Exam 1 Flashcards
What does frequency measure?
- Rate of vocal fold vibration, expressed as cycles per second, or Hertz (Hz)
- A measure of pitch
What does intensity measure?
- Physical measure of sound pressure, reported in decibels (dB)
- Intensity and loudness go together
What determines phonatory quality?
How the voice sounds; a reflection of how well the two vocal folds work during vibratory cycle
What is dysphonia?
Umbrella term used to refer to a voice that is disordered
Breathy, hoarse, rough, jitter (rapid changes in frequency), diplophonic, shimmer
Define voice disorder
Individuals whose pitch, loudness, resonance, or phonatory quality differ significantly from that of persons of a similar age, gender, cultural background, and racial or ethnic group
Define resonance
Vibration of the air within the oral, nasal and pharyngeal columns, which affects the quality of voice
- causes: anatomical, neurophysiological, allergies/illness
Glottal fry
irregular vocal cord vibrations at the low end of a person’s pitch range that results in a “creaky” sounding voice
Behaviors that are considered vocal abuse
Talking in noisy environments Coughing or clearing the throat frequently Using caffeine products Yelling, screaming, cheering Giving speeches or lectures Spending time in smoky environments
Vocal nodules
Acute (bruises on VF) vs chronic (nodules thicken and harden like callouses)
Polyp
Appear similar to nodules but may have a stalk, similar to blisters
Vocal cord hemorrhage
Burst blood vessel in VF, often sudden and painful
Bowed vocal folds
Usually seen in aging, due to thyroarytenoid (VF) muscle weakness or atrophy, hypo functional
What is spasmodic dysphonia?
Light voice, strained, croaking, strangling, tremor- VF close at the wrong time so you can’t breathe
Describe 2 psychogenic voice disorders.
- Psychogenic disorders (nonorganic disorders)- result from or are linked to emotional and psychological characteristics
- Mutational Falsetto- (puberphonia)- describes a male child or adolescent who inhibits an inappropriately high voice
- Juvenile Voice Disorder- A disorder in which a woman maintains a juvenile voice into adulthood
-What is a laryngectomy? Why would someone need a laryngectomy?
- A procedure in which a person’s larynx is surgically removed (mostly occurs with advanced cancer)
Give 2 options for producing voice after a laryngectomy.
- Alaryngeal Communication A form of communication used by people who have no larynx. (no voice) - Electrolarynx - Esophageal speech - Tracheo-esophageal prosthesis
