The gold standard for diagnosing sleep apnoea–hypopnoea syndrome (SAHS) is
polysomnography (PSG), an expensive, labour-intensive and time-consuming procedure …

A novel method for screening obstructive sleep apnea syndrome (OSAs) based on nocturnal
acoustic signal is proposed. Full-night audio signals from sixty subjects were segmented into …

Obstructive sleep apnea syndrome (OSA) is of increasing importance because of its high
prevalence and danger of morbidity to untreated patients. Diagnostic procedures need …

Correlation between snoring and obstructive sleep apnea (OSA) has been studied over the
past years using techniques such as sound intensity computation, power spectrum …

Introduction Obstructive sleep apnea (OSA) is common, and diagnosis requires expensive
and laborious testing to assess the apnea hypopnea index (AHI). We performed an analysis …
