Phonatory Aerodynamic System (PAS)

A comprehensive airflow system for the voice lab

The Phonatory Aerodynamic System (PAS) provides voice clinicians and researchers with a complete hardware/software system for measuring airflow and pressure parameters related to speech and voice production. Based on years of experience with aerodynamic instrumentation, PAS was designed at KayPENTAX with input from leading clinicians and voice scientists.

The PAS hardware was ergonomically designed for ease of use in speech/ENT clinics and voice labs. Measurements include, among others, average phonatory flow rate, sound pressure level, fundamental frequency, vital capacity, subglottal pressure (derived), glottal resistance, and efficiency parameters.

Many clinics routinely collect imaging (e.g., stroboscopic or high-speed video data) and acoustic data when evaluating patients. The measurements obtained from PAS complement these imaging and acoustic analysis data for a more comprehensive profile of patient performance that can be tracked from initial evaluation through intervention. PAS was designed to integrate well with the other KayPENTAX acoustic products with common data format and user interface.
