Outcome measures
Primary outcome
The Speech Reception Threshold (SRT) for various performances (scores). They
are compared between different noise conditions and across subjects (hearing
impaired and normal hearing subjects).
Secondary outcome
-
Background summary
Many hearing impaired people suffer from understanding speech in background
noise. Hearing aids become ever more advanced. Except from amplifying the
incoming sounds, the devices also perform advanced signal processing. In many
studies the effects and consequences of advanced signal processing are
investigated because they are not always clear. In this study, the effect on
speech intelligibility is investigated for various kinds of background noise
and for different types of sound processing.
Study objective
The results are used to develop a computer model that can predict speech
intelligibility for hearing impaired people, even after signal processing. A
model like that can be used to choose the most optimal hearing aid settings in
the future. Furthermore, a computer model could replace long term listening
experiments. The results of this study are also used to gain more insight about
speech perception and about how the hearing functions. In addition, they will
be used to educate hearing impaired people.
Study design
An observational study with hearing impaired and normal hearing subjects.
Study burden and risks
Two times a visit of three hours at the AMC. There are no risks, but to keep
the load as small as possible, the measurement is frequently paused.
