Pure tones/Complex Sounds
A sine wave
What are pure tones graphed as?
Any influence that causes an object to undergo a change in speech, direction, or shape
What is force?
Maximum displacement from a position of rest
What is amplitude?
Amount of air that can be inhaled above Tidal Volume
What is Inspiratory Reserve Volume?
Changes fundamental frequency & is the main agent of regulating the human voice
What is the function of the cricothyroid joint?
The sound of a single frequency
What is a pure tone?
Resistance of any physical object to a change in its state or motion or rest (grams/kg)
What is Inertia?
Represents changes in air pressure
What is a waveform?
Air that remains in the lungs after a maximum exhalation
What is Residual Volume?
Affects the positioning of the vocal folds
What do the artyenoid cartilages do?
Waves that consist of 2 or more frequencies
What is a complex sound?
A force acting on a specific surface area (force/area)
What is pressure?
The time it takes for one cycle of vibration to occur (Frequency= 1/t)
What is a period?
Amount of air that can be exhaled below Tidal Volume
What is Expiratory Reserve Volume?
1. Lateral Cricoartyenoid Muscle
2. Interarytenoid
What are the adductor muscles?
Consist of a series of frequencies that are related to each other
What is a periodic complex sound?
How does air flow?
Number of cycles (of vibrations) per second
What is frequency?
Tidal Volume + Inspiratory Reserve Volume
What is Inspiratory Capacity?
Posterior Cricoarytenoid Muscle
What is the abductor muscle?
Consists of two or more frequencies, but they don't repeat
What is an aperiodic complex sound?
An INVERSE relationship between volume & pressure & a DIRECT relationship between pressure & density
What is Boyle's Law?
Pitch
What is frequency perceived as?
Interference that results in increased amplitude
What is construction interference?
Close during swallowing & effortful activities, open during phonation
What do the false vocal folds do?
