Abstract

Background: The objective of this study was to evaluate the effect of "Spatially separated speech in noise" auditory training on the ability of speech perception in noise among bimodal fitting users. The assumption was that the rehabilitation can enhance spatial hearing and hence speech in noise perception. This study was an interventional study, with a pre/post-design. Speech recognition ability was assessed with the specific tests. After performing the rehabilitation stages in the intervention group, the speech tests were again implemented, and by comparing the pre- and post-intervention data, the effect of auditory training on the speech abilities was assessed. Twenty-four children of 8-12 years who had undergone cochlear implantation and continuously used bimodal fitting were investigated in two groups of control and intervention. Results: The results showed a significant difference between the groups in different speech tests after the intervention, which indicated that the intervention group have improved more than the control group. Conclusion: It can be concluded that "Spatially separated speech in noise" auditory training can improve the speech perception in noise in bimodal fitting users. In general, this rehabilitation method is useful for enhancing the speech in noise perception ability.
