A feasibility study to evaluate the use of white noise to improve sleeping conditions in an ICU setting.
The ICU is full of alarms and critically ill patients, so it is no surprise that sleep is very much fragmented and poor in this setting, as documented in numerous studies. White noise is a simple intervention that has been shown to improve sleep, including in the ICU setting. The aim is to conduct a pilot trial evaluating the feasibility of providing white noise to patients in the ICU at night to help improve sleep. The plan to measure feasibility metrics including patient acceptance, patient tolerance, and intervention fidelity; also to seek feedback from patients, nurses, and providers. Secondly is to evaluate the benefits of providing white noise at night in the ICU on sleep as measured by actigraphy and Richards-Campbell Sleep Questionnaires and total room sound.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| patients exposed to white noise | Experimental | Six patients in the interventional arm will have white noise (through in-room workstations- on-wheels and publicly-available white noise websites) playing overnight at a standardized volume to be determined; pausing will be at nurse, provider, and patient discretion during routine care and conversations with the patients. |
|
| usual care | Placebo Comparator | Six patients exposed to normal ICU activity noise. |

| Sound Levels | Room dBA and dBC-weighted sound levels will be measured in the rooms as well by HD600 sound meters (Extech Instruments) every 10 seconds throughout the night shift; sound meters will be placed on the wall behind and 10" above the head of the bed (set when head of bed is at 30 degrees). | 48 hours |
