Individual Differences in Sensitivity to Everyday Sounds: Developmental, Environmental, and Personality Predictors of Auditory Processing.

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
Background Sensitivity to everyday sounds shows considerable individual variation. This study aimed to identify distinct dimensions of auditory sensitivity and examine how psychosocial and developmental factors, such as early auditory environments and personality traits, shape individual differences in non-clinical adults. In addition, we explored sensitivity to low-salience sounds that are typically perceived as non-intrusive by most people but elicit discomfort in a minority of individuals. Methods A cross-sectional web-based survey was conducted between September and November 2024 with 380 Japanese adults (aged 18-56), using a self-developed questionnaire informed by prior research and pilot testing. Participants rated their affective reactions to 39 everyday sounds. Factor analysis extracted latent auditory sensitivity components. Multiple regression analyses examined the predictive roles of childhood auditory environment and personality traits measured via standardized psychological scales. Results Based on factor analysis of participants' ratings across 39 everyday sounds, two underlying dimensions of auditory sensitivity were identified. These were labeled WLS1 and WLS2, reflecting different patterns of sensitivity: WLS1 represents sensitivity to subtle, non-salient sounds, while WLS2 reflects heightened reactivity to loud or sharp auditory stimuli. WLS1 was significantly predicted by childhood exposure to parental vocal discipline (β = 0.19, 95% confidence interval (CI) (0.07-0.31), p = 0.002), emotional reactivity (β = 0.23, 95% CI (0.09-0.36), p = 0.001), and interpersonal assertiveness (β = 0.24, 95% CI (0.10-0.37), p < 0.001). WLS2 was associated with female gender (β = 0.50, 95% CI (0.27-0.72), p < 0.001), insomnia from worry (β = 0.15, 95% CI (0.04-0.27), p = 0.006), fatigue (β = 0.30, 95% CI (0.17-0.43), p < 0.001), and impulsivity (β = 0.14, 95% CI (0.04-0.24), p = 0.008). A third factor, W1, reflecting sensitivity to ambient mechanical sounds that over 80% of participants rated as non-intrusive, was predicted by orderliness (β = 0.16, 95% CI (0.03-0.25), p = 0.012), emotional sensitivity (β = 0.21, 95% CI (0.08-0.34), p = 0.002), and a preference for uniqueness (β = 0.29, 95% CI (0.15-0.44), p < 0.001). Conclusions Auditory sensitivity is multifactorial and shaped by both developmental auditory experiences and personality dimensions. The results suggest that distinct psychological pathways underlie responsiveness to subtle versus intense auditory stimuli.
