Quantification of NICU acoustic variation across conditions and events. (A) Boxplots of dBA levels from sensors A–D during incubator alarms, ventilator alarms, door ringing, and quietness. (B) Sound level comparison during staff movement across morning, noon, and evening periods versus quietness. (C) Heatmap of average dBA values recorded by each sensor for all monitored events.
