Effect of Age and Speech Perception at Different Signal-to-Noise Ratios Among Children With Normal Hearing.
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. 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
BACKGROUND AND
objectivesChildren constantly gain auditory experiences that promote speech and language development. Therefore, evaluating the auditory capacities of children in noisy environments is imperative. In this study, we sought to evaluate the speech perception abilities of children with normal hearing in noisy environments. SUBJECTS AND
methodsA cross-sectional study design was employed, enrolling 162 Tamil-speaking children aged 3-6 years with normal hearing. These children were further categorized into three groups based on age range: group 1 (3;0-3;11 years), group 2 (4;0-4;11 years), and group 3 (5;0-5;11 years). The two-talker babble was recorded and presented under four conditions: silence, 0 dB signal-to-noise ratio (SNR), +10 dB SNR, and +20 dB SNR. Scoring was carried out and recorded appropriately.
resultsA significant difference (p<0.05) in performance was observed at 0 dB SNR and +10 dB SNR compared to that in the other two presentation conditions. Among all the age groups assessed, performance was poorer in those exposed to 0 dB SNR, whereas near-perfect scores were recorded among those exposed to 20 dB SNR.
conclusionsOur findings provide a basis for comparing the performance of children utilizing hearing devices in noisy environments. This normative data can also serve as a benchmark for evaluating the performance of children with hearing loss fitted with hearing devices.
