Noise pollution in the intensive care unit (ICU) can distract healthcare professionals during high-risk tasks such as medication preparation. This increases the risk of errors and may compromise patient safety. This dissertation demonstrates that noise levels in the ICU are well above the World Health Organization (WHO) recommended limits. In particular, peak noise events—such as unnecessary alarms and conversations between healthcare professionals—disrupt concentration and are major sources of annoyance and distraction. A combination of behavioral, technical, and environmental (architectural) interventions can reduce unnecessary alarms, decrease perceived noise disturbance, and lessen nurses' distraction. By reducing noise-related disturbance and distraction, these interventions can contribute to better working conditions and a safer ICU environment. Achieving sustainable improvement requires more than technical solutions alone. An integrated approach—featuring a supportive work environment, strong teamwork, a positive team culture, engaged leadership, and a commitment to continuous improvement—is essential to creating an ICU that is both quieter and safer.
