World of sounds (Seslerin Dünyası): A mobile auditory training game for children with cochlear implants

The aim of this study is to develop a mobile auditory training application based on gaming for children aged 3-5 years using cochlear implants and to evaluate its usability.

4 games were developed in the scope of the application World of Sounds; the crucible sound for auditory awareness, mole hunting for auditory discrimination, find the sound for auditory recognition, and choo-choo for auditory comprehension. The prototype was applied to 20 children with normal hearing and 20 children with cochlear implants, all of whom were aged 3-5. The participants were asked to fill out the Game Evaluation Form for Children. Moreover, 40 parents were included in the study, and the Evaluation Form for the Application was applied.

According to the form, at least 80% of children using cochlear implants, and all children in the healthy group, responded well to the usability factors. All factors were obtained as highly useable by parents of the children using cochlear implants. The results indicated that in the healthy group, the usefulness and motivation factors were above moderate, and the other factors were highly useable. In the mole-hunting game, there was no significant difference between the groups in the easy level of the first sub-section (p > 0.05). There was a significant difference between the groups in terms of the other sub-sections of the mole-hunting game and all sub-sections of the crucible sound, find the sound, and the choo-choo games (p < 0.05). While there was no correlation between duration of cochlear implant use and ADSI scores and the third sub-section of the crucible sound game (p > 0.05); a correlation was found in the other sub-sections of crucible sound and all sub-sections of the mole hunting, find the sound, and Choo-Choo games (p < 0.05).

It is thought that the application World of Sounds can serve as an accessible option to support traditional auditory rehabilitation for children with cochlear implants.
