Quiz 1
| 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 |
