Round table with Filipa Lã, Johan Sundberg and Brian Gill on defining subglottal pressure and its importance to voice.

https://unedvoicelab.com/subglottal-pressure/
Subglottal pressure ( Psub ) is one of the most influential physiological parameters controlling the voice quality. It refers to the overpressure of air in the respiratory system. Its main function is to vary vocal loudness, high pressure producing loud voice. Vocal loudness is commonly measured in terms of sound pressure level (SPL), measured

the minimum value of subglottic pressure required to achieve glottal separation is called the phonation threshold pressure. quality of voice. depends on symmetrical vibration at the midline of the glottis. loudness of voice. Influenced by subglottic pressure, glottic resistance, transglottic air flow, and amplitude of vibration

Joel: joeljameson20@gmail.com. JVS. Subglottic pressure is a complicated vocal anatomy term so let's break the word down.  The "glottis" part of the word refers to the opening between the vocal chords and "sub" part of the word mean beneath.  Pressure refers to the breath pressure coming up through the opening betwee.

The change in fundamental frequency with subglottal pressure in phonation is quantified on the basis of the ratio between vibrational amplitude and vocal fold length. This ratio is typically very small in stringed instruments, but becomes quite appreciable in vocal fold vibration. Tension in vocal fold tissues is, therefore, not constant over

where P max is equal to 7.5 cmH 2 O, an average level of subglottal pressure during sustained phonation. Because pressure exponentially increases in the capacitive model as it approaches P max, a transglottal pressure equaling 1% of P max was used as a theoretical endpoint for equilibration. This allows us to approximate the time required to fill the supraglottal volume, which can be done by

To regulate the subglottal pressure, you need to 1. not take in a full tank of air 2. use proper amounts of muscle tension (intercostal, oblique, dorsal, etc. They all play a role in mitigating the pressure and stabilizing the larynx. As for the diaphragm, its role is less voluntarily controlled) Now, to answer your questions: A.

https://pubmed.ncbi.nlm.nih.gov/17762273/
Subglottal pressure (SGP) is a valuable parameter in the research and clinical assessment of laryngeal function. The lungs serve as a constant pressure source during sustained phonation, and that pressure, SGP, can be used to determine the efficiency with which the larynx converts aerodynamic power to acoustic power. As the larynx serves as an

The PG-20 and PG-60 are handheld, battery-operated devices that give real-time estimates of the subglottal pressure Subglottal pressure, or Subglottic pressure, is the pressure that builds up beneath ("Sub-") the vocal folds. The amount of subglottal pressure generated is determined by the airflow through the leakage of air between the vocal folds and the resistance to that flow during

1.1. Traditional Methods of Subglottal Pressure Estimation. The direct measurement of Ps can be accomplished but is rarely performed due to its invasive nature, including tracheal puncturing for subglottal sensor positioning [30,31] or transglottal placement of pressure transducers [32,33].Traditionally, indirect methods of Ps estimation were cumbersome and included full-body plethysmography

The pathophysiology of subglottic stenosis depends on the underlying cause. For example, in endotracheal intubation (a traumatic cause of subglottic stenosis), the inflated endotracheal tube balloon causes pressure necrosis, ischaemia and ulceration of the mucosa. Subsequent scarring then causes circumferential stenosis of the subglottis.
