Abstract
This paper presents the Soundscape Experience Mapping method for understanding how older adults perceive their indoor acoustic environments. With global ageing, populations are increasingly choosing to age in place. This creates an opportunity to enhance older life through the intentional design of supportive soundscapes for the home. Through a mixed-method approach combining Ecological Momentary Assessment with Cultural Probe methods, we engaged eight older adults (age: 56-76) in Belgium to document their domestic sound-scape experiences. Our analysis identifies four themes of older adults' indoor soundscape experiences: personal agency in shaping acoustic environments, temporal patterns that structure daily routines, sound-memory associations creating place attachment, and social presence through acoustic monitoring that connects individual experiences to broader contexts. Findings demonstrate how sounds function as spatiotemporal anchors, structuring daily routines while fostering place attachment through memory. This design research provides foundational insights for Audio AI applications that support independence for older adults.
