This study introduces a novel, noninvasive device for estimating subglottal pressure (SGP) during voice production. The device offers a quick, easy method for assessing laryngeal function and vocal efficiency.

Area of Science:

  • Laryngology
  • Speech Science
  • Biomedical Engineering

Background:

  • Subglottal pressure (SGP) is crucial for assessing laryngeal function and vocal efficiency.
  • Current SGP measurement methods are invasive or require extensive patient training.
  • Vocal efficiency (Ve) reflects vocal health by comparing acoustic to aerodynamic power.

Purpose of the Study:

  • To test a novel, noninvasive device for estimating SGP.
  • To provide an easy-to-use tool for clinicians and patients.
  • To enable rapid SGP measurement with minimal confounding factors.

Main Methods:

  • A new device noninvasively estimates SGP via mechanical airflow redirection.
  • Short airway occlusions (135 ms) minimize laryngeal reflexes.

  • In-trial pneumatic comparison provides immediate numeric output.

    • Main Results:

    • The novel device provides a rapid, noninvasive estimation of SGP.
    • Ease of use is highlighted for both clinicians and patients.
    • The method allows for immediate, objective SGP assessment.

    Conclusions:

    • This device offers a promising, user-friendly alternative for SGP measurement.
    • It facilitates objective assessment of laryngeal function and vocal efficiency.
    • Further research can validate its clinical utility in voice disorders.
