The Auditory Periphery: Biophysics and Physiology is an attempt to provide comprehensive and detailed information regarding biophysics and physiology in terms of the peripheral auditory system. Eight detailed chapters are presented in the book where the first and last serve as introduction and summary. The introductory chapter provides background on the anatomy and functional organization of the auditory system. The second chapter illustrates the most common experimental techniques. A whole chapter is dedicated to the discussion of the middle ear, while Chapters 4 and 5 discuss cochlear mechanisms and potentials. The topic most studied but less understood in the operation of the ear is also emphasized in the book, which is the production of distortion. The topic of feedback mechanisms and systems is also covered. This book aims to be of help to various specialists such as biophysicists, bioengineers, physiologists, otolaryngologists, and speech and hearing scientists.
