Characterisation of upper airway obstructions using wide-band snoring sounds
ConclusionThe snoring sound based frequency spectrum index has the potential to characterise full and partial closures of the upper airway. Snoring sounds are spread over a wide spectrum and critical information on the full closure of the upper airway is predominantly carried in frequencies beyond human hearing capacity.
