General Acoustics
100
Air pressure that builds under the closed vocal folds
What is subglottal pressure?
100
Muscles that make up the vocal folds, primary source of vibration during phonation
What are Thyroarytenoids?
100
Anything that gives you a visual representation of sound
Define spectrum
100
It acts to either depress/lowers the velum or raise the back of the tongue
What is the function of the Glossopalatine?
100
The study of sounds
Define acoustics.
200
Force exerted at the level of the vocal folds to resist the air pressure building below the folds
What is glottal resistance?
200
When contracted, they rotate the muscular process backwards causing the vocal processes of the arytenoids to rotate laterally, pulling the vocal folds open.
What is the Posterior Cricoarytenoid Muscles function?
200
Time by amplitude (displacing of the medium (air))
What does waveform show?
200
It acts to lower the velum or to reduce the distance between the pillars through a sphincter-like action
What is the function of the Pharyngopalatine?
200
Processed vibration
Define sound.
300
As a space narrows, air passing through that space moves more rapidly
What happens during the venturi effect?
300
When contracted, they rotate the muscular process forward, causing the vocal processes to rotate medically, closing the vocal folds.
What is the Lateral Cricoarytenoid Muscles function?
300
Time
What is represented on x axis?
300
Bulk of the velum that acts to lift the velum up and back and open the Eustachian tube
What is the function of the Levator Palatine?
300
Movement
Define vibration.
400
Velocity of airflow passing through the glottis increases, the pressure between the folds decreases. Sometimes referred to as the "vacuum" effect. Basically, the Venturi Effect causes the Bernoulli Effect.
What is the Bernoulli effect?
400
Two arytenoids that are held together "straight across" laterally and "top to bottom" anteriorly and posteriorly. This action is essential to the stable adduction of the vocal cords.
What are the Interarytenoid Muscles?
400
Amplitude
What is represented on the y axis?
400
This muscle acts to shorten and lift the velum
What is the function of the Uvular Muscle?
400
How it is produced, transmitted, and perceived.
What elements do we consider when talking about sound?
500
The space between the vocal folds
What is the glottis
500
Muscles that include two bundles on each side of the larynx. When contracted, they rock the thyroid down and slightly forward. Causing the thyroid to be pulled away from the arytenoids, stretching the vocal folds. This is a major factor in increasing the tension of the vocal folds for pitch changes.
What are the Cricothyroid muscles?
500
Discontinuous, continuous line, 3D, waveform
Which spectra look at voice?
500
It acts to flatten and tense the velum and open the Eustachian tube.
What is the function of the Tensor Palatine?
500
Air, solids, and liquids.
What are the medians that sound is transmitted?
