The main objective of WP3 is to construct an enriched description of the external exposome by developing detailed data and new, open-source models for the built- and natural- environments, air pollution, and noise.
As input for the work in WP3, the new exposure metrics identified by WP1 are considered. Also, enhancing environmental and population characteristics are constructed by combining data from WP5 with data generated in WP3.
WP3 will not directly make use of the existing cohort and school study data, but will enrich these data with newly developed the exposure data. Also, a study comparing children and young adults is planned, comprising listening experiments among 3-10 years old and young adults (18 - 30 years old).

The main objective of WP3 is to formulate an extensive description of the external exposome. This is done by developing new models that enriches the database on the built- and natural- environments, air pollution, and noise.
So far, WP3 has been identifying and defining various environmental exposure indicators, for the built and natural environment, WP3 has also developed methods to improve the granularity (density of roads represented and traffic composition) of data on traffic flows to feed air quality and noise models.
In these processes, partners from different work packages have been collaborating to establish data compatibility. The scientific literature has extensively been reviewed on the link between noise exposure and health effects in children other than their hearing as an outcome only. A new prediction model for sleep disturbance and noise annoyance are under development.
Some of the external exposome measurements and the timely process of obtaining datasets have been delayed due to COVID-19.
