Abstract
There were 12 boys and 15 girls. The average hearing loss in the better ear was 104 dBHL, range from 83-117 dBHL, SD = 8.33. The mean age of enrollment was 2 years and 10 months. The majority gradually developed listening skills and speaking ability. There was no relationship between age of enrollme...

Abstract
Over the last years, indications for cochlear implants (CIs) have changed dramatically. The benefits depend on the preconditions of the individual patient as well as on the subsequent (re)habilitation. Therefore, many variables influencing the hearing and speech perception of a CI user must be kept...

Abstract
The technique of cochlear implantation was the first method which allowed replacement of a sense organ by a (partially) implantable electronic prosthesis. By this method the cells of the spiral ganglion of the cochlea are directly stimulated by the electrodes introduced into the cochlea, bypassing t...

Abstract
The radiologic evaluation of the temporal bone in cochlear implant candidates can detect malformations of the inner ear in up to 20% of cases. The aim of our study was to analyze and classify malformations of the inner ear in patients with cochlear implants carried out from 2001 to 2009. Malformatio...

Abstract
A new approach to the separation of speech from speech-in-noise mixtures is the use of time-frequency (T-F) masking. Originated in the field of computational auditory scene analysis, T-F masking performs separation in the time-frequency domain. This article introduces the T-F masking concept and rev...

Dual sensory impairment (DSI) refers to the presence of both hearing loss and vision loss. The occurrence of DSI is particularly prevalent among the aging population, with studies showing between 9% and 21% of adults older than 70 years having some degree of DSI. Despite this, there is little direct...
