Abstract: The invention provides a method of determining a breathing resistance index of a sleeping subject from a set of respiratory sounds. The method includes the steps of selecting a first set of respiratory events of the set of respiratory sounds and manually determining a classification content of the first set of respiratory events. The method further includes extrapolating the classification content of the first set of respiratory events to an at least second set of respiratory events and determining a breathing resistance index based upon the classification content of the at least second set of respiratory events.

Abstract: The invention provides a method of detecting, analyzing sleep disorders. The method includes the step of monitoring sound produced by a sleeping subject through a sensor proximate the sleeping subject and continuously recording the monitored sound. The method further includes identifying snoring within the recorded sound and analyzing the identified snoring to localize upper airway structural sources of snoring.
Abstract: An adaptive snoring signal suppression system globally cancels snoring signals by determining a canceling signal based on a received snoring signal. The system creates a doublet between a plane of a speaker and the source of the snoring signal such that at the plane of the speaker, the canceling signal is 180 degrees out of phase with the snoring signal as measured at the source. The system uses digital signal processing to adaptively estimate a snoring sound canceling signal based on past snoring signals.
