Predicting the Intelligibility of Cochlear-implant Vocoded Speech from Objective Quality Measure(1) Department of Electrical Engineering, The University of Texas at Dallas, Richardson, Texas75083, USA Chairman:Hung-Chi Yang Presenter: Yu-Kai Wang Advisor: Dr. Yeou-Jiunn Chen Date: 2012.12.12 Outline Introduction Purposes Material and Methods Results Conclusions Introduction(1) Cochlear implants (CIs) Restore partial hearing to patients with severe to profound deafness. A number of factors may affect performance. Electrode insertion depth and placement Quiet and noisy conditions Electric-acoustic stimulation (EAS) An electrode array It is implanted only partially into the cochlea so as to preserve the residual acoustic hearing . (20-60 dB hearing loss (HL) up to 750 Hz and severe-to-profound hearing loss at 1000 Hz and above)
