Arm Intervention/treatment
Experimental: Earplugs
Subjects randomized to this arm of the study will wear earplugs during their baseline sleep study (polysomnogram).
 Other: Soft earplugs are worn during sleep study
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.
Other Name: Howard Leight (Sperian) Max-1/3303361 uncorded earplugs, NRR33, SNR 37dB
No Intervention: Comparison group
Subjects randomized to the comparison arm will not wear earplugs during their baseline sleep study.
