A Cross-Sectional Study of the Time of Onset of Hearing Loss in Bus Drivers Following Exposure to Occupational Noise.
Article in Journal of audiology & otology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 AND
objectivesOccupational noise exposure is a significant risk factor for hearing loss, affecting approximately 5% of the global population. Although noise-induced hearing loss is commonly associated with reduced sensitivity to pure tones, there is limited information regarding when this hearing loss begins after noise exposure. This study aimed to investigate the time of onset of hearing loss in bus drivers exposed to noise for varying durations. SUBJECTS AND
methodsThe study involved 102 bus drivers aged 25-40 years who had been exposed to noise for periods ranging from 6 months to over 10 years. A control group comprising 102 age-matched individuals without noise exposure was also included. Pure-tone audiometry was performed to assess hearing loss, and time of onset of hearing loss relative to noise exposure duration was evaluated.
resultsBus drivers experienced only "slight" hearing loss, even after 10 years of noise exposure. By contrast, reduced sensitivity to pure tones was observed after 25 to 48 months of exposure.
conclusionsThis study confirms that prolonged noise exposure leads to "slight" hearing loss, which can appear as early as 25-48 months after exposure to noise. Among individuals under 40 years of age, significant hearing loss appeared to occur only after 10 or more years of exposure. These findings suggest that the impact of noise on hearing acuity may have been overestimated in previous studies.
