Effect of Implementing a Noise Reduction Bundle on Critical Care Nurses' Knowledge and Practice in Adult <scp>ICU</scp>

Noise in intensive care units (ICUs) is a critical environmental stressor that affects both patients and healthcare professionals. Excessive noise disrupts patient sleep, delays recovery, increases stress and contributes to staff fatigue and communication errors. Implementing a structured noise reduction bundle provides a practical and evidence-based approach to minimise unnecessary sound exposure, enhance patient comfort and promote safer, more focused clinical environments. Strengthening ICU nurses' knowledge and adherence to noise reduction practices fosters a culture of awareness and accountability that supports high-quality, patient-centred care.
