Description
Translating soundscape research into clinical practice requires empirical evidence of efficacy. It also needs structured, operationalizable guidance for implementation. This presentation addresses that translational gap through a case study, focusing on soundscape augmentation in a specialized dementia unit serving individuals aged 65 and older with moderate to severe dementia. In this setting, complex acoustic dynamics frequently exacerbate agitation and impede care delivery.Drawing on findings from a pilot randomized controlled trial that demonstrated a reduction in resistance-to-care behaviours through targeted soundscape augmentation, the presentation outlines an implementation protocol. The protocol begins with a soundscape investigation following ISO/TS 12913-2 to characterize the ambient acoustic environment. Sound selection prioritizes higher sharpness values and natural vocalizations, delivering gentle alertness cues during morning care and energetic masking during evening routines, at levels slightly above ambient background (40–60 dBA). The system operates autonomously within existing care workflows, supports immediate muting, and accommodates age-related hearing impairment. A real-time feedback mechanism enables ongoing personalization without requiring additional workforce, leveraging existing clinical observation competencies.This implementation model is presented as a replicable protocol with direct relevance to the ongoing development of ISO/CD TS 12913 series, addressing a population whose perceptual characteristics are largely absent from existing soundscape design standards.
