BACKGROUND Annoying snore is the principle symptom and problem in obstructive sleep apnea syndrome (OSAS). However, investigation has been hampered by the complex snoring sound analyses. OBJECTIVE This study was aimed to investigate the energy types of the full-night snoring sounds in patients with OSAS. PATIENTS AND METHOD Twenty male OSAS patients underwent snoring sound recording through...

OBJECTIVE Although awareness of sleep disorders is increasing, limited information is available on whole night detection of snoring. Our study aimed to develop and validate a robust, high performance, and sensitive whole-night snore detector based on non-contact technology. DESIGN Sounds during polysomnography (PSG) were recorded using a directional condenser microphone placed 1 m above the b...

Enlarged Adenoids is a disease which results in the blockage of air passage of infants. These babies who are infected with adenoids will produce high snoring sounds while they sleep. For children suffering from adenoid, it‟s a heart breaking scene for a parent to see their small innocent baby could sleep only in a sitting position. The sound of snore produced by such babies is too loud, that it...

Snoring is a common symptom of serious chronic disease known as obstructive sleep apnea (OSA). Knowledge about the location of obstruction site (VVelum, OOropharyngeal lateral walls, T-Tongue, E-Epiglottis) in the upper airways is necessary for proper surgical treatment. In this paper we propose a dual source-filter model similar to the source-filter model of speech to approximate the generatio...

STUDY OBJECTIVES A link between gastroesophageal reflux (GER) and obstructive sleep apnea (OSA) has been suggested; however, the prevalence and frequency of symptomatic GER and the influence of OSA severity on GER are not known. DESIGN AND PATIENTS Two hundred seventy-one subjects referred for overnight sleep studies were investigated for subjects with a breathing sleep disorder, occurrence o...

1299 Analysis of Nocturnal Snoring Signal—Ben-Israel et al INTRODUCTION Obstructive sleep apnea (OSA) is a chronic disorder affecting 2% to 7% of adults and can lead to considerable morbidity.1 Partial or complete collapse of the upper airway during sleep has different effects on the human body, ranging from noisy breathing (simple snoring)2 to cardiovascular morbidity.3 Snoring is the most com...
