SlEEp diSruption & dEprivationstudies show that noise often leads to fragmented sleep patterns; preventing patients from progressing into deeper and more restorative sleep stages

intEnSivE carE unitSin a survey of neurosurgery iCu patients, among those who reported sleep disturbance, 58% considered environmental noise a frequent disturbing factor.
another study of iCus suggested that about 20% of arousals and awakenings were related to noise.
another study showed that participants assigned to iCu noise conditions took longer to fall asleep, slept less, and experienced more awakenings and poorer sleep quality.
