Excerpt

Alarms from monitors, medical devices and staff activities increase noise levels in the Intensive Care Unit (ICU) and may disrupt sleep patterns [1] contributing to the development of delirium and post-intensive care syndrome [2]. The World Health Organization (WHO) recommend that hospital noise levels should not exceed 35 A-weighted decibels (dBA) during the day and 30 dBA at night [3]. However, daytime noise levels in ICU were found of around 60 dBA [4]. Apple Watch (Series 4 and 5) takes advantage of the internal microphone to regularly sample sound levels in the environment and might play a role in monitoring noise in the ICU. …
