HearingImpaired Elderly Listeners
The Modified Rhyme Test (MRT), recorded using natural speech and two forms of synthetic speech, DECtalk and Votrax, was used to measure both open-set and closed-set speechrecognition performance. Performance of hearing-impaired elderly listeners was compared to two groups of young normal-hearing adults, one listening in quiet, and the other listening in a background of spectrally shaped noise d...
متن کاملAuditory evoked potentials to spectro-temporal modulation of complex tones in normal subjects and patients with severe brain injury.
In order to assess higher auditory processing capabilities, long-latency auditory evoked potentials (AEPs) were recorded to synthesized musical instrument tones in 22 post-comatose patients with severe brain injury causing variably attenuated behavioural responsiveness. On the basis of normative studies, three different types of spectro-temporal modulation were employed. When a continuous 'clar...
متن کاملEvaluation of evoked potentials to dyadic tones after cochlear implantation.
Auditory evoked potentials are tools widely used to assess auditory cortex functions in clinical context. However, in cochlear implant users, electrophysiological measures are challenging due to implant-created artefacts in the EEG. Here, we used independent component analysis to reduce cochlear implant-related artefacts in event-related EEGs of cochlear implant users (n = 12), which allowed de...
متن کاملAuditory evoked cortical responses to frequency glides in subjects with retrocochlear hearing impairment.
Auditory cortical responses evoked by stimulation with frequency glides of a continuous tone have been recorded from 44 subjects with intracranial tumours affecting auditory function. Response latencies obtained when stimulating the ear on the side of the tumour were different from the non-tumour ear as well as from groups with cochlear impairment and normal hearing. Tumours caused a reduction ...
متن کاملHuman cortical responses evoked by dichotically presented tones of different frequencies.
Behavioral and patient studies have suggested that during dichotic listening the ipsilateral auditory pathways are strongly inhibited, so that each hemisphere is treats the sound coming to the contralateral ear. We analysed the auditory N100m neuromagnetic evoked response following passive listening of dichotic tones of different frequencies. We found that the N100m in each hemisphere depended ...
