Hearing Science Fundamentals, Third Edition introduces the basic concepts in hearing science in an easy-to-understand format for undergraduate and graduate level students. This textbook includes a wide variety of student-friendly features designed to facilitate learning, as well as instructor resources for seamless integration to the course. The text is divided into four clear sections to cover everything from the physics of sound to the anatomy and physiology of the auditory pathway and beyond. The textbook begins by delving into the basics of acoustics and digital signal processing (DSP). In the next section, readers will find full coverage of the basic anatomy and physiology of the auditory mechanism. The third section contains eight chapters on psychoacoustics and how sound is perceived via the auditory pathways. The final section discusses pathologies of the auditory mechanisms. Multiple disorders from each portion of the auditory system are described in detail. These chapters are intended to provide an introduction to auditory pathologies to support future coursework in audiology and related fields.
