Subglottal Pressure Monitor from Glottal Enterprises, Inc.

1201 E. Fayette St. Syracuse, NY 13210

Company Profile
Handheld device that estimates subglottal pressure during speech or singing.
The PG-20 and PG-60 are handheld, battery-operated devices that give real-time estimates of the subglottal pressure during speech or singing. Knowledge of the subglottal pressure driving the laryngeal voice source is very important in understanding the operation of the voice. The PG-20 and PG-60 uses an intraoral pressure interpolation technique to measure subglottal pressure non-invasively. To make it easier to record a meter reading, the unit has a HOLD function. Pushing and holding down the HOLD button during or just after an utterance will cause the meter reading to remain at the value it was at the instant the button was pushed.
The PG-20 measures up to 20 cm H2O and the PG-60 up to 60 cm H2O.
