The cochlea does not just pick up sound, it also produces sounds of low intensity called Otoacoustic Emissions (OAEs). Sounds produced by healthy ears - either spontaneously or in response to stimuli - allow researchers and clinicians to study hearing and cochlear function noninvasively in both animals and humans. This book presents the first serious review of the biological basis of these otoacoustic emissions.
Sounds that are produced by healthy ears allow researchers and clinicians to study hearing and cochlear function non-invasively in both animals and humans. Active processes, such as those in hair cells that produce emissions, represent a burgeoning and important area of sensory research. This book presents the first serious review of the biological basis of these otoacoustic emissions. It provides a basis for understanding how and why otoacoustic emissions testing works using a basic understanding of general hearing processes. The book is of interest to clinicians, particularly otolaryngologists and audiologists.
