Acoustic Stimulation During Restricted Sleep After Sleep Deprivation

Slow-wave Sleep Enhancement Using Acoustic Stimulation to Facilitate Performance Recovery During Restricted Sleep After Sleep Deprivation

The purpose of this study is to determine if brief sounds or tones presented within a restricted period of recovery sleep after a period of sleep deprivation will enhance restorative properties and improve performance during a subsequent period of wakefulness.

Inclusion Criteria:

• Healthy men and non-pregnant, non-lactating women 18 to 39 years of age (inclusive)

Individuals who fail to achieve a passing score on the initial quiz will be given one opportunity to retest after a review of protocol information. Individuals who fail the comprehension assessment for the second time will be disqualified.
