Abstract Background and Objectives Sound is an important environmental factor that influences the expression of behavioral psychological symptoms dementia. Recent research on effect soundscape has shown promising results in improving impact people with However, no controlled studies have aimed to quantify effects intervention resident outcomes. The aim this study was assess feasibility a dementia symptoms. Research Design Methods Pilot single-blind repeated-measures randomized trial augmented intervention. Participants were hospital-based specialized unit. delivered their room morning evening or treatment as usual, 2 baseline weeks 4 weekly post-randomization assessments primary secondary Results feasible terms recruitment, retention, delivery There improvements neuropsychiatric inventory total scores over time both groups (−5.89, 95%CI −8.45 −3.28, p < .001), but differences between groups. significant group, time, group × for Pittsburgh Agitation Scale (PAS) score. For PAS-resisting care subscale, there difference, greater reduction period (−0.81, 95% CI −1.59 −0.03, = .042). Discussion Implications In pilot study, augmentation effective nonpharmacological approach reducing resistance dementia, although it did not improve more globally.
