Application of Multi-Tonal Complex with Optical Coherence Tomography Imaging System for Vibrometric Analysis of Inner-Ear Structures
MetadataShow full item record
Currently, research is being conducted on single tone sound transduction within the auditory portion of the inner ear, the cochlea . The study of cochlear mechanics in large rodents has provided important insight into cochlear function . Additionally, multi-tone stimuli can provide a new perspective in vibrometric analyses that could be used in audiometry as a measure of hearing loss for patients in terms of both magnitude and their unique frequency envelope. Therefore, the proposed study was aimed to test the recent implementation of multitone calibration into an existing python program, PyVib2, which was used during Optical Coherence Tomography (OCT) imaging experiments for vibrometric analysis of the structures in the inner-ear. Within PyVib2, the multi-tone stimulus program will be executed in conjunction with the OCT M-scan program for full vibrometric analysis. This research resulted in the further development of the PyVib2 program, the acquisition of insightful image data of structures of the human inner-ear, which was collected using the OCT imaging system, and the verification of extracting the vibratory response of these structures when subjected to a multi-tone stimuli.
