Laryngeal Function Studies
Laryngeal Function Studies are performed by Voice Pathologists who are specially trained to collect objective data using several sensitive instruments.
This information, combined with the eye and ear of the highly skilled clinician, provides a through and efficient means for evaluating voice disorders. This information is then shared with the Ear, Nose, and Throat Surgeon (ENT/Otolaryngologist). Decisions are then made for appropriate medical, surgical, or rehabilitative treatments.
Aerodynamic Voice Analysis
Aerodynamic Voice Analysis is a measure that demonstrates exactly how air from the lungs passes between and drives the vocal folds as the patient makes sound into an air transducer. Other measures include those that demonstrate the effort to drive the vocal folds for voice production. The efficiency of vocal fold movement before and after treatment can be assessed by these measures. There is no preparation for this testing procedure.
A number of acoustic properties of voice can be measured and analyzed by computerized instruments. As the patient speaks into a microphone, the instruments translate such factors as hoarseness, pitch, and loudness onto a visual screen display. They also measure, analyze, and display digital readouts of these properties. In addition, a spectrograph charts the patientís voice on paper. Similar to fingerprints, spectrographic voice prints are unique to each individual. All of these measures are used to aid in voice evaluation and treatment planning.
