Outcome measures
Primary outcome
SRT results of normal hearing listeners that will determine reference values.
Test-retest differences for both normal hearing and hearing impaired subjects.
Secondary outcome
Comparison of SRT scores of the Matrix test with the gold standard (LIST and VU
sentences and pure-tone audiometry), for normal hearing and hearing impaired
subjects.
The effect of mother tongue of the listener in relation to the speaker (Dutch
or Flemish)
Background summary
Speech recognition tests are powerful tools for both clinical and audiological
research. They allow us to determine patients' speech perception ability and
can help determine the potential benefits of hearing aids or cochlear implants.
Speech intelligibilty is often assessed by measuring the recognition of
sentences presented in a noisy background. Currently, two types of
sentence-in-noise tests are widely used, The first type has some limitations.
Sentences can only be used once because of training effects and sentence
structure differs between sentences, complicating comparison among languages.
Therefore another type of sentence-in-noise test, referred to as the Matrix
test, can be the solution. Each sentence is grammatically and semantically
correct and with no redundancy. The sentences are not predictable and thus can
be used indefinitely. Currently, the matrix test available in Dutch does not
meet the requierd test precision.
Study objective
The primary goal of the present study is to evaluate and validate a new Dutch
matrix test. The goal is to develop a new speech recognition test, the Matrix
test, that can be used for clinical audiology and audiological research, both
in the Netherlands and in Flanders.
Study design
It is a two-center observational study. The Dutch matrix test will be compared
with existing open-set speech tests that are commonly used in the Netherlands
(VU) and in Flanders (LIST) by conducting the tests in the same subjects. As a
reference the pure-tone audiogram will be measured. All teste will be conducted
twice.
Study burden and risks
Since this study is observational, the burden of the patient is minimal.
Several test similar or equal to those done in clinical practice will be done
during a one time visit. Although the time of visit is approximately 1 hour,
frequent breaks will be introduced.
