The Effect of Anatomy-based Fitting on the Perception of Speech in Noise and Music in Single-sided Deaf Cochlear Implant Users
17 luglio 2026 aggiornato da: University Hospital, Antwerp
The present study evaluates the effect of anatomy-based fitting on speech perception in noise and music perception in newly implanted single-sided deaf (SSD) CI recipients.
Speech perception in noise will be assessed using different spatial configurations of speech and noise.
Music perception will be evaluated using objective measurements for melody, harmony, timbre and pitch and using a subjective questionnaire, the Music and Cochlear implant questionnaire (MCIQ).
Furthermore, localization and self-reported hearing benefit (HISQUI19, SSQ12) will be assessed.

HISQUI19 questionnaire
Lasso di tempo: 3 months post-activation
|
Total score and classification of self-perceived auditory benefit.
The 19 items are rated on a 7-point Likert scale ranging from always (99%) to never (1%).
To calculate the overall score the corresponding numerical value of each item (from always = 7 to never = 1) is added.
Uncompleted items and the response option "not applicable" correspond to 0 in this calculation.
A total score of less than 30, 30-59, 60-89, 90-109, and 110-133 is respectively classified as a very poor, poor, moderate, good, and very good self-perceived auditory benefit.

Total score and score in the speech, spatial and quality domain.
The 12 items of this questionnaire are rated on a visual analog scale from 0 to 10 and the overall score is calculated by taking the average of the scores of these 12 items.
For the overall score and the score on each subdomain, the score ranges between 0-10 and a higher score indicates a better outcome.
