Soundscape Evaluations (12-04-20)

Research conducted by Tarlao, Steffens, and Guastavino confirms the many factors can influence perceptions of sound being experienced besides the actual noises themselves. The team reports that “Previous soundscape research has shown a complex relationship between soundscapes, public space usage and contexts of users’ visits to the space. . . . The present study is a comparative analysis of in situquestionnaires collected over four study sites in Montreal . . . . in both French and English. . . .  The analyses. . .. .

Sound and Cognitive Issues (10-22-20)

Weuve and teammates studied links between noise levels experienced at home and cognitive issues. The researchers report that “Participants of the Chicago Health and Aging Project (≥65 years) underwent triennial [every 3 years] cognitive assessments. For the 5 years preceding each assessment, we estimated 5227 participants’ residential level of noise from the community using a spatial prediction model, and estimated associations of noise level with prevalent mild cognitive impairment (MCI) and AD [Alzheimer’s disease], cognitive performance, and rate of cognitive decline.

Window Views: Implications (10-15-20)

Ko and colleagues evaluated how windows influence space user experiences.  They report that they “assessed the influence of having a window with a view [of nature] on thermal and emotional responses as well as on cognitive performance. . . . The chamber kept the air and window surface temperature at 28 °C, a slightly warm condition. . . . In the space with versus without windows, the thermal sensation was significantly cooler ( . . .  equivalent to 0.74 °C lower), and 12% more participants were thermally comfortable.

Lighting for Sleeping (10-08-20)

Investigators have found that varying lighting in nursing homes during the course of the day, so that light intensity and color mimics lighting conditions outdoors, supports better sleep among residents. Baier, Miller,  McCreedy, Uth, Wetle, Noell-Waggoner, Stringer, and Gifford, used data collected from study participants with an average age of 88 to better understand sleep related issues among nursing home residents: “Nursing home residents tend to fall asleep at all hours of the day, and during the night, their sleep may be interrupted by periods of wakefulness. . .
