The third edition of ''Audiology Workbook'' is composed of an abundance of questions and activities designed as a means for undergraduate and beginning graduate students to reinforce their knowledge of concepts and procedures covered in introductory hearing science and clinical audiology courses. This third edition of ''Audiology Workbook'' is an appropriate supplement to any introductory audiology textbook and/or class lectures, and focuses on exercises and questions that are beneficial for any traditional audiology undergraduate or beginning AuD course in hearing science and audiology principles and procedures. The ''Audiology Workbook'' includes activities such as drawing and labeling diagrams, drawing waveforms, calculating frequencies/periods, amplitudes, and phases, interpreting audiograms, speech tests, tympanograms, acoustic reflexes, and auditory brainstem responses. There are also questions to reinforce knowledge about hearing disorders, as well as basic understanding of hearing aids and their fittings. Activities are comprehensive and designed so that they may be solved with relatively short answers and useful for group discussion. The ''Audiology Workbook'' has been extensively revised from the previous edition. This edition updates, expands, and reorganizes material from previous editions, but retains the features that worked well, including detailed answers for all of the exercises. More exercises have been added in traditionally difficult areas such as properties of sound, anatomy/physiology, audiogram interpretation/description, and masking. In addition, there are now separate chapters on immittance, OAEs and ABRs, as well as a chapter on the vestibular system and its assessment. New to this edition is a separate chapter on vestibular anatomy, physiology, disorders, and assessments for those who wish to learn more about this area of audiology. The popular case studies have been revised into a more consistent format with answers written similar to how they might be done in a clinical audiology report. There are exercises designed to reinforce knowledge of auditory disorders, and a chapter entirely devoted to case studies in order to help students learn how to integrate basic diagnostic test results and relate them to a variety of hearing disorders.
