Do snoring sounds arouse the snorer?

ABSTRACT:

Study objectives

Respiratory cycle-related electroencephalographic (EEG) changes (RCREC), especially in delta and sigma frequencies, are thought to reflect subtle, breath-to-breath inspiratory microarousals that are exacerbated in association with increased work of breathing in obstructive sleep apnea (OSA). We wondered whether snoring sounds could create these microarousals, and investigated whether earplugs, anticipated to alter snoring perception, might affect RCREC.

Design

Randomized controlled trial.

Setting

An accredited, academic sleep laboratory.

Patients

Adults (n = 400) referred for suspected OSA.

Interventions

Subjects were randomly assigned to use earplugs or not during a night of diagnostic polysomnography.

Results

Two hundred three o
