Outcome measures
Primary outcome
Performance on speech in noise task, pupil dilatation during listening,
concentration cortisol and alpha amylase in saliva, subjective listening efford
and scores on cognitive tasks.
Secondary outcome
n.v.t.
Background summary
A major complaint of hearing impaired people is increased mental distress and
fatigue caused by extra effort needed during listening, leading to adverse
societal effects like sick-leave. Both auditory and cognitive functions
(working memory, linguistic skills) are involved in speech comprehension. It is
unknown to what extent each of those factors contributes to listening effort.
Study objective
This project examines their relative contribution using pupil dilatation and
concentration cortisol and alpha amylase in saliva as objective measures of
mental effort and questionnaires. Young and elderly normally hearing and
hearing impaired individuals will participate. Within- and between subject
differences will be examined.
Study design
Both normally hearing and hearing impaired participants will be included.
Normally hearingparticipants will serve as controls. The groups of normally
hearing and hearing impaired participants will be matched on age. The inclusion
of both young (mean age of about 25 years) and elderly (mean age of about 65
years) participants enables the examination of the effects of age on the
measures of cognition, auditory functioning and listening effort.
Study burden and risks
Participants will perform a listening task containing background noise.
Measuring pupil dilatation and sampling of saliva are non-invasive. In addition
participants will fill out some forms. This will take 2 hours of the
participants time. This research is of no risk for the participants.
