Bilateral and Binaural Hearing

Research Overview

The research group is examining the benefits of utilising bilateral hearing. Target populations include children/young adults with bilateral hearing loss using two cochlear implants or a hearing aid plus an implant, and children/young adults with unilateral hearing loss using a cochlear implant in combination with normal hearing in the other ear.

Additional work is focussed on the clinical management of children/young adults using cochlear implants, including implant candidacy, pre-operative prediction of benefit, and post-operative mapping and support.

The research team is skilled in a range of assessment procedures, including audiometric assessment, language assessments, spatial hearing tests, and objective evaluation of listening effort.
