项目摘要
The proposed research aims to combine the areas of speech understanding, binaural hearing, sound
localization, and cochlear implants (CIs). The proposed research Is novel because it aims to understand the
advantages, capabilities, and limitations of bilateral CIs under controlled multi-electrode stimulation and of
more "realistic" auditory stiniuli that are modulated in time. Controlled multi-electrode stimulation research
and research on binaural modulated stimuli has only started recently. Research on this topic Is a logical next
|step in bilateral CI researx;h; moving to less controlled and more complex auditory stimuli. It would help
provide understanding of an important advantage of bilateral Implantation, that of understanding speech in
noisy environments.
the main hypothesis driving this work Is that current CI systems introduce fundamental differences from
[the Wealthy auditory system, and these differences alter important acoustic information enough to
significantly diminish any binaural hearing advantage. These differences include, but are not limited to:
interjaural tonotopic place mismatch, unequal interaural neural survival, varying loudness growth between
indi\>idual electrodes and ears, channel interactions, partial or complete lack of interaural sound fusion, and
lack;of travelling wave of an acoustic stimulus along the basilar membrane. Some of these limitations may be
compensated by different processing schemes or changes to the physical devices. Other limitations are
intrinsic to electrical stimulation and cannot be compensated with the current generation of CIs. The
mentored phase of the proposed research focused on single-electrode binaural signal detection and sound
localization. The independent phase of the proposed research will focus on multi-electrode binaural signal
[detection, sound localization, and understanding speech in realistic listening environments. The ultimate aim
is to provide a binaural advantage to bilateral CI users' ability to localize sounds and to understand speech in
difficult listening environments, like noisy or reverberant rooms. This research has potential to guide the
clinical implementation of a Unlfonn method of bilateral fitting of CIs.
本研究旨在结合言语理解、双耳听力、声音等领域
