Objectively measured hospital noise can range as high as 67 dB in the intensive care unit to 42 dB in surgical wards, far from the World Health Organization (WHO) international recommendations of 30 dB for patient rooms.1 Although almost half of Medicare patients report that their hospital rooms were not quiet at night, data to objectively characterize noise levels and sleep in hospitalized adults in medical wards are limited.2 One study that objectively measured sleep and noise among hospitalized adults older than 70 years found no association.3 This study aimed to objectively measure noise and sleep duration in adult medical ward patients.
