This two-year project is a collaboration between the city of Leuven, the city of Ghent, KU Leuven and Ghent University. In this project, night noise will be measured and recognized at different locations in the two largest Belgian student cities (Ghent and Leuven) in order to get a broad view of nighttime noise pollution. A noise recognition model will be used for this purpose. In addition to the objective data from the measurements, subjective data on noise pollution will also be examined. In Ghent, the subjective data will be collected and analyzed by Ghent University through participation, surveys, and reports from citizens to various entities, including the Police, and city services responsible for supervision, prevention and security. Both cities will try to tackle night noise preventively through nudging techniques. In Ghent, Ghent University will focus on the development of new nudges and examine their effectiveness by providing different measurement moments and checking extinction or displacement effects. Moreover, the Ghent University research team will focus on developing 'deliberative' nudges, starting from co-creation with stakeholders (partygoers, residents, and organizers) to develop an appropriate nudging technique. During this project and afterwards, Ghent University will collaborate with KU Leuven to compare the project results in both cities, creating extra added value and insights in nighttime noise pollution and nudging as a prevention technique.
