Research on Effective Methodology for Hearing Impairment Rehabilitation; Based on a Diary Study for Elderly OnlineAuditory Training

Abstract

This study analyzes the utilization of online-based auditory training content by individuals aged 70 and above, who are the primary users of auditory training programs. Additionally, we explore effective methodologies for online-based auditory training programs by investigating the impact of differences in auditory training content on training outcomes. Two elderly individuals, one female and one male, wearing hearing aids, participated in this study. We assessed speech perception in noise at 5 dB SNR before and after auditory training. They completed a listening effort questionnaire and attended a total of 20 auditory training sessions over 7 weeks. During the training period, they maintained a “training diary” three times a week. We conducted interviews with the two audiologists who provided auditory training to objectively analyze the diary survey results. Both hearing aid users demonstrated improved speech perception in noise scores and reduced listening effort. The analysis of auditory training experiences categorized them into three types: ‘emotion-stimulating,’ ‘information-generating,’ and ‘participatory.’ These categories informed the development of strategies for online auditory training content, including: 1) personalized auditory training content using artificial intelligence, 2) integration of auditory training into senior education programs, and 3) creation of interactive online auditory rehabilitation content using bidirectional technology. The study emphasizes the need for continuous development of interactive content tailored to the demographic and lifestyle characteristics of the participants. In the context of online-based auditory training, individualized programs, such as group training and professional-led programs, are essential. Further studies are required to determine whether training outcomes can be enhanced through experience-based content.
