Winston Churchill famously claimed that the submarine war in the Atlantic was the only campaign of the Second World War that really frightened him. If the lifeline to north America had been cut, Britain would never have survived; there could have been no build-up of US and Commonwealth forces, no D-Day landings, and no victory in western Europe. Furthermore, the battle raged from the first day of the war until the final German surrender, making it the longest and arguably hardest-fought campaign of the whole war.The ships, technology and tactics employed by the Allies form the subject of this book. Beginning with the lessons apparently learned from the First World War, the author outlines inter-war developments in technology and training, and describes the later preparations for the second global conflict. When the war came the balance of advantage was to see-saw between U-boats and escorts, with new weapons and sensors introduced at a raid rate. For the defending navies, the prime requirement was numbers, and the most pressing problem was to improve capability without sacrificing simplicity and speed of construction. The author analyses the resulting designs of sloops, frigates, corvettes and destroyer escorts and attempts to determine their relative effectiveness.While the basic characteristics of these ships are well known, this was the first book to look at their cost-effectiveness in terms of anti-submarine warfare. Based on a lifetime's experience of designing warships, the author's fascinating insights, presented in this new softcover edition, will be of interest to enthusiasts and valuable to naval historians alike.

With two new chapters, improved artwork, and significant updates made throughout to increase readability, the fourth edition of Audiology: Science to Practice continues to be the most comprehensive textbook for audiology and hearing science courses, as well as for health care professionals wanting a better understanding of hearing science and audiology practices. It is written in a style that makes new or difficult concepts relatively easy to understand, while still providing more coverage of hearing and vestibular science and clinical audiology than other introductory texts.Topics include information about the profession of audiology, acoustics, anatomy and physiology of the auditory and vestibular systems, preparing for the patient, otoscopy, pure-tone audiometry and speech measures, audiogram interpretations, masking, tympanometry, acoustic reflexes, wideband acoustic immittance, otoacoustic emissions, auditory brainstem responses, hearing screening, hearing aids, assistive listening aides, cochlear and other implantable devices, vestibular evaluation, descriptions of auditory and vestibular disorders, and aural rehabilitation. There is also a chapter on the roles of speech-language pathologists related to understanding and caring for persons with hearing and balance concerns. Where relevant, the material includes evidence-based practice.New to the Fourth EditionTwo new chapters: Role of the Speech-Language Pathologist and Other Treatments and (Re)habilitation of Hearing and Balance DisordersMany new beautifully drawn two-color anatomy and physiology illustrationsBlack and white figures have been color-enhanced Several chapters were reorganized and updated to include vestibular anatomy, physiology, and vestibular disorders within the relevant auditory chaptersA separate chapter on vestibular evaluation and bedside screeningMany chapters expanded to provide information on environmental factors that affect the transmission of sound, signal-to-noise ratio, preparation for testing, cerumen management, assistive listening technology systems (HATS), and status of over-the-counter hearing aids Updated references and standards throughoutKey FeaturesMany illustrations than other texts to help clarify and expand on key concepts Chapters begin with a list of learning objectives and end with key referencesPunctuated with historical and informational side boxesAn easy-to-read writing style to help students understand scientific concepts Key terms highlighted throughout with a comprehensive end-of-book glossary A PluralPlus companion website with PowerPoint lecture slides and an image bank for instructors, James Jerger's chapter on the History of Audiology, and moreThe authors have also created a companion study aid for students, Audiology Workbook, Fourth Edition.

Audiology Workbook, Fourth Edition is a companion study aid to the textbook, Audiology: Science to Practice, Fourth Edition. It can also serve as an appropriate supplement to other introductory audiology textbooks or class lectures. The Audiology Workbook focuses on exercises and questions in hearing and vestibular science and audiology clinical principles and procedures that are beneficial for students in an undergraduate communication science and disorders program and those in a graduate-level AuD program. It is also a great study resource for the Audiology Praxis Exam.The fourth edition is composed of an abundance of questions and activities designed to reinforce students' knowledge of concepts and procedures that are, traditionally, difficult to master. There are questions and activities on 1) properties of sound, such as drawing waveforms; calculating frequencies/periods, amplitudes, and phases, 2) auditory and vestibular anatomy and physiology of the auditory and vestibular systems, including diagrams to label, 3) procedures for obtaining pure-tone thresholds and interpreting/describing audiograms 4) masking for pure-tone and speech tests, 5) performing and interpreting speech test, tympanograms, wideband acoustic immittance, acoustic reflexes, 6) understanding and interpreting evoked physiologic responses, including OAEs, ABRs, ECochG, ENOG, VEMP, 7) clinical case studies for common hearing and balance disorders, 8) treatment, including hearing aids, implantable devices, cerumen management, tinnitus, and aural rehabilitation.The exercises are comprehensive and designed so they may be solved with relatively short answers and useful for group discussion. The popular exercises from previous editions have been retained, updated, and expanded, including those on audiogram interpretation, masking, immittance, and case studies. Comprehensive answers are also included for each chapter.New to the Fourth EditionExpanded exercises on the scientific foundations from the previous edition as well as new questions added on wavelength, resonance, decibels, signal-to-noise ratio, complex vibrations, stages of transduction through the auditory system, and psychoacoustics.Many new and figures of auditory and vestibular anatomy.New exercises related to clinical topics, including preparation for patient testing, case history, wideband acoustic immittance and evoked physiologic responses.New chapter with exercises on hearing aids, assistive listening technologies, and implantable devices.Each chapter now ends with a set of multiple-choice questions. Additional multiple-choice questions are available on the companion website.
