Question | Answer |
---|---|
When air particles are close together | Compression |
The source of sound is something that | causes vibration |
In wave propagation, the individual particles move | back and forth a short distance |
Speech and hearing scientist use the waveform to represent the pressure wave. The peak on the waveform represents periods of | Compression |
The height of a waveform represents | Amplitude (How loud) |
Hertz measures | Frequency (Cycles/sec.) |
T/F All sounds in English have approximately the same pitch | false |
T/F The human voice is an example of a simple sound wave. | false |
Examples of complex sounds | Periodic & aperiodic sounds |
T/F The tympanic membrane functions most efficiently when it is very tight. | False |
3 resonance cavities relevant to speech | Pharynx, oral, naval |
The phonatory system is primarily represented by which anatomical structure. | Vocal folds |
Pull vocal folds apart | Vocal fold abductors |
2 primary ways of increasing amplitude | increasing vocal fold aDDuction & increasing breath support. |
125 Hz is the average fundamental frequency of | men |
If you stretch your vocal folds, your speech will | get higher in pitch |
Bring vocal folds together | vocal fold adductors |
Primary muscle of inhalation | the diaphragm |
T/F The primary function of the vocal folds is to produce sounds. | True |
T/F Speech breathing is no different than regular breathing in terms of inhale/exhale ratio. | True |
An intermediary connection between the tongue and the larynx. | epiglottis |
T/F Vocal fold sit on top of the trapea | true |
The 4 systems of speech production | Respiratory, phonatory, resonance, articulatory |
Respiratory | LUNGS |
Phonatory | LEVEL OF VOCAL FOLDS |
Resonance | "THE MEGAPHONE" (pharynx, mouth, & nasal) |
Articulatory | STRUCTURES (tongue, teeth,...etc.) |
T/F The diaphragm is shaped like a parachute. | True |
Closes off the larynx | Epiglottis |
Resonating chambers | Throat, mouth, nasal |
What do resonating chambers do? | Alter sounds & act like a megaphone |
T/F Vocal folds are inside the thyroid cartilage | True |
Word assigned to space between the vocal folds | Glotus |
Frequency determines | What pitch. |
Quality determines | How healthy and harsh. |
Amplitude determines | How loud. |
Tighter vocal folds = | Increased pitch |
Sound waves= | pressure waves |
Physical sound | Creates vibrations |
Perceptual sound | goes into ear canal |
2 requirements for sound | Vibration & medium |
Through which sounds can propagate | medium |
T/F Any singular molecule travels in its own distance. | True |
T/F Air particles are not displaced over a large distance. | True |
Amplitude | Loudness ( Decibels & pascals) |
Like a rubber ducky- muscle action pulls open lungs, sucking air in. | Inhalation |
20-25db= | Good hearing! |
Regular pattern of pressure & speed | Periodic |
Random variation in pressure and speed | Aperiodic |
Complex sounds can be | Periodic or aperiodic |
A 3 dimensional representation of speech used to analyze sounds | Spectogram |
3 dimensions of speech | time, frequency, loudness |
Pushing air particles out of lungs | exhale |
Causes the vibration ('Source of Sound") | Phonatory system |
Major components of the phonatory system | Larynx, hyoid bone, vocal folds |
Only bone that doesn't attach to another bone. Important for swallowing. | Hyoid bone |
Fundamental frequency | Hertz, Mass/unit length, Cricothyroid muscle |
Pull and stretches vocal folds | Cricothyroid muscle |
Lowest pitch we can make | Fundamental frequency |
Mass/Unit Length | thicker vocal folds=lower pitch |
Rate of vibration per/sec | Pitch |
215 Hz is the average fundamental frequency of | women |
2 catagories of hearing loss | Sensorineural & Conductive |
Hearing loss when there is fraying of hairs. (most common, age related) | Sensorineural |
Hearing loss when there is fluid in ear. (hearing wave) | Conductive |
