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 admittance and impedance), 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 and noise canceling head phones. In addition, the authors comprehensively cover calibration of test and research equipment and stimuli used in audiology and hearing science. They also 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
“I am very glad I got an opportunity to review this book as it has helped me refresh my physics basics knowledge with pictorial representation and great examples for any non-professional to understand. In addition, this book helped me to understand the connection between physics and audiology in more depth. This is a completely updated version from the original edition with new chapters added (assistive listening devices and vestibular assessment) and a reorganization of material in a more appropriate manner.
This book contains solid, up-to-date fundamentals underlying audiologic and hearing science equipment, general physics, sound energy, AC & DC circuits, filtering & electrical impedance, analog & digital communication systems. Principles and theories underlying instrumentation are integrated with the function and clinical applications of clinical and research instrumentation specific to diagnostic audiology (acoustic immittance, audiometric testing, auditory evoked potentials testing, newborn hearing screening); rehabilitative audiology (amplification, assistive listening devices); vestibular assessment (ENG/VNG); and hearing sciences which will be very useful for recent graduates as well as for experienced Audiologists. Basic protocols for the use of instrumentation were described comprehensively, and this knowledge and understanding of audiological and hearing sciences instrumentation both facilitate and enhance successful applications of this instrumentation in our day-to-day practise.
…New to this edition are instructor PowerPoint presentations for all chapters, practical step-by-step video demonstrations, and student PowerPoint explanations of how to construct direct- and alternating-current electrical circuits, and low-pass, high-pass, and band-pass filters enhances readers understanding of concepts…
…The research tools used by hearing scientists and audiologists largely involve the same instrumentation used by audiologists for clinical and research purposes. This book can serve as a basic instrumentation text for AuD and PhD students and hearing scientists and audiologists. The authors made sure that this book is a basic reference for clinicians, educators, and researchers in audiology and hearing sciences and a tool for understanding material presented in more advanced instrumentation texts. It also can function as a supplementary text for doctoral courses in amplification. I want to conclude that the authors did a tremendous job in the making this book and will be an asset to our audiology field.”

“This book is informative, with concise explanations of basic principles of physics and technology aiding the reader in understanding how these are related to instrumentation used within audiology and scientific aspects of hearing. A valuable text to have on the shelf as a source of information for those studying or teaching in the field of audiology.
The authors have made considerable effort with the flow of information through the chapters, beginning with the general fundamentals and gradually moving to complex theories and their use, either instrumentally or clinically.
The first few chapters allow the reader to recognise the essential underlying concepts of electricity; direct, alternating current, circuitry and its components. The next few chapters concentrate on signal processing, including analogue to digital, referencing to quantisation, sampling and filtering. The latter chapters describe the functionality of various components found in different hearing aids, integrating this into instrumentation. The additional chapters on amplification, assistive devices and vestibular assessment makes this book more complete, enveloping many of the crucial branches routinely used in the field of audiology.
Each section is well written with clarity and depth explanation. The use of diagrams, some simple but effective, allow better understanding of the various concepts…
Assistive components, such as the companion website using PowerPoint and videos, allow better comprehension of the different topics.”
