Sleep Apnea01:21

Sleep Apnea

208
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Area of Science:

  • Sleep Science
  • Biomedical Engineering
  • Acoustic Analysis

Background:

  • Snoring significantly impacts bed partners and is linked to chronic diseases.
  • Accurate estimation of whole-night snoring duration remains a challenge.
  • Acoustic analysis offers potential for objective snoring assessment.

Purpose of the Study:

  • To develop and validate a dependable algorithm for visualizing and quantifying snoring durations.
  • To assess the reproducibility of the developed algorithm for snoring analysis.
  • To compare the algorithm's performance against existing methods.

Main Methods:

  • Acoustic recordings were captured using a digital recorder and a smartphone app.
  • Spectrograms were generated from audio files to visualize snoring segments.
  • A novel algorithm was developed to identify and quantify snoring intervals from amplitude and frequency data.

Main Results:

  • The algorithm successfully visualized snoring durations by identifying characteristic amplitude spikes and frequency bands.
  • Analysis of 37 recordings from 6 individuals demonstrated high reproducibility.
  • Correlative coefficients indicated strong agreement between manual analysis (Examiners A & B) and the algorithm.

Conclusions:

  • A dependable and reproducible algorithm for visualizing snoring duration has been developed.
  • This acoustic analysis method provides a reliable tool for snoring quantification.
  • The algorithm aids in understanding snoring patterns and their clinical implications.
