NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
The Methods and Effectiveness of Auditory-Cognitive Training for Older Adults: A Mixed Evidence Synthesis
ABSTRACT
Background:
Auditory-cognitive training (ACT) combines auditory and cognitive exercises to improve listening and cognition in individuals with hearing difficulties, yet lacks standardized implementation and consistent evidence.
Objective:
This mixed evidence synthesis aimed to map ACT’s implementation characteristics and summarize its reported short-term and maintenance effects on trained and non-trained cognitive and auditory outcomes, including hearing functioning in daily life.
Methods:
We carried out a systematic search including Embase, Cochrane Library, PubMed, and APA PsycNet from inception to January 15, 2026. Studies evaluating integrated auditory–cognitive training interventions in older adults were included, covering RCTs, quasi-experimental, and pre–post intervention designs, with 12 articles included. Meta-analysis was restricted to RCTs with sufficient available data.
Results:
Results showed that ACT yields significant short-term improvements in speech-in-noise (SIN) recognition (SMD = −0.25, 95% CI: −0.47 to −0.04, p = 0.02) and memory (SMD = 1.02, 95% CI: 0.53 to 1.51, p < 0.001). The SIN improvement (0.25 dB) is modest and below clinical meaningfulness. Effects on pure-tone audiometry, subjective hearing function, attention, working memory, executive function, and global cognition were limited and nonsignificant. Current evidence is limited by unstandardized training dosage/duration, limited linguistic generalizability across non-English languages, and insufficient assessment of patient-reported real-life listening outcomes.
Conclusions:
ACT produces consistent short-term improvements in speech-in-noise recognition and memory-related functions. Integrated auditory-cognitive training. Future research should focus on standardized training protocols, real-life hearing assessments, multilingual tool adaptation, and long-term outcome monitoring to advance the clinical application and generalizability of ACT.
