A decibel (dB) level no higher than 45. has been recommended by Garre-Olme, López-Pousa, Turon-Estrada, et al. The low-level sounds in social areas has proven to be beneficial and thus should be implemented at certain times of the day, such as activity and meal times (2012). A staff controlled sound masking device can be helpful in allowing staff to adjust the noise levels accordingly.
Design and dementia has recommended that Sound Transmission Class (STC) ratings of dividing walls be 45 STC between rooms and the corridor; 65 STC is recommended between rooms and mechanical spaces (2011).
A soundproof HVAC system as well as sound absorbing materials, can also be helpful in reducing noise throughout the halls (Design and dementia, 2011).
The integration of familiar music or sounds from a patient’s youth can also help with those who suffer from dementia. These sounds can help lower agitation while also prompting memory and providing a sense of time (for example, the sound of a clock chiming every hour) (Hayne & Fleming, 2014).
