Challenging behavior (CB) is a group of behaviors, reactions and symptoms due to dementia, which can be challenging for the caregivers. The study aims to research the influence of acoustics on CB in people with dementia (PwD). An ethnographic method was used to study the daily life of PwD in their nursing homes with a specific focus on how people react to everyday environmental sounds. Thirty-five residents were included in the sample based on purposeful, homogeneous group characteristics and sampling. Empirical data were collected using 24/7 participatory observations. The collected data were analyzed using a phenomenological-hermeneutical method: a naïve understanding, a structural analysis and a comprehensive understanding. The result shows that the onset of CB depends on whether the resident feels safe and is triggered by an excess or lack of stimuli. The excess or shortage of stimuli and whether and when it affects a person is personal. It depends on various factors, the person's state and the time of day, the nature of the stimuli, familiarity, or strangeness is also a determining factor for the onset and progression of CB. The results can form an essential basis for developing soundscapes to make the PwD feel safe and reduce CB.
挑战性行为（CB）是一组由于痴呆引起的行为、反应和症状，可能会对护理人员造成挑战。本研究旨在研究声学对痴呆症患者（PwD）的 CB 的影响。采用民族志方法研究了 PwD 在疗养院的日常生活，特别关注人们对日常环境声音的反应。根据有目的、同质的群体特征和抽样，选择了 35 名居民作为样本。使用 24/7 参与式观察收集实证数据。使用现象学-解释学方法分析收集的数据：初始理解、结构分析和全面理解。结果表明，CB 的发作取决于居民是否感到安全，并由刺激过多或过少触发。刺激的过多或过少以及是否以及何时影响一个人是个人的。它取决于各种因素，人的状态和一天中的时间，刺激的性质，熟悉度或陌生度也是 CB 发作和进展的决定因素。研究结果可以为开发声景提供重要基础，使 PwD 感到安全并减少 CB。
