SHS exam 2 Flashcards
Bernoulli effect and def and some notes
Know how it affects our air flow and pushes our air up and out. What sustains us for phonation has to do with fundamental frequency (opposites)
Number for males, females, and children frequencies
male - around 125 Hz
female - around 225 Hz
child - around 300 Hz
When we produce a sound from our vocal folds, it is …
periodic, not aperiodic
Know frequency and pitch and how they relate… if one decreases, what happens, and if one increases, what happens
frequency is the number for pitch, if frequency increases, pitch increases, if frequency decreases, pitch decreases
what goes with amplitude
loudness
Hyoid bone
lies between jaw and larynx
what are the three cavities
Nasal, oral, pharyngeal
Epiglottis
flexible cartilage that covers larynx during swallow
Thyroid cartilage
encloses larynx anteriorly
Arytenoid cartilage
paired pyramidal structure, vocal processes run forward to attach to vocal folds
Cricoid cartilage
top ring of trachea, supports arytenoids
Know the two sources of sound production for speech
phonatory source - air pressure make VF vibrate
supraglottal source - stops and fricatives
Arytenoid cartilage abducts and adducts; know which muscles do those functions
abduction - posterior cricoarytenoid muscles (PCA)
adduction - interarytenoid muscles (IA)
Glottis (def and what is it by)
glottis is the part that opens and closes for phonation. it is in between the supraglottis and subglottis
Myoareodynic theory def
There is a relationship between the aerodynamic properties, subglottal pressure, and transglottal flow as they interact with the resistance and elasticity of the vocal tissues.
Longer vocal folds give a … fundamental frequency
lower
if vocal folds are tense, the fundamental frequency is …
higher
vocal folds that have more mass will be …fundamental frequency
lower
Know what the larynx functions (biological and nonbiological)
protection/keep out foreign objects, vibration for speech sounds
Phonation, clinically, what issues will occur because of atypical muscles and structures
cleft palate, may have trouble producing words and can then affect language. Too many sinus infections can lead to misunderstanding and comprehending spoken language
Know the different types of waves (transverse and longitudinal and simple/single wave)
transverse - particles in the medium move perpendicular to the direction the wave travels
longitudinal - particles in the medium move parallel to the direction the wave travels
simple - pure tone and only one frequency
opposite of a complex wave
simple/single wave
know the two disorders that can affect phonation
stuttering and spasmodic dysphonia (VF paralysis yields inability to maintain phonation (strangled voice quality)
