Acoustic and Spectral Properties of Sound in Sleep Apnea

January 15, 2024 Neuroscience Soner Türüdü

Abstract

This research investigates the acoustic and spectral properties of sound processing in patients diagnosed with moderate to severe obstructive sleep apnea syndrome. Using advanced signal processing techniques and behavioral testing protocols, we examined how sleep-related breathing disorders affect auditory perception and sound processing mechanisms in the brain.

Introduction

Obstructive sleep apnea syndrome (OSAS) is a prevalent sleep disorder characterized by repeated episodes of complete or partial upper airway obstruction during sleep. While the primary symptoms focus on respiratory disturbances, emerging research suggests that OSAS may have broader neurological implications, including effects on auditory processing.

Previous studies have indicated potential correlations between sleep disorders and auditory function, but comprehensive analysis of acoustic and spectral sound properties in OSAS patients remained limited. This research aims to fill that gap through systematic investigation using both objective measurements and behavioral testing protocols.

Methodology

  • Participants: 45 patients with moderate to severe OSAS and 30 healthy controls
  • Signal Processing: MATLAB-based acoustic analysis using custom-developed algorithms
  • Behavioral Testing: Online experiments using jsPsych framework for auditory perception assessment
  • Statistical Analysis: Comprehensive data analysis using R programming language

Key Findings

Spectral Analysis

Significant differences in frequency processing between OSAS patients and controls, particularly in the 2-8 kHz range.

Temporal Processing

Reduced temporal resolution in sound processing, affecting speech perception in noisy environments.

Conclusion

This study provides compelling evidence for altered auditory processing in patients with obstructive sleep apnea syndrome. The findings suggest that OSAS may have broader neurological implications beyond respiratory symptoms, potentially affecting auditory perception and sound processing capabilities.

These results have important clinical implications and may inform future therapeutic approaches for OSAS patients experiencing auditory processing difficulties.
