard instruments in a modern orchestra as well as the human voice. It discusses how acoustics vary in different rooms and offers recommendations for adjustment.

This improved and updated second edition covers the theory, development, and design of electro-acoustic transducers for underwater applications. The book includes new advances in transducer design and transducer materials and has been completely reorganized to be suitable for use as a textbook, as well as a reference or handbook.

Market: Those interested in speech, especially speech production, and graduate students studying the anatomy and physiology of speech.

Topics covered include acoustical measurement principles, in-depth critical study of uncertainty applied to acoustical measurements, digital signal processing from the basics, and metrologically-oriented spectral and statistical analysis of signals.

New topics covered include: - inter-thermocline lenses and their effect on sound fields- weakly divergent bundles of rays - ocean acoustic tomography - coupled modes - sound scattering by anisotropic volume inhomogeneities with fractal spectra - Voronovich's approach to sound scattering from the rough sea surface.
