Study Design

Allocation randomized
Intervention model parallel assignment
Masking single blind (outcomes assessor)
Subjects randomized to this arm of the study will wear earplugs during their baseline sleep study (polysomnogram).
soft earplugs are worn during sleep study Howard Leight (Sperian) Max-1/3303361 uncorded earplugs, NRR33, SNR 37dB
Subjects are asked to wear earplugs when possible for 3-5 nights prior to their baseline sleep study. On the night of their sleep study they are randomized to either "wears earplugs" or "no earplugs" groups.
(No Intervention)
Subjects randomized to the comparison arm will not wear earplugs during their baseline sleep study.

Primary Outcomes

Sleep measures (rates of apneas and hypopneas, oxygen desaturation, arousals, sleep stages, respiratory cycle-related EEG changes [RCREC])
time frame: up to 2 years after the sleep study

Secondary Outcomes

Subjective sleepiness measures (Stanford Sleepiness Scale)
time frame: on awakening after the sleep study

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Adults, ages 18 or older - Scheduled at the University of Michigan Sleep Disorders Center for a diagnostic polysomnogram to evaluate for sleep-disordered breathing Exclusion Criteria: - Medical, psychiatric or other conditions that would interfere with interpretation of the results of the sleep studies or the subject's ability to complete the Stanford Sleepiness Scale
