Partial deafness cochlear implantation (PDCI) and electric-acoustic stimulation (EAS).
The purposes of this paper are to (1) review briefly the experience to date with combined EAS for patients with some residual, low-frequency hearing; and (2) describe the further results that have been obtained with this combination for patients with higher levels of residual hearing at low frequencies, termed 'PDCI'. In broad terms, PDCI and combined EAS have produced large improvements in the...
متن کاملCochlear dead regions constrain the benefit of combining acoustic stimulation with electric stimulation.
OBJECTIVE The aims of this study were to (1) detect the presence and edge frequency (fe) of a cochlear dead region in the ear with residual acoustic hearing for bimodal cochlear implant users, and (2) determine whether amplification based on the presence or absence of a dead region would improve speech understanding and sound quality. DESIGN Twenty-two listeners with a cochlear implant in one...
متن کاملElectric acoustic stimulation in children.
BACKGROUND/AIMS The combined electric acoustic stimulation (EAS) of one ear is a topic that has received considerable attention over the last 10 years, the technique having originally been introduced by Prof. Christoph A. von Ilberg for so-called borderline adult cochlear implant (CI) candidates. Its development has followed several parallel strands, including the modification of existing surgi...
متن کاملPhysiological Mechanisms in Combined Electric-Acoustic Stimulation.
OBJECTIVE Electrical stimulation is normally performed on ears that have no hearing function, i.e., lack functional hair cells. The properties of electrically-evoked responses in these cochleae were investigated in several previous studies. Recent clinical developments have introduced cochlear implantation (CI) in residually-hearing ears to improve speech understanding in noise. The present stu...
متن کاملLoudness balance between electric and acoustic stimulation.
Binaural loudness balance between electric and acoustic stimulation is obtained in auditory brainstem implant listeners who had substantial acoustic hearing in one ear. The data are well described by a linear relationship between acoustic decibels and electric microamps. Based upon this linear relationship, we propose an exponential model of loudness growth in electric stimulation. The exponent...
