Strengthening the Ear-to-brain Connection in Older Adults With Hearing Loss Through Engaging Web-based Gamified Auditory-cognitive Dual-task Training: a Randomized Controlled Trial
Sponsor: The Hong Kong Polytechnic University
Summary
Abstract Objectives To assess the effectiveness of a web-based gamified auditory-cognitive dual-task training (ACDT) in improving the everyday listening abilities of older adults with hearing loss (HL), including speech perception performance, cognition, and self-reported hearing. Hypothesis to be tested ACDT participants will show significantly greater improvements in 1) self-reported hearing; 2) speech perception-in-noise; 3) attention; 4) reasoning; and 5) dual-task of listening and working memory compared to the control group at week 6, immediately post-intervention, and week 24. Design and subjects A prospective, single-blinded, two-arm parallel randomized controlled trial with individual semi-structured interviews. 164 Chinese adults aged 60 years or older, who speak Cantonese or Putonghua, and have mild-to-moderate HL with a pure-tone average of 20-50 dB across octave frequencies 0.5 to 4kHz in both ears. Study instruments A web-based gamified auditory-cognitive dual-task training. Interventions This is a 12-week program conducted five times a week, with each session lasting 60 minutes, following a sequential dual-task training design. Each session includes auditory training in speech-in-noise, rapid speech, and competing speaker, and cognitive training focusing on executive function, perceptual-motor ability, memory, and complex attention. Main outcome measures Self-reported hearing (untrained); Speech perception in noise (trained), attention in listening and sustained selective attention (trained), reasoning (trained), and dual-task of listening and working memory; complex span working memory (trained). Data analysis Descriptive statistics, an independent sample t-test or chi square test, generalized estimating equation and thematic analysis will be used. Expected results ACDT significantly improves the everyday listening abilities of older adults with HL.

Interventions
Web-based gamified auditory-cognitive sequential dual-task training system
The intervention is a 12-week sequential dual-task training program delivered five times per week for 60 minutes per session. Each session includes 5 minutes of volume adjustment and orientation exercises, 25 minutes of adaptive auditory training in speech-in-noise, rapid speech, and competing-speaker listening, 25 minutes of culturally tailored cognitive games targeting executive function, memory, attention, and perceptual-motor skills, and a 5-minute wrap-up with communication strategies and long-term memory recall. The program uses real-life scenarios, individualized difficulty adjustment, audiovisual guidance, and gamified features such as praise, fireworks, likes, and leaderboards to enhance engagement.
Control
Participants will be instructed to complete web-based Chinese crossword puzzles 60 minutes per day and five days a week. Medium difficulty level will be selected for participants according to previous research.
