A Voice Ergonomic Study in Icelandic Preschools: What Causes the Activity Noise and How to Attenuate It.

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
introductionPreschool sound environments are predominantly shaped by activity noise generated by voices, object impacts, furniture movement, and daily transitions. Although Icelandic preschools typically comply with reverberation standards, staff frequently report excessive noise, high listening effort, and vocal strain.
methodsThis mixed-method pre-post study examined the sources and reducibility of activity noise in three Icelandic preschools using a voice-ergonomic framework. Data included objective noise measurements at child ear height, structured observations, and teacher questionnaires. The intervention combined voice-ergonomic and noise-awareness education for staff and children with targeted organisational, behavioural, and material adjustments.
resultsBaseline mapping identified children's voices and object impacts as the dominant noise sources. Following the intervention, measured noise decreased significantly, with mean L
conclusionThe findings indicate that activity noise represents the primary acoustic challenge in preschool environments and highlight children's particularly high local noise exposure. The results support the need for more child-centred acoustic standards that extend beyond reverberation time alone and place greater emphasis on favourable signal-to-noise conditions, listening effort, speech communication, and vocal health in preschool environments.
