In the last few decades, insights into the impact of the sonic environment on persons have grown to include not only the adverse effects of extensive mechanical noise but also the beneficial effects of a well-designed sonic environment. People with dementia, however, perceive and understand the sonic environment differently. The most obvious difference is that the meanings they may give to the sounds they notice due to changing mental associations. However, also at an earlier perceptual stage, attention focusing and gating may be affected, reducing their ability to analyze a complex auditory scene. Behaviour associated with the appraisal of the sound environment may change with the emergence of dementia. The objective of this study is to determine the effect size of a carefully tuned personalized sonic environment (delivered via AcustiCare) on agitation and distress (NPI and PAS), night sleep and stress (Via wristband) and on quality of life (QUALIDEM) in a population of older adults with dementia and behavioural symptoms.
