Phonation
In this lab, you will be listing, describing, and contrasting a number of respiratory functions and disorders, doing a variety of activities to help your understanding of respiration.
Explain how the vocal folds adduct and abduct. Describe all the relevant structures involved (cartilages, joints, muscles).
How is the mucosal wave generated and what is its significance?
Explain the Bernoulli Effect.
Take a rubber band and pluck it. Stretch it further and pluck it again. Now stretch it as far as possible and pluck it once more. What happened to frequency when tension increased? What role does mass play here?
The Fo and harmonics of the human voice can be well visualized on a line spectrum. This is known as the glottal spectrum and has a spectral slope. Draw a Fo of 125 Hz with successive harmonics that decrease in amplitude at a rate of 12 dB per octave. Make sure to label your axes correctly and completely.
Explain the relationship between voice quality and vocal registers, including a discussion of the physiological and acoustic parameters of…
Pulse:
Modal:
Falsetto:
Compare and describe each of these terms and the type of information that each provides regarding vocal fold vibratory patterns.
Jitter:
Shimmer:
NHR:
Choose a vocal disorder and compare the types of information that can be obtained about vocal function with acoustic, electroglottographic, and endoscopic measures.
