Effect of stimulation levels on speech recognition and auditory threshold performance

When programming a Cochlear® device, two measurements are normally assessed. T levels relate to the quietest sound the CI user can hear i.e. thresholds, and C levels are comfortable levels which are tolerable for the CI user. If these levels...

Auditory deprivation and single-sided deafness

In cases of bilateral auditory deprivation, there is clear evidence of an inverse relationship between performance after cochlear implantation and the length of severe to profound deafness prior to implantation (i.e. the longer the deprivation the poorer the outcome on...

Effects of age on neuro-physiological processing of speech at brainstem level

Degenerative changes associated with ageing may affect processing of spectral and temporal cues in speech at cortical and subcortical levels, even though these individuals may have normal audiometric thresholds. These changes are more likely to be picked up by speech...
