• Individual

Children aged 4 to 6 years enrolled in municipal preschools in western Sweden. The population includes typically developing children without known hearing impairments, participating in regular preschool activities during the data collection period.

• Cross-section ad-hoc follow-up

Children aged 4–6 years were recruited from participating Swedish preschools as part of a field study on noise exposure and hearing function. Preschools were selected to reflect a variety of physical layouts, group sizes, and noise conditions. Within each preschool, all children in the relevant age group were invited to participate. Inclusion was based on parental consent and the child's ability to comply with the measurement procedures. No stratification or randomisation was applied. The sample is thus a convenience sample with ecological validity, reflecting naturalistic variation in preschool settings.

34.7%

Out of 288 invited participants, informed consent was obtained for 100 children (participation rate: 34.7 %). Of these, 75 children were included in the dosimetry analyses, and 56 were included in the analysis of cochlear function (pDPOAE). Inclusion was based on data quality and completeness.

• Numeric

Physical measurements and tests

Hearing data were collected using pressurised distortion product otoacoustic emissions (pDPOAE), conducted in preschool environments using portable equipment. Sound exposure was measured with personal dosimeters (Svantek SV104), worn by children during all or parts of their preschool day. Measurements were performed by trained staff following standardised protocols. Data quality was ensured through tympanometric screening, application of amplitude and signal-to-noise thresholds, and device-specific reliability indicators.

• Göteborg Municipality

The dataset from the 2022–2024 period comprises 15 preschool departments in Gothenburg, Sweden, distributed across four major city districts: Centrum (n = 4), Hisingen (n = 3), Nordost (n = 3), and Sydväst (n = 2). The selection includes preschools located in both central and peripheral parts of the city, such as Örgryte-Härlanda, Norra Hisingen, Angered, Kortedala, Frölunda, and Askim-Hovås. This geographical diversity enables analysis of contextual and acoustic conditions across varied preschool environments.
