Randomized clinical trial in soundscape research

The mechanism that connects the sonic environment to how it is perceived and understood by persons are becoming more evident, and there are standardized methodologies for assessing the soundscape. The importance of the sonic environment on the health and wellbeing of people is well known. Therefore, using the Soundscape approach to design an atmosphere that improves people's quality of life is essential. This approach is more challenging for people with cognitive difficulties; in this study, people with dementia. Our approach is to use a randomized clinical trial, a well-known scientific method in healthcare studies, to validate the soundscape effect on persons with dementia. This study uses a personalized algorithm; based on questionnaires and evaluations to play sounds at prescheduled moments through a day in patients' rooms in a research hospital specializing in dementia care for six weeks for each study group. This study's objective is to measure the effectiveness of the customized soundscape on agitation, distress, night sleep, stress, and quality of life through carefully developed data collection and analysis. The results and data will have a significant impact on designing soundscape for people with dementia and introducing the clinical method in data collection, focusing on measurement through clinical research.
