Overview

Understanding the array and complexity of instrumentation available to audiologists and hearing scientists is important to students, beginning clinicians, and even seasoned professionals. The second edition of Instrumentation for Audiology and Hearing Science: Theory and Practice is a comprehensive and accessible look at instrumentation used in these fields for research and clinical purposes. The expert authors introduce the laws of physics as they relate to audiology and hearing science and explain a range of concepts in electronics directly related to instrumentation used in audiology and hearing science, such as filtering and immittance (involving acceptance i.e., admittance, and rejection i.e., impedance of energy), explain the fundamental instrumentation concepts in mathematics, physics, and electronics in a systematic manner including only the necessary formulae and basic scientific principles. This unique professional text presents the fundamentals of the evolution of communication systems from analog to digital, including such concepts as digital signals, sound resolution, sampling, quantization and their applications to current technology such as video calls, noise canceling head phones, and CD players. In addition, the authors comprehensively cover calibration of test and research equipment and stimuli used in audiology and hearing science and clearly describe elements of electronics and digital technology as they apply to our everyday lives and experiences as well as to the fields of audiology and hearing sciences. New to the Second Edition New chapters on amplification, assistive listening devices, and vestibular assessment (electronystagmography and videonystagmography), geared toward audiology and hearing science students and professionals Extensive reorganization for a smoother flow of information Expanded focus on evidence-based practice Informed by the authors' teaching, research, and clinical experiences, the original chapters have either been eliminated or completely updated to reflect current scientific and clinical theories A PluralPlus companion website with practical step-by-step PowerPoint instruction and accompanying videos for the construction of direct- and alternating-current electrical circuits, as well as the construction of high-pass, low-pass, and band-pass filters
