Analysis and classification of snoring signals

Snoring is a very common phenomenon with both social and clinical effects. The need for a reliable and effective monitoring and analyzing system, for the snoring signal, stems from the recent awareness of the severity of the problem and from the fact that surgical correction procedures are now available. A preliminary analysis of the snoring signal is presented. Some features, describing the signal are presented. The airway area model is suggested as one of the means to estimate the source and location of the obstruction. The preliminary analysis is demonstrated on a signal recorded from a patient suffering from laryngomalacia. It is shown that the suggested analysis describes the special characteristics of the signal.
