Feasibility and Efficacy Study of an Integrated Computer-Based Auditory Training Program (MalGui) in Newly Fitted Hearing Aid Users

Purpose This study evaluated the clinical feasibility and effectiveness of a newly developed computer-based auditory training (CBAT) program, “Malgui”, which integrates multiple training tools previously validated in independent studies, when applied to newly fitted hearing aid users. Methods Fourteen adult participants with sensorineural hearing loss were recruited, of whom 12 completed the study. All participants were in the first month of hearing aid use. The CBAT program incorporated diverse evidence-based tasks, including speech-in-noise sentence recognition, order sequencing, and story-based listening exercises, delivered over 10 sessions across 5 weeks. Objective measures included the Korean digit-in-noise (K-DIN) test, Korean repeat and recall test (K-RRT), and brief test of cognitive-communication disorders (BCCD). Subjective satisfaction was assessed using a Likert scale survey, and compliance was monitored via training log data. Assessments were conducted at baseline, immediately after training and 1 month after training completion. Results Auditory training significantly improved speech-in-noise perception (K-DIN, p = 0.017; K-RRT, p = 0.009). BCCD also showed significant gains across cognitive, communicative, and total domains (all p < 0.001). Importantly, retention effects were observed, with performance at 1-month follow-up surpassing immediate post-training levels. Compliance was high, with 86% of participants completing all sessions, and subjective satisfaction ratings were predominantly positive. Conclusion The Malgui CBAT program, which consolidates multiple evidence-based training tools into a single integrated platform, demonstrated clinical benefit for newly fitted hearing aid users. It yielded significant improvements in speech-in-noise intelligibility, cognitive-communication function, and user satisfaction, with sustained effects beyond the training period.
