Scene-Specific Self-Tuning of Hearing Aids Enhances Perceived Speech Quality.
Article in American journal of audiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeIndividual older adults with hearing loss often have unique communication needs that vary across different listening conditions. The current study examined whether user-directed fine-tuning of hearing aid programs specifically for different sound scenes would improve perceived speech quality.
methodThirty older adult participants were recruited based on self-reported hearing challenges or pure-tone audiometry indicating a hearing loss. Participants self-tuned the hearing aid frequency-gain characteristics while listening to continuous speech embedded in background noise, presented as simulated real-world sound scenes. The self-tuning procedure was conducted in two sound scenes, "Noisy Indoor" and "Noisy Outdoor," with an average speech level at 60 dB(A) and signal-to-noise ratios of +5 dB and +10 dB, respectively. Speech quality ratings were collected for each scene using an interface inspired by the Multiple Stimuli with Hidden Reference and Anchor method. In each sound scene, participants rated four programs: two self-tuned, one standard prescription based, and one poor-quality anchor. The order of presentation was randomized and blinded.
resultsResults showed that participants rated their self-tuned programs tailored to specific scenes significantly higher compared to both the prescription-based program and their self-tuned program for the other scene.
conclusionUser-driven self-tuning procedures can be useful to capture scene-specific preferences for hearing aid settings and improve the perceived speech quality. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.30359560.
