The acoustic environment can prevent and reduce behavioral and psychological symptoms.

Designing soundscapes to improve an individual’s quality of life focuses on placing their perceptions at the center of the process. It becomes more difficult for people with impaired cognitive ability.

At the 180th Acoustical Society of America, effectively held from June 8th to 10th, Ghent University’s Arezo Tarebuzade provided clues about time and place so that a personalized soundscape could help people with dementia. Shows how you can help. The session “Soundscape Design for People with Dementia. Correlation between Psychoacoustic Parameters and Human Perception” will take place on Wednesday, June 9, at 9:35 am in the eastern United States.

A system called AcustiCare is used to create a personalized soundscape with a customized algorithm that plays sounds scheduled at specific times throughout the day. Through feedback, the system can refine the sound played the next day, helping to enhance the time and space of people with dementia.

“Sounds consist of a collection of natural sounds, bird chirping, outdoor sounds, water / rain sounds, kitchen sounds, music, bell sounds, and more,” said Tarebuzade. “From these sounds, we use psychoacoustic parameters and metadata to get similarity information between different sounds. This information is used to suggest new sounds related to the feedback findings. . “

The purpose of Talebzadeh’s research is to discover the correlation between psychoacoustic environment and mood changes, and hopes to elicit a response that elicits a safe sensation. Soundscape improves sleep quality, reduces agitation, anxiety, and distress, and reduces the behavioral and psychological symptoms of dementia, the use of psychotropic drugs, and the stress of caregivers and staff. May improve the quality of life of people.

“One of the environmental factors is the infrastructure of the care facility,” says Tarebuzade. “A variety of changes can be made to support a dementia-friendly environment, which can also help prevent or alleviate the behavioral and psychological symptoms of dementia. Sound is one of the environmental factors.” A personalized soundscape that helps people with dementia with time and place awareness
