Speech Perception in Children with Cochlear Implants
Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
متن کاملCochlear implants
Cochlear implants are the first example of a neural prosthesis that can substitute a sensory organ: they bypass the malfunctioning auditory periphery of profoundly-deaf people to electrically stimulate their auditory nerve. The history of cochlear implants dates back to 1957, when Djourno and Eyriès managed, for the first time, to elicit sound sensations in a deaf listener using an electrode im...
متن کاملImplications for Cochlear Implants
Amplitude envelope co-varies with F0 in Mandarin lexical tones. It can cue lexical tone perception in a tone language such as Mandarin which uses different pitch contours for phonemic contrasts. The current study investigated whether amplitude envelope could also aid the perception of lexical tones in a language such as Cantonese which uses both pitch contour and relative pitch height for phone...
متن کاملBiomaterials in cochlear implants
The cochlear implant (CI) represents, for almost 25 years now, the gold standard in the treatment of children born deaf and for postlingually deafened adults. These devices thus constitute the greatest success story in the field of 'neurobionic' prostheses. Their (now routine) fitting in adults, and especially in young children and even babies, places exacting demands on these implants, particu...
متن کاملCochlear implants and brain stem implants.
This chapter describes the development of two implantable prosthetic neurostimulators which, in the last 20 years, have revolutionised the management of severe-to-profound sensorineural deafness. We have witnessed their rapid evolution from the realms of esoteric laboratory abstraction, with many critics and little perceived clinical use, to a routine treatment which is safe, effective and, ind...
