Impact of Acute Versus Chronic Unilateral Hearing Loss on Head Movement in a Novel Binaural Task.
Article in The Laryngoscope, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesIndividuals with single-sided deafness (SSD) may develop adaptive listening strategies with head movement patterns to optimize monaural localization and speech-in-noise understanding. Granular understanding of adaptive behaviors may better inform rehabilitation for SSD. We aimed to characterize head movements during a combined localization and speech-in-noise task to understand how adaptive behaviors emerge.
methodsProspective study from a tertiary referral center with 16 subjects with normal hearing (NH) and 15 SSD subjects. Sentences were played in a semi-anechoic chamber from one of 24 speakers in a 360° azimuthal configuration with a variable signal-to-noise ratio. Head position was captured via an electromagnetic tracking system. NH subjects completed the task twice, once with a deeply-seated earplug and supra-aural earmuff to simulate acute unilateral hearing loss and once unoccluded. Outcome measures included localization accuracy (mean absolute error, slope across targets), head movement (onset delay, total response time, total head displacement), and speech-in-noise performance.
resultsUnoccluded NH subjects displayed accurate localization, minimal movement delay, rapid response time, low total head displacement, and high speech-in-noise percent correct compared to the occluded condition and SSD subjects. Localization accuracy and SIN performance were comparable between NH occluded and SSD; however, the groups had distinct head movement patterns.
conclusionsAcute unilateral hearing loss leads to sharp declines in localization accuracy and speech-in-noise performance. In SSD, difficult listening conditions may prompt the development of distinct head movement patterns over time. This work provides key initial insight into adaptive listening strategies that individuals with SSD may acquire and utilize in complex listening environments. LEVEL OF EVIDENCE: 3:
