Spatial attention in bilateral cochlear-implant users.
Cochlear-implant (CI) users have difficulty understanding speech in the presence of interfering sounds. This study was designed to determine if binaural unmasking of speech is limited by peripheral or central encoding. Speech was presented to bilateral CI listeners using their clinical processors; unprocessed or vocoded speech was presented to normal-hearing (NH) listeners. Performance was wors...
متن کاملSpatial hearing and speech intelligibility in bilateral cochlear implant users.
OBJECTIVE The abilities to localize sounds and segregate speech from interfering sounds in a complex auditory environment were studied in a group of adults who use bilateral cochlear implants. The first aim of the study was to investigate the change in speech intelligibility under bilateral and unilateral listening modes as a function of bilateral experience during the first 6 mo of activation....
متن کاملPrecedence based speech segregation in bilateral cochlear implant users.
The precedence effect (PE) enables the perceptual dominance by a source (lead) over an echo (lag) in reverberant environments. In addition to facilitating sound localization, the PE can play an important role in spatial unmasking of speech. Listeners attending to binaural vocoder simulations with identical channel center frequencies and phase demonstrated PE-based benefits in a closed-set speec...
متن کاملDichotic speech recognition by bilateral cochlear implant users
A series of experiments was run to assess bilateral cochlear implant users’ ability to fuse information presented dichotically. Two different methods of splitting the spectral information were investigated. In the first method, the odd-index channels were presented to one ear and the evenindex channels to the other ear. In the second method, the lower frequency channels were presented to one ea...
متن کاملForward-masked spatial tuning curves in cochlear implant users.
Forward-masked psychophysical spatial tuning curves (fmSTCs) were measured in twelve cochlear-implant subjects, six using bipolar stimulation (Nucleus devices) and six using monopolar stimulation (Clarion devices). fmSTCs were measured at several probe levels on a middle electrode using a fixed-level probe stimulus and variable-level maskers. The average fmSTC slopes obtained in subjects using ...
