Analyzing infant cries offers a non-invasive method to assess respiratory health in neonatal critical care. This acoustic analysis provides insights into neuro-physiological parameters, aiding in the monitoring of preterm infants.

Area of Science:

  • Neonatal critical care
  • Bioacoustics
  • Infant respiratory monitoring

Background:

  • Preterm and low-birth-weight infants frequently experience respiratory issues, including insufficient ventilation and apnea.
  • Infant crying, while communicative, can strain respiratory function and impact blood oxygenation in vulnerable neonates.
  • Acoustic analysis of infant cries is a non-invasive, cost-effective method linked to neuro-physiological status.

Purpose of the Study:

  • To develop and present a user-friendly software tool for analyzing the acoustic characteristics of newborn infant cries.
  • To enable robust tracking of key acoustic parameters in short, time-varying cry signals.
  • To provide high-resolution insights into cry signal features for clinical application.

Main Methods:
