This soundscape supports the environment and makes the environment feel safer and more 'clear' for residents with dementia. We try to add a recognizable (safe, orientating) sound through the soundscape system. In the soundscapes, we use only recognizable sounds, sounds that give persons with dementia a feeling of 'safety' or sounds that focus on the orientation (in time, place). The aim of this study is to build upon the previous research and evaluate the effect of a personalized soundscape on the well-being and behaviour of persons with dementia. There were no harms documented in the study, and if residents reacted not well to specific sound, the sound was removed from the soundscape. They did not directly assess the benefits to residents in that study. In a previous study in people with dementia by the Belgian investigators in this study (Devos et al., 2019), they observed positive staff outcome measures, reflecting the value of the soundscape in improving their ability to provide care to people with dementia. The health outcomes vary, but include cardiovascular disease, sleep disturbance, and annoyance. There is substantial research on the effect of noise (unwanted sound) on people's health and well-being.

Bringing sound with this purpose, as targeted to the current activity can improve the behaviour.

Sound plays a role in generating a feeling of safety, in influencing the mood, and triggering a specific action. Research has shown the positive effect of natural and non-natural soundscape on people with severe or profound intellectual disabilities (Andringa & van den Bosch, 2013). Other: Acusticare Other: Treatment as usual Condition or diseaseĭementia Behavioural and Psychiatric Symptoms 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. Behaviour associated with the appraisal of the sound environment may change with the emergence of dementia. However, also at an earlier perceptual stage, attention focusing and gating may be affected, reducing their ability to analyze a complex auditory scene. The most obvious difference is that the meanings they may give to the sounds they notice due to changing mental associations. People with dementia, however, perceive and understand the sonic environment differently. 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.
