In the last two decades, there has been a considerable uptick of soundscape studies. With various agents advocating for more diverse and inclusive approaches to urban acoustic environments, the need to establish practical guidelines arises. To support this process, the Catalogue of Soundscape Interventions (CSI) project was initiated, which provides an online repository for data collection and communication of soundscape interventions, globally. Within this framework, a soundscape intervention is understood as a location-specific design, aimed at preserving or enhancing the existing acoustic environment. The criteria that have to be met to classify a project as a soundscape intervention, as well as ways to implement and assess design improvements are currently being debated. To help identify and derive recurring strategies and aims in current practices, this paper categorizes 37 projects collected via the CSI platform by means of a five-type intervention typology, adopted from noise intervention literature. The collected projects are further classified in subtypes, based on the approaches used to influence the acoustic environment, as well as their level and stage of public involvement. Finally, the need to adapt the resulting typology to accommodate all current practices is discussed.
