Efficacy of a newly developed auditory-cognitive training system on speech recognition, central auditory processing and cognitive ability among older adults with normal cognition and with neurocognitive impairment.

Aim: To evaluate the efficacy of a newly developed auditory-cognitive training system on speech recognition, central auditory processing and cognition among older adults with normal cognition (NC) and with neurocognitive impairment (NCI).

Methods: A double-blind quasi-experiment was carried out on NC (n = 43) and NCI (n = 33) groups. Participants in each group were randomly assigned into treatment and control programs groups.

Relative contributions of auditory and cognitive functions on speech recognition in quiet and in noise among older adults.

Introduction: Hearing acuity, central auditory processing and cognition contribute to the speech recognition difficulty experienced by older adults. Therefore, quantifying the contribution of these factors on speech recognition problem is important in order to formulate a holistic and effective rehabilitation.

Objective: To examine the relative contributions of auditory functioning and cognition status to speech recognition in quiet and in noise.

Long-term electrode impedance changes and failure prevalence in cochlear implants.

Objective: This study assessed the prevalence of electrode failures and electrode impedance measures in Nucleus cochlear implants around initial activation (an average of 16 days after surgery) and after 8 to 12 years of device use.

Design: Retrospective data from the Melbourne Cochlear Implant Clinic was collated and analysed.

Study Sample: Included in this study were 232 adults, all of whom were implanted at the clinic between March 1998 and August 2005.
