Snoring and obstructive sleep apnea severity

Most people with obstructive sleep apnea (OSA) snore regularly. But not all snorers have OSA. And screening those individuals is tough. In the Sleep Journal, researchers studied the acoustical properties of snorers, to see if they could predict sleep apnea severity. They used a microphone that was placed near the patient and used sophisticated software to analyze the signals. They then compared the snoring qualities to actual sleep study results and found that they could predict OSA severity based on those snoring acoustics. The authors suggest that this method could be used as a screening tool to help distinguish those that snore with from those without OSA.
