A channel-selection criterion for suppressing reverberation in cochlear implants.
Little is known about the extent to which reverberation affects speech intelligibility by cochlear implant (CI) listeners. Experiment 1 assessed CI users' performance using Institute of Electrical and Electronics Engineers (IEEE) sentences corrupted with varying degrees of reverberation. Reverberation times of 0.30, 0.60, 0.80, and 1.0 s were used. Results indicated that for all subjects tested...
متن کاملSimultaneous suppression of noise and reverberation in cochlear implants using a ratio masking strategy.
Cochlear implant (CI) recipients' ability to identify words is reduced in noisy or reverberant environments. The speech identification task for CI users becomes even more challenging in conditions where both reverberation and noise co-exist as they mask the spectro-temporal cues of speech in a rather complementary fashion. Ideal channel selection (ICS) was found to result in significantly more ...
متن کاملStudy and Comparison of Formant Characteristics of Persian Vowels in 4-7-year-old Children Using Cochlear Implants and Those Using Hearing Aids
Background and Objective: One of the most important physical properties of vowels is their formant structure. One of the most obvious speech errors in hearing-impaired children is vowel errors. The present study aimed to determine and compare the formant structure of Persian vowels in deaf and cochlear implant children in the age range of 4-7 years. Materials and Methods: This descriptive-anal...
متن کاملEffects of noise and reverberation on virtual sound localization for listeners with bilateral cochlear implants.
OBJECTIVE This study investigated the effects of both noise and reverberation on the ability of listeners with bilateral cochlear implants (BCIs) to localize and the feasibility of using a virtual localization test to evaluate BCI users. DESIGN Seven adults with normal hearing (NH) and two adults with BCIs participated. All subjects completed the virtual localization test in quiet and at 0, -...
متن کاملComparison of Auditory Perception in Cochlear Implanted Children with and without Additional Disabilities
Background: The number of children with cochlear implants who have other difficulties such as attention deficiency and cerebral palsy has increased dramatically. Despite the need for information on the results of cochlear implantation in this group, the available literature is extremely limited. We, therefore, sought to compare the levels of auditory perception in children with cochlear implant...
