Noisy listening conditions remain challenging for most cochlear implant patients. The present study simulated the effects of decay rates of excitation spread in cochlear implants on the intelligibility of Mandarin speech in noise. Mandarin sentence and tone stimuli were processed by noise-vocoder, and presented to normal-hearing listeners for identification. The decay rates of excitation spread...

In this paper we explore the possibility of using a recently discovered form of stochastic resonance termed suprathreshold stochastic resonance to improve speech comprehension in patients fitted with cochlear implants. A leaky-integrate-and-fire (LIF) neurone is used to model cochlear nerve activity when subject to electrical stimulation. This model, in principle, captures key aspects of tempor...

This article reports the relationships between a large number of child and family related factors and children’s functional outcomes, according to parental report, in the domains of spoken language communication, social skills and participation, academic achievement, and independence and identity, through a series of step-wise regression analyses. Parents of 247 children who had received cochle...

Several million Americans today have profound hearing loss, and for years they had to rely on conventional hearing aids. Although hearing aids have been found to benefit hearing impaired individuals who suffer mild to moderate deafness, they do not seem to provide much benefit to individuals with profound (sensorineural) deafness. Today, a prosthetic device, a cochlear implant, can be implanted...

Cochlear implants provide individuals who are deaf with access to speech. Although substantial advancements have been made by novel technologies, there still is high variability in language development during childhood, depending on adaptation and neural plasticity. These factors have often been investigated in the auditory domain, with the mismatch negativity as an index for sensory and phonol...

Radiologic assessment of cochlear implants can be limited because of metallic streak artifacts and the high attenuation of the temporal bones. We report on 14 patients with 18 cochlear implants (17 Med-El standard 31.5-mm arrays, 1 Med-El medium 24-mm array) who underwent flat panel CT with the use of high-resolution secondary reconstruction techniques. Flat panel CT depicted the insertion site...

OBJECTIVE To examine spoken language outcomes in children undergoing bilateral cochlear implantation compared with matched peers undergoing unilateral implantation. DESIGN Case-control, frequency-matched, retrospective cross-sectional multicenter study. SETTING Two Belgian and 3 Dutch cochlear implantation centers. PARTICIPANTS Twenty-five children with 1 cochlear implant matched with 25 ...

Cochlear Implants are widely accepted prosthetic devices that improve the hearing ability of people with profound hearing loss. The cochlear implant speech processor is responsible for decomposing the input sound into different frequency bands and delivering the most appropriate pattern to the electrodes. The performance of the cochlear prostheses depends on various parameters such as number of...

This Australian study examined the communication, academic, and social outcomes of pediatric cochlear implantation from the perspectives of teachers working with children with cochlear implants. The children were aged from 1 to 18 years and attended a range of educational settings in early intervention, primary, and secondary schooling. One hundred and fifty-one teachers completed a survey on o...
