This article investigates the approaches and attributes of publicly situated sound installations which have achieved the status of permanency, and have attracted ongoing local, and even international, visitors. The article draws on international fieldwork in 2015 that documented several enduring sound installations in the United States, UK and Europe. Through an inductive process including listening exercises, sound recordings, observations and interviews, the analysis identifies three approaches to creating sound installations and ten attributes of operative sound installations. It is argued that by encouraging public listening, the discussed sound installations successfully establish a sensory connection between people and their environments. By extension, it is argued that this emergent sense of place is commensurate with the installations’ capacity to augment a pre-existing ‘spirit of place’. These findings culminate in a sonic placemaking tool for situating sound art installations in urban spaces. It is suggested that urban planners and designers can apply the presented sonic placemaking tool to augment a site’s spirit of place, thereby affecting new experiences in everyday urban life.
