Outcome measures
Primary outcome
Speech intelligibility in noise (signal noise ratio in dB (SNR)).
Secondary outcome
Spatial hearing (sound localisation)
Background summary
Normal-hearing listeners gain important benefits from having two ears. Users of
a Cochlear Implant (CI) achieve high levels of spoken word recognition when
speech is presented in quiet. However, they experience difficulty in the
presence of competing sounds and are poor at identifying where sounds come
from. At the moment, there is a lack of material to adequately test spatial
hearing and speech intelligibility in noise in CI users.
Recently, a new apparatus has been developed by a research group from the
University of York. This apparatus is called the 'AB-York Crescent of Sound'.
To make the apparatus applicable for the Dutch population of cochlear implant
users, the test material has been replaced by Dutch sentences
Study objective
This study aims to asess the feasibility of the Dutch version of the AB-York
Crescent of Sound in normal hearing adults and unilaterally implanted adult CI
patients.
Study design
This is a cross-sectional study that intends to gather and analyze audiometric
data obtained with a new apparatus for measuring speech in noise and spatial
hearing capabilities. All participants will be tested with the new audiometric
test set up once.
Study burden and risks
Participation in this study will take some time, but it does not carry any
risks.
