Tobias Rader
Speech Perception of Cochlear Implanted Patients with Combined Electric-Acoustic Stimulation

90 Seiten, Dissertation Technische Universität München (2012), Hardcover, B5

Zusammenfassung / Abstract

Electric-Acoustic Stimulation (EAS) means the stimulation of the hearing nerve with an inner ear hearing prosthesis by electrical pulses to compensate high frequency deafness, and in parallel using the low frequency residual hearing by a hearing aid at the same ear. The “Multi-Source Noise Field” is developed and realized as examination environment for the subsequent realistic measurement of speech perception

levels in various noisy situations. The transition frequency from acoustic to electric stimulation is determined by psycho-acoustic pitch comparison tests. The results of measurements from patients with inner ear hearing prosthesis have been reproduced by simulations with normal hearing persons and described by a model.
