In recent years, several studies have shown the relationship between snoring and obstructive sleep apnea syndrome (OSAS). Instead of time domain analysis of snoring signal, the spectral features and shapes of snores have been found different in simple snorers and OSAS patients. In this study, we propose a method to differentiate simple snorers and OSAS patients based on spectral envelope estimation of snoring signals. Formant frequencies and bandwidths are computed for both groups and the variation and consistency of the formant distributions are determined. A total of 1400 snoring episodes from 7 simple snorer and 7 OSAS patients were analyzed. Significant differences are found in the variation of formant frequencies of both groups. The results are interpreted from a patophysiological view.

Spectral envelope analysis of snoring signals Çavuşoǧlu, Mustafa; Kamaslǎ, Mustafa; Çiloğlu, Tolga; Serinağaoğlu Doğrusöz, Yeşim; Eroǧul, Osman (null; 2008-12-01) In recent years, several studies have shown the relationship between snoring and obstructive sleep apnea syndrome (OSAS). Besides time domain analysis of snoring signal, the spectral features and shapes of snores can be used to discriminate simple snorers and OSAS patients. In this study, we propose a method to classify simple snorers and OSAS patients based on spectral envelope estimation of snoring signals. The formant frequencies and corresponding bandwidths are computed for both group, and the variation...
Analysing snoring sounds for obstructive sleep apnea (OSA) patients Obstrükti̇f uyku apnesi̇ (osa) hastalari i̇çi̇n horlama sesleri̇ni̇n anali̇zi̇ Çavuşoǧlu, Mustafa; Serinağaoğlu Doğrusöz, Yeşim; Eroǧul, Osman (2006-01-01) Several studies have done in order to determine the relationship between snoring and obstructive sleep apnea syndrome (OSAS). One of the common problem that is faced during the medical treatment of the apnea is the undetermination of the efficiency of the applied treatment in terms of objective criteria. It is needed to automatically detect each snoring episode in order to estimate the spectral features and determine the snoring sound intensity. In this study, an automatic detection system of acoustic snori...
Detection of Post Apnea Sounds and Apnea Periods from Sleep Sounds Karci, Ersin; Serinağaoğlu Doğrusöz, Yeşim; Çiloğlu, Tolga (2011-09-03) Obstructive Sleep Apnea Syndrome (OSAS) is defined as a sleep related breathing disorder that causes the body to stop breathing for about 10 seconds and mostly ends with a loud sound due to the opening of the airway. OSAS is traditionally diagnosed using polysomnography, which requires a whole night stay at the sleep laboratory of a hospital, with multiple electrodes attached to the patient's body. Snoring is a symptom which may indicate the presence of OSAS; thus investigation of snoring sounds, which can ...

Serum copper and zinc status in obstructive sleep apnea patients Akyüz, Ahmet Oğuz; Pelin, Z.; Ozogur, S.; Ercan, O. (2006-09-01) Obstructive Sleep Apnea Syndrome (OSAS) is a chronic disease characterized by oxygen desaturation and awakens follow from repetitive apnea and hipopnea during the night. It is thought that diversity of oxygen levels during night in OSAS cause oxidative stress with the increment of the free radical production. In this study, serum levels of copper (Cu) and zinc (Zn), two of the most important elements of antioxidant defense mechanism, were investigated. Patients to be participated into the study were divided...
