The Effects of White Noise for Adult Patients' Sleep Quality in Intensive Care Unit.

Poor sleep quality is one of the most common problems among adult patients in the intensive care unit (ICU). The causes of sleep disturbance are complicated. Poor sleep quality can lead to negative consequences for patients' physical and mental health. Non-pharmacological interventions, such as white noise, have been recommended to increase the threshold level of sound during nighttime and achieve masking effects to improve subjective sleep quality. This study is a randomized controlled trial that compared two parallel patient groups.The hypothesis of this study is that white noise can improve sleep quality in adult ICU patients compared with conventional treatment group.
