Aap Flashcards
Soundproduction
Power souce - lungs
Oscillator - something that vibrates
Resonator - air and spaces vibrating
Larinx functions
Respiration, regulate airflow
Protections swallowing
Thoracic fixation abdominal pressure
Phonation
Functions intrinsic muscles
Opening glottis abducting vf
Closing blotting adducting vf
Lengthening vf
Shortening vf
5 layers of vf
Epithelium
Laminate propia SLP ILP DLP
Vocalist muscle
Functions of the palete
Hard, separate nasal and mouth passage
Soft, close nasal passages
Swallowing by closing and raise tongue
Functions of breathing
O2 to cells
Expell CO2 from lungs
Power source for sound
Breath support
Normal = in, active and out passive
Singing = both active
Internal intercostal muscles and diaphragm control outflow of air
Bernoulli principle
Increase of speed in liquid of gas is a decrease in pressure
Changing pitch
Vf length, high is long
Vf mass
Vf tension
Changing volume
Increase subglottal pressure
Increase in medial compression
Misuse and abuse of voice
Scream, talking to high and loud, excessive voice use, whisper, noisy surrounding, cheering, throat clearing of coughing, heavy singing without warmup, speaking on phone
Hydration and dehydration
Hydrated mucosa can vibrate better
Makes mucus on chords thinner
Dehydration raises PTP
Dehydrators: caffeine, alcohol, sugar, planes, airco, central heating
Smoking alcohol and reflux effects
Smoking is reinkens oedema and low frequency
Alcohol is dehydration
Reflux is hoarseness and vocal fatigue
Causes swelling interarytheniod area
Granulomas can occur
Redding of arythnoids
Cold prevention
Wash hands
Carry sanitiser
Don’t pick nose
Good general health
Vit D
Wrap up in cold weather
Nose wash
Working of Lax Vox
Higher pressure vocal tract
Balanced vocal alignment
Lowering pitch in which air can vibrate
Massage chords, reduce swelling, treats reinkes oedema
PTP
Phonetic threshold pressure
Minimum pressure to make a sound
Muscle action in registers
Pull down larinx
Thyroid c. Forward for height
Open throat
Falsetto is extrinsic muscles stretch
Headvoice upward pull from the elevators
