Summary

A novel noninvasive method uses a jugular microphone to measure subglottal pressure changes during voice production. This technique shows promise for clinical diagnostics and research, despite requiring correction for signal deviations.

Area of Science:

  • Laryngology
  • Acoustic analysis
  • Speech science

Background:

  • Accurate measurement of subglottal pressure is crucial for understanding phonation aerodynamics.
  • Existing methods for measuring subglottal pressure are often invasive and impractical for routine clinical use.
  • A noninvasive technique is needed for practical phoniatric applications.

Purpose of the Study:

  • To introduce and validate a noninvasive method for measuring subglottal pressure changes using a jugular microphone.
  • To assess the feasibility of this technique for diagnostic and therapeutic purposes in phoniatrics.

Main Methods:

  • A jugular microphone was placed on the skin of the jugular fossa to record subglottal signals.
  • Recordings were compared with simultaneous direct intratracheal measurements in healthy subjects.

  • A correction procedure was applied to account for signal deviations due to tissue transmission.

    • Main Results:

    • The jugular microphone technique, after correction, demonstrated high correlations and good agreement with direct intratracheal measurements.
    • Even without correction, the method showed utility for diagnosing conditions affecting chest resonance.
    • The technique provides valuable data for research in voice production.

    Conclusions:

    • The jugular microphone offers a valid, noninvasive approach to measuring subglottal pressure.
    • This method has potential as a diagnostic and therapeutic tool in phoniatrics.
    • Further validation with larger subject groups is recommended to strengthen findings.
