Does a new, full-night automatic system for the detection of snoring provide information on the acoustic characteristics of snores that differ in relation to the apnea-hypopnea index (AHI)?

Background: The probability of obstructive sleep apnea syndrome (OSAS) is 3.2 times higher in snorers than in non-snorers. Although several studies have shown differences in acoustic snoring characteristics between patients with OSAS and simple snorers, usually only a few manually isolated snores have been analyzed, with an emphasis on postapneic snores in OSAS patients.
Although automatic snore detection systems may offer more objective measurement over a longer period of sleep, they have not been applied to full-night analysis, mainly because of problems of recording noise from ambient sounds.
