Sequential stream segregation in normally-hearing and cochlear-implant listenersa)
Sequential stream segregation by normal hearing (NH) and cochlear implant (CI) listeners was investigated using an irregular rhythm detection (IRD) task. Pure tones and narrowband noises of different bandwidths were presented monaurally to older and younger NH listeners via headphones. For CI users, stimuli were delivered as pure tones via soundfield and via direct electrical stimulation. Resul...
متن کاملAuditory stream segregation in cochlear implant listeners: measures based on temporal discrimination and interleaved melody recognition.
The evidence that cochlear implant listeners routinely experience stream segregation is limited and equivocal. Streaming in these listeners was explored using tone sequences matched to the center frequencies of the implant's 22 electrodes. Experiment 1 measured temporal discrimination for short (ABA triplet) and longer (12 AB cycles) sequences (tone/silence durations = 60/40 ms). Tone A stimula...
متن کاملStream segregation on a single electrode as a function of pulse rate in cochlear implant listeners.
While cochlear implants (CIs) usually provide high levels of speech recognition in quiet, speech recognition in noise remains challenging. To overcome these difficulties, it is important to understand how implanted listeners separate a target signal from interferers. Stream segregation has been studied extensively in both normal and electric hearing, as a function of place of stimulation. Howev...
متن کاملSpectral peak resolution and speech recognition in quiet: normal hearing, hearing impaired, and cochlear implant listeners.
Spectral peak resolution was investigated in normal hearing (NH), hearing impaired (HI), and cochlear implant (CI) listeners. The task involved discriminating between two rippled noise stimuli in which the frequency positions of the log-spaced peaks and valleys were interchanged. The ripple spacing was varied adaptively from 0.13 to 11.31 ripples/octave, and the minimum ripple spacing at which ...
متن کاملAuditory Perception and Verbal Intelligibility in Children with Cochlear Implant, Hearing Aids and Normal Hearing
Objective: The aim of the present research was to compare the auditory perception and verbal intelligibility in children with cochlear implant, hearing aids and normal hearing. Methods: 60 children aged 5-7 years were divided to three groups and each group contained 20 children. The first and second groups were selected ordinarily from children with cochlear implant and hearing aids by conve...
