| Question | Answer |
|---|---|
| An infant is sitting in the sound booth with her mother. Sound is presented through the loud speakers. The audiologist watches for the presence of consistent responses to sound by the infant. This is measurement is called | BOA Behavioural Observation Audiometry |
| Acoustic Immittance is a term referring to a series of tests to determine the status of the middle ear. Name all three Immitance tests. | tympanogram, static compliance, acoustic reflex |
| tympanogram | a graphic representation of the relative compliance and impedance of the tympanic membrane and ossicles of the middle ear obtained by tympanometry. |
| static compliance | mobility of the tympanic membrance (TM) in response to air pressure in the ear canal |
| acoustic reflex | the stapedius muscles contracts reflexively in response to intense sounds, causing the TM to stiffen |
| When a brief sound is presented that is loud enough to cause damage to the inner ear, what muscle responds? | Stapedius-reflexively dampens vibrations of the stapes by pulling on the neck of that bone. prevents excess movement by the stapes, helping to control the amplitude of sound waves and your own voice from the external environment to the inner ear. |
| tensor tympani muscle, | primarily dampens those sounds associated with chewing. |
| Where in the cochlea does the surgeon place the elactrode array | scala tympani |
| Scala tympani | The purpose of the perilymph-filled scala tympani and scala vestibuli is to transduce the movement of air that causes the tympanic membrane and the ossicles to vibrate, to movement of liquid and the basilar membrane |
| organ of corti | The organ of Corti is the sensitive element in the inner ear and can be thought of as the body's microphone. |
| A young child does not respond to sounds consistently. pure tone test shows a reverse slope, severe rising to mild bilateral hearing loss. ABR shows abnormal and present OAE what does child have | Auditory neuropathy |
| Behavioral testing in the booth tests hearing from | 250 Hz to 800 Hz |
| A click ABR tests hearing from | 1500 to 4000 Hz |
| Which of the following syndromes are not associated with hearing loss | **Dwarfism** Usher's Syndrome CHARGE Pierre Robin |
| Mom takes her young hearing impaired son into the audiologist for a hearing test. His testing in the booth indicates thresholds 25-30 dB lower than previous testing. His typmanogram is type B what should the audiologist do? | refer to ENT for otitis media |
| An audiologist for a five year old child with a severe bilateral hearing loss who is having difficult discriminating the /sh/ from /f/ would likely first recommend which of the following | A frequency transposition hearing aid |
| What is the critical distance from the speakers of a sound field system in a classroom setting | 3 meters=1 foot |
| A probe REAL ear measurement is done by inserting a soft silicone tube into the ear canal with the child's earmold in place. The microphone at the end of the tube picks up the amplified sound and is sent to a sound processor and digitally displayed. | Tells the audiologist what the shape, length and diameter of the child's ear canal is doing to the amplified signal. |
| The cochlear implant replaces the function of the Organ of Corti where damaged or missing hair cells cause senory-neural hearing losses. In what part of the cochlea is the Organ of Corti | scala media |
| The pure tone average (PTA) is determined by an averaging the thresholds at the following frequencies | 500, 1000, 2000 |
| Speech Reception Threshold (SRT) | The use of familiar two-syllable spondee words by a hearing healthcare professional to assess the lowest intensity level at which an individual can repeat the words more than half of the time. |
| Semicircular Canals: | The three fluid-filled tubes in the vestibular portion of the inner ear that helps with equilibrium and the interpretation of the body's position. |
| Speech Awareness Thresholds (SAT) | the lowest sound intensity at which speech can be detected |
| The audiologist wants to know the softest level a young child can respond to speech stimuli. He may call the child's name, say buh-buh-buh, or make raspberries. These thresholds should be in agreement with pure tone thresholds. This is called | Speech Awareness Thresholds (SAT) |
| This test is a closed-set discrimina tion task in which the child must identify the stimulus word from a set of six pictures. This task is more difficult than the majority of other closed set discrimination tasks in that the vocabulary level is higher | Word Intelligibility by Picture Identification (WIPI) |
| The most important organ in the vocal tract is the | tongue |
| Nasal sounds are produced by directing the breath stream through the nose. This is done by lowering the velum creating an opening to the nasal cavity from the throat called the | Velo-pharyngeal port |
| Manner refers to how a consonant sound is produced. Which group of consonants below have the same manner | 1. /b/,/p/,/m/,/w/ ***2. /h/,/f/,/v/,/s/,/z/,/sh/ fricative** 3./t/,/d/,/s/,/z/,/n/,/l/,/r/ 4. /k/,g/g,/h/ |
| Place of production is where the sound is made. Which of the following sounds are made with the tongue in contact with he alveolar ridge just behind the upper front teeth? | /t/,/d/,/n/,/s/ |
| Which of the following statements are true about vowels | They carry most of the prosodic information and convey the emotion of the speaker. They give personal information about the speaker. The relative duration of vowels help differentiate voiced and voiceless consonants. |
| Which vowels should be taught first as they are the easiest to produce | Central vowels 1st Back 2nd Front 3rd |
| Front vowels are easiest to see and most difficult to hear. They require more precise tongue movement than others. Which vowels are front vowels | /æ/(as in and),/E/(as in then),/e/(as in Take),/I/(as in his),/i/(as in ease) |
| I am a lingua-velar plosive The velo-pharyngeal port is closed. The back of the tongue touches the velum where it joins the hard palate closing off the vocal tract.breath released into vocal tract as a plosive burst. F1 at 200-300 Hz and F2 at 1500-2000Hz | the letter /g/ |
| I am a voiceless lingua-dental fricative. The welo-pharyngeal port is closed. A continuous breath stream is emitted between the tongue and teeth. I have only one frequency band at 6000Hz what am I | /θ/ as in thumb |
| I am a nasal lingua-velar. The velo-pharyngeal port is open. The back of the tongue is elevated to the palate and the tip of the tongue rests behind the lower front teeth. 3 frequency bands, 1 at 300, 1 at 1200 1 at 2700Hz what am I? | /ŋ/ as in sing. |
