Offering complete and comprehensive coverage of modern sonar spectrum system analysis, Underwater Acoustics: Analysis, Design and Performance of Sonar provides a state-of-the-art introduction to the subject and has been carefully structured to offer a much-needed update to the classic text by Urick. We recommend that users have a basic background in underwater acoustics, which enables them to assess the results from UAS. Sound levels can be characterised in a number of ways, the most common being sound pressure level (SPL). 1. Digital Underwater Acoustic Communications focuses on describing the differences between underwater acoustic communication channels and radio channels, discusses loss of transmitted sound in underwater acoustic channels, describes digital underwater acoustic communication signal processing, and provides a comprehensive reference to digital underwater acoustic communication equipment. History of Underwater Acoustics. The concepts of acoustics are exposed and applied in: room acoustics sound insulation, Underwater Acoustic Modeling and Simulation, Fourth Edition continues to provide the most authoritative overview of currently available propagation, noise, reverberation, and sonar-performance models. The first part focuses on the acoustic environment, antenna structures, and electric acoustic interface. Structural vibrations are now often included in acoustics. Observations and Physical Models. Unlike other books on this subject, which are often too specialized, this book is accessible to a wider audience. Standardization in Underwater Acoustics – Current status and on-going actions Christian Audoly1 1DCNS Research, Technopole de la Mer, 83190 Ollioules, France ABSTRACT Contrarily to airborne acoustics where many documents have been made available for different purposes for a long time, no standard was available for underwater acoustics until now.
