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
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.

Inclusion Criteria:
- Ethnic Chinese aged 60 years and above, who speak Cantonese or Putonghua;
- Mild-to-moderate peripheral hearing loss diagnosed by a pure-tone average of 20-50 dB across octave frequencies of 0.5-4kHz in both ears;
- Not using hearing aids;
- Sensorineural hearing loss (defined as an air-bone gap across 0.5, 1, and 2 kHz<15 dB); and 5) No cognitive impairment [score of ≦2 on the 5-item Abbreviated Memory Inventory for the Chinese (AMIC)].
Exclusion Criteria:

Kísérleti: A web-based gamified auditory-cognitive sequential dual-task training
A web-based gamified auditory-cognitive sequential dual-task training (ACDT) will be provided to participants.
Each participant will receive a 12-week program conducted five times a week, with each session lasting 60 minutes, following a sequential dual-task training design.
|
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.

The Cantonese Hearing in Noise Test
Időkeret: at week 6, immediately post-intervention (week 12), and week 24
|
a standardized Cantonese sentence speech-intelligibility test, assesses speech reception thresholds for sentences in quiet and in spatially simulated noise presented from the front, right, or left.
It has demonstrated low within-list response variability and high inter-list reliability, with normative results comparable to those of the English Hearing in Noise Test.

The Chinese Auditory Verbal Learning Test
Időkeret: at week 6, immediately post-intervention (week 12), and week 24
|
The Chinese Auditory Verbal Learning Test (AVLT), which assesses multiple cognitive domains including immediate recall, learning efficiency, delayed recall, retention rate, and recognition memory, and has demonstrated high test-retest reliability (ICC=0.79-0.82)
and 78% sensitivity;

The Chinese Trial Making Test Part A& B
Időkeret: at week 6, immediately post-intervention (week 12), and week 24
|
The Chinese Trial Making Test Part A& B (TMT A&B), which measures visual attention, processing speed, and executive function, and has shown strong discriminant validity (d=1.2 for vascular dementia)
|
at week 6, immediately post-intervention (week 12), and week 24
|
|
Dual task of listening and working memory
Időkeret: at week 6, immediately post-intervention (week 12), and week 24
|
complex span working memory (trained): Participants are shown a string of five digits for 5 seconds to memorize for later recall.
They then hear a list of five AB isophonemic monosyllabic CVC words (e.g., ship, rug, rail) in ICRA 6-talker babble at a 0 dB signal-to-noise ratio and must repeat each word immediately.
After each word list, they recall the five digits.
