“…Residents in care facilities might be stimulated even more through technologies and "active" tools that are more person-centered. An example is the use of a parametric speaker, a high-directional loudspeaker transmitting sound in a narrow acoustic space, to create personal space in a common room (Nishiura et al, 2018). Actively designing soundscapes, for instance, using the residents' sensitivity and preference, might be another valuable approach.…”

Objectives: Nursing home residents with dementia are sensitive to detrimental auditory environments. This paper presents the first literature review of empirical research investigating (1) the (perceived) intensity and sources of sounds in nursing homes, and (2) the influence of sounds on health of residents with dementia and staff. Design: A systematic review was conducted in PubMed, Web of Science and Scopus. Study quality was assessed with the Mixed Methods Appraisal Tool. We used a narrative approach to present the results. Results: We included 35 studies. Nine studies investigated sound intensity and reported high noise intensity with an average of 55–68 dB(A) (during daytime). In four studies about sound sources, human voices and electronic devices were the most dominant sources. Five cross-sectional studies focused on music interventions and reported positives effects on agitated behaviors. Four randomized controlled trials tested noise reduction as part of an intervention. In two studies, high-intensity sounds were associated with decreased nighttime sleep and increased agitation. The third study found an association between music and less agitation compared to other stimuli. The fourth study did not find an effect of noise on agitation. Two studies reported that a noisy environment had negative effects on staff. Conclusions: The need for appropriate auditory environments that are responsive to residents’ cognitive abilities and functioning is not yet recognized widely. Future research needs to place greater emphasis on intervention-based and longitudinal study design.

“…Lack of external stimuli is a prominent cause of negative emotions in older people with dementia. Studies have found that sensory stimulation through acoustic intervention can reduce the agitation behavior of older people with dementia (Riley-Doucet and Dunn, 2013 ; Nishiura et al, 2018 ; Syed et al, 2020 ). Therefore, how to create a healthy acoustic environment for the older with dementia has become an urgent problem for countries worldwide to be solved.…”

This research uses facial expression recognition software (FaceReader) to explore the influence of different sound interventions on the emotions of older people with dementia. The field experiment was carried out in the public activity space of an older adult care facility. Three intervention sound sources were used, namely, music, stream, and birdsong. Data collected through the Self-Assessment Manikin Scale (SAM) were compared with facial expression recognition (FER) data. FaceReader identified differences in the emotional responses of older people with dementia to different sound interventions and revealed changes in facial expressions over time. The facial expression of the participants had significantly higher valence for all three sound interventions than in the intervention without sound (p < 0.01). The indices of sadness, fear, and disgust differed significantly between the different sound interventions. For example, before the start of the birdsong intervention, the disgust index initially increased by 0.06 from 0 s to about 20 s, followed by a linear downward trend, with an average reduction of 0.03 per 20 s. In addition, valence and arousal were significantly lower when the sound intervention began before, rather than concurrently with, the start of the activity (p < 0.01). Moreover, in the birdsong and stream interventions, there were significant differences between intervention days (p < 0.05 or p < 0.01). Furthermore, facial expression valence significantly differed by age and gender. Finally, a comparison of the SAM and FER results showed that, in the music intervention, the valence in the first 80 s helps to predict dominance (r = 0.600) and acoustic comfort (r = 0.545); in the stream sound intervention, the first 40 s helps to predict pleasure (r = 0.770) and acoustic comfort (r = 0.766); for the birdsong intervention, the first 20 s helps to predict dominance (r = 0.824) and arousal (r = 0.891).

“…For instance, interventions were observed to have varying effects on agitation levels among residents, with some showing reductions [ 19 , 30 , 40 , 46 , 50 ], meanwhile a study reported no significant changes [ 22 ]. Similarly, few interventions were found to impact overall behavioral and psychological symptoms of dementia (BPSD) demonstrating a decrease in these symptoms [ 19 , 22 , 38 , 40 , 46 ], while others showed inconclusive results on this outcome [ 27 ]. Other studies have shown the potential for some technology to enhance communication among residents and their caregivers [ 21 , 26 , 31 , 32 , 41 , 42 , 48 ].…”

Background To map the current state of knowledge about the use of technology with seniors with neurocognitive disorders in long-term care to foster interactions, wellness, and stimulation. Methods Cumulative Index to Nursing and Allied Health Literature (CINAHL Plus); MEDLINE; PsycINFO; Embase and Web of Science were searched in eligible literature, with no limit of time, to describe the current use of technology by seniors with neurocognitive disorders in long-term care. All types of literature were considered except for theses, editorial, social media. This scoping review was built around the recommendations of Peters et al. (2020 version). Three researchers collaborated on the selection of articles and independently reviewed the papers, based on the eligibility criteria and review questions. Results The search yielded 3,605 studies, of which 39 were included. Most technology type reported was robotics. Included studies reports different positive effects on the use of such technology such as increase of engagement and positive. Conclusion The study highlights different types and potential benefits of technology for long-term care residents with neurocognitive disorders, emphasizing the crucial need for additional research to refine interventions and their use.
