PhD

Affiliate Investigator, BC Children's Hospital

Dr. Sladen studies hearing and hearing loss in children. The majority of his work is in the area of cochlear implants; a device used to manage severe hearing loss. Dr. Sladen’s recent work has examined children with severe unilateral hearing loss (single-sided deafness) and their outcomes following cochlear implantation. Dr. Sladen has also been exploring the use of virtual reality test environments to assess various auditory skills such as speech understanding in noise and sound source localization.

Cochlear Implantation for Single-Sided Deafness

Children with severe unilateral hearing loss (single-sided deafness) have difficulty with complex auditory tasks such as understanding speech in noise and locating sound sources. Compared to children with typical hearing, children with SSD have lower speech and language scores and are at risk for academic failure. Recently, cochlear implants have been made available to children and adults who have severe-to-profound hearing loss in one ear only (single-sided deafness). My current work examines the outcomes for this population. Specifically, my studies examine how well the implant restores speech understanding to the implanted side, the ability to understand speech when listening in background noise, and the ability to locate sound sources.

Gamified Auditory Training to Improve Speech Understanding in Noise and Localization Among Children with Cochlear Implants

Tablet based games can be used in auditory training for children who use cochlear implants. In this study we are examining how much improvement is observed following a 4-week training period.

Assessment of Auditory Function within Virtual Reality Test Environments

In this study we are testing speech understanding in noise and sound source localization using a virtual reality test system. Our overall aim is to measure auditory function using quasi-realistic measures to gain further insight into the auditory abilities of children during their everyday lives.
