Available in PDF, EPUB and Kindle. Book excerpt: The multiple tone pair method for the elicitation of distortion product otoacoustic emissions (DPOAEs) represents a significant improvement over the standard single tone pair method in terms of test speed. This work was aimed at determining the limitations and further utility of this method which was first introduced by Dr. D. O. Kim in 1997. Experimentation into stimulus selection demonstrated how interference caused by equipment induced distortions could be avoided by adjusting the arrangement of the stimulus tones. Also, the effect of stimulus level was observed to have negligible effect on the multiple tone pair method. Further investigation into tone pair proximity led to the conclusion that tone pairs could be placed at 4/5 of an octave separation without significant reduction of the DPOAE levels due to suppression. Finally, the four tone pair stimulus was shown to produce considerable complications due to distortion, making it infeasible for use with current instrumentation.

This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The cochlea produces recordable acoustic energy (otoacoustic emissions). These otoacoustic emissions occur spontaneously or can be evoked. Distortion-product otoacoustic emissions (DPOAEs) are produced by the intermodulation between the primary stimulus tones (f2 > f1) and occur at frequencies not present in the evoking acoustic stimuli. The 2f1-f2 DPOAE is well characterized for frequencies less than 8 kHz in humans; however, most basilar membrane measurements in animals have been made at higher frequencies. Thus, DPOAE measurements were extended to the higher frequency range of human hearing. High-frequency DPOAEs were characterized by how the DPOAE level varied with primary frequency separations (f2/f1) and stimulus levels and how the group delay estimate of the DPOAE varied with primary frequency. It was concluded that high-frequency DPOAEs continued the patterns seen for low-frequency DPOAEs, indicating that high-frequency DPOAEs are the result of the same biological process responsible for low-frequency DPOAEs.

Download or read book Otoacoustic Emissions written by Martin S. Robinette and published by Thieme. This book was released on 2011-01-01 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new edition of a best-selling text with a CD-ROM by Dr. David Kemp The new edition of the best-selling Otoacoustic Emissions: Clinical Applications provides a thorough review of the complex physiology of the ear and clinical applications of the latest research on otoacoustic emissions. The book features new chapters on such important topics as middle ear function enhanced by reflectance measurements and the use of otoacoustic emissions as a preclinical measure of susceptibility to hearing loss. Accompanying the book is a CD-ROM developed by Dr. David Kemp, Ph.D., which contains animations, movies, and interviews. The CD-ROM serves as an indispensable aid to both teaching and reviewing key concepts. From physiological phenomena to diagnostic and clinical applications, this book is a complete reference on otoacoustic emissions that will provide graduates in audiology and residents in otolaryngology and otology with all the essential information needed for research and professional practice.

This book was released on 2007-12-20 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Biophysics of the Cochlea written by Anthony W. Gummer and published by World Scientific. This book was released on 2003 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of an intenational hearing-research conference held in Germany 2002. The conference brought together experts in genetics, molecular and cellular biology, physiology, engineering, physics, mathematics, audiology and medicine to synthesize and extend our understanding of how the cochlea works. Topics are discussed experimentally and theoretically at the molecular, cellular and whole-organ levels. Some of the topics are: mechanosensitivity of motor proteins; mechanochemical transduction by motor proteins; mechanoelectrical transduction in the stereocilia of hair cells; electromechanical transduction in the stereocilia, soma and synapses of hair cells; multidimensional vibration of the organ of Corti; and otoacoustic emissions. This book will be invaluable to researchers and students in auditory science. Contents: Stereocilia; Hair Cells; Whole-Organ Mechanics; Cochlear Models; Emissions; Comments and Discussions. Readership: Hearing scientists (including medical persons in otolaryngology), biophysicists and molecular' biologists, engineers interested in manufacturing silicon devices (MEMS), and persons interested in modelling biological systems.
