Enhancing Communication Ability in Hearing Aid Users: Preliminary Case Study of A Hybrid Auditory Training Approach

Abstract

Auditory training programs aim to improve speech perception and communication skills in hearing aid users. Despite the effectiveness of traditional face-to-face training, logistical challenges hinder its widespread adoption. To overcome these barriers, hybrid auditory training, integrating face-to-face and self-administered sessions at home, has emerged as a potential solution. This study evaluates the efficacy of a hybrid auditory training program in enhancing communication abilities among hearing aid users. Six participants engaged in a 10-session hybrid auditory training program, comprising five face-to-face sessions conducted by professionals and five self-administered sessions at home, either independently or with family members. Training activities focused on listening to sentences with and without noise, and one and two-syllable words in noise-free conditions. Standardized assessments, including the Korean version of the matrix test, modified client-oriented scale inventory, and International Outcome Inventory-Alternative Interventions, were utilized to assess speech perception, and self-reported communication abilities. Pre- and post-training assessments demonstrated significant enhancements in speech perception in noise across various signal-to-noise ratios (0-, 5-, and 10-dB signal to noise ratio). Participants reported a slight improvement in communication ability and expressed satisfaction with their participation. The study suggests that hybrid auditory training effectively enhances communication abilities in hearing aid users, akin to traditional face-to-face methods. The hybrid approach offers flexibility and accessibility, addressing logistical challenges. Further research should explore and compare various auditory training modalities to develop tailored interventions for individuals with hearing impairments.
