The University of Antwerp is spearheading the most extensive citizen survey ever conducted on sound levels in Flanders. Commencing this Tuesday, The Great Sound Survey invites individuals

to participate, aiming to investigate how sound impacts daily life in the region.

The collaborative project, titled "De Oorzaak," involves the University of Antwerp, the University Hospital Antwerp, and the newspaper De Morgen. It commenced in September and seeks to meticulously chart the sounds people encounter daily and their effects on health.

High noise levels are among the primary environmental factors contributing to health issues, as stated by the World Health Organization. Persistent exposure to disruptive environmental noise can lead to conditions like heart disease, diabetes, and mental disorders.

During the initial phase of the project, participants create a sound report based on specific criteria. Researcher Jonas Lembrechts notes, "Over six thousand participants mapped their sound environment during a walk." Results revealed that 22% found the surrounding sound pleasant, while 56% described it as unpleasant. Complete silence was rarely experienced anywhere.

Although the collected data is subjective, it will be amalgamated with scientific data acquired throughout the project's duration.

Residents in Antwerp, Ghent, and Leuven have the option to volunteer for the installation of a smart sound sensor at their bedroom window. Around 2400 individuals will receive these sensors for a two-month period.

The Great Sound Survey marks the official initiation of the research. All Flemish individuals aged 18 and above can participate by completing the online questionnaire, which inquires about potential noise disturbances and their sources.
