Background and Objectives Snoring is the most common symptom of obstructive sleepapnea (OSA) and is caused by turbulent airflow due to narrowing of the upper airways. In patientswith positional OSA, a change in sleep posture from supine to lateral is known to reducesnoring and sleep apnea. This study was performed to compare changes in snoring sound intensityand formant frequencies according to sleep position. Subjects and Method A total of 19 patients (male: 18; female: 1) diagnosed with positionalOSA by polysomnography (PSG) were enrolled in this study. The snoring sounds recordedduring PSG were analyzed acoustically and compared according to sleep position (i.e., supinevs. lateral). Results Snoring disappeared on changing sleep position in five patients, all of whom hadApnea-Hypopnea Index (AHI) <15. In other patients, the snoring sounds tended to decreasewith posture change, and the degree of decrease was inversely proportional to AHI (p=0.015)and respiratory disturbance index (RDI) (p=0.013). Formant frequencies 1, 3, and 4 (F1, F3,and F4, respectively) decreased when sleeping in the lateral position (p=0.02, 0.03, and 0.01,respectively). Conclusion In patients with positional OSA, a change in sleep posture from supine to lateralduring sleep reduced the intensity and frequency of snoring sound.
