Outcome measures
Primary outcome
The main study parameters will be changes in performance levels, eye-track
shape or length, and EEG evoked responses due to hearing impairment, aging, or
hearing device use.
Secondary outcome
The secondary outcomes are the understanding of these effects as a function of
distortion level in the audio signals and the understanding of dynamics between
different measures, as they reflect different sensory and central nervous
system processes.
Background summary
Previous research has shown that elderly and hearing impaired listeners, as
well as users of hearing aids and cochlear implants have difficulties
understanding speech in noise backgrounds. Because many hearing-impaired people
are also elderly, it is not currently known how much hearing impairment and how
much aging contribute to these difficulties. Knowing this is important to
produce more effective rehabilitation programs that are better customized for
individuals.
Study objective
The purpose of this study is to understand the complex dynamics between hearing
impairment and aging for auditory perception.
Study design
The study is an observational study, with both within-subject and across- group
comparisons. During screening age-related cognitive changes will be measured
using linguistic, working-memory, and attention tests. In all experiments the
participants will attend to audio and/or audiovisual recordings that are
processed to imitate audio distortions due to background sounds. In behavioural
experiments we will measure perception accuracy of these sounds and response
times. In physiological experiments we will measure eye tracking and EEG
signals. New audio and/or audiovisual recordings may also be collected.
Study burden and risks
There is no known risk, nor benefit associated with participation. Screening
will last 1.5 hours. The data collection will last between 3 to 8 hours per
listener, including breaks and broken into multiple sessions to minimize
fatigue and maximize alertness. Session duration and the number of sessions
will be adjusted for each participant as needed.
