| When does Otitis Media Occur? | Result from Eustachian tube dysfunction |
| What are Ventilation Tubes? | when the eustachian tubes are not able to function a Ventilation Tube is surgically implanted to ventilate the middle ear cavity also ear plugs may be necessary to protect the tubes |

| What is Otology? | The branch of medicine devoted to the study, diagnosis and treatment of diseases of the ear and related structures |
| When did the the asha develope the new discipline of audiology? | 1947 |
| What is Aural Rehabilitation? | The treatment of those with hearing loss that has begun after birth usually after speech and language development to improve overall communication ability |
| When was AAA developed | An organization founded in 1988, of, by, and for audiologists |
| Name some Professional Associations? | American Auditory Society, American Academy of Audiologist, Academy of rehabilitative Audiology, American Speech Language hearing Association |
| Name the three different types of hearing losses. | Sensorineural, Conductive, Mixed |
| What does the word of Audiology Mean? | The study of hearing |
| What organization was the first to help found Audiology? | ASHA |
| What is another name for Sensorineural Loss? | Nerve Loss |
| What is the most common Hearing Loss? | Sensorineural Loss |
| What is the only way to help fix a sensorineural loss ? | hearing aid |
| Where is the damage when there is a Sensorineural loss | inner ear (Hair cells) |
| What hearing loss is most common in children? | Conductive hearing Loss |
| Which hearing loss affects the ability to understand the words using Clarity ? | Sensorineural Loss |
| What hearing loss effects volume? | Conductive Loss |
| What part of the ear is affected during a conductive heraing loss? | Nerve is fine middle and outer ear may be damaged |
| What is the least common hearing loss? | COnductive Hearing Loss |
| What kind of test would you do if you could not do a hearing test on the spot? | Tuning Fork test |
| What hearing loss is considered to be medically | Conductive hearing loss |
| how does a pitch change for a tuning fork? | the length of the tuning fork affects the pitch of the tuning fork |
| Name three types of tining fork test? | rinne, bing, and weber |
| Out of all three test which is most common? | Rinne |
| When performing a Rinne what is being compared? | The Bone Conduction and Air conduction are being compared by sticking the Fork on the Mastoid Bone |
| What is Normal Hearing When Performing a Rinne Test? | The Noise is louser by AC rather than BC |
| Postive= | good hearing |
| If a person has a Conductive hearing loss during a rinne test how could you be able to tell? | Bone conduction will be louder than Air Conduction |
| If there is a Sensorineural Loss during a rinne test how could you be able to tell? | The BC and AC are equal |
| When performing a Weber the tuning fork goes where? | The middle of the forhead. |
| If a patient has a conductive or sensorineural loss. How would you be able to tell which one it is using a weber? | COnductive: goes to worse ear Sensorineural: goes to better |
| what is the saying about middle and inner ear? | o The tone will lateralize (go to) the better inner ear or the worst middle ear. |
| What is the bing test? | You press a tunning fork up against the tragus and see if it pulsates .. if the tone pulsates then the patient has normal hearing if the tone does not than there is a conductive loss |
| What is Audiometry? | - Pure tone audiometry is a behavioral test measure used to determine hearing sensitivity that measures involves te peripheral and central auditory systems pure tone threshold (PTTs) indicate the softest sound audible to an individual at least 50% of the time hearing sensitivity is plotted on an audiogram which is a graph displaying intensity as a function of frequency |
| What is an Audiogram? | a chart that represents a patients hearing by frequency and intensity |
| What is Frequency measured in? | Hertz |
| Frequency coralates with what? | Pitch |
| red and blue correlate with what ears? | Red: Right Blue: left |
| what is something that might colapse the ear canal? | supra aural headphones |
| what is intreaural and supra aural attentuation? | 40dB= Supra 60dB= Intra |
| name the Air COnduction Pathway? | Outer, Middle, Inner, Nerve Cortex |
| Bone Conduction transducer helps test what? | Bone conduction |
| how do you use a bone conduction transducer? | attach it to the mastoid or for head |
| When testing for bone conduction what are you really testing? | Inner nerve and cortex because it by passes the middle and outer ear. |
| Why Is Pure tone audimoetry subjective? | becuase you depend on the patient to tell you when they hear the sound |
| what octaves do we test patients at for frequency? | 250, 500, 1000, 2000, 4000, 8000 |
| when testing the intensity what method do we use? | down 10 up 5 method |
| What is threshold? | the lowest sound a patient can hear 3 times in a row |
| does frequency or intensity tell us what type of hearing loss the patient has? | intensity |
| The letter X stands for which ear? | Left |
| The letter O stands for which ear? | Right |
| what type of waves do audiologist use when dealing with sound? | Sine Waves |
| What is Localization? | a difference of 10db between both ears |
| What is a conductive hearing loss? | Ac has a hearing loss BC does not have one |
| What is a Sensorineural Hearing loss? | AC and BC have a hearing loss with no air bone gap |
| There is no such thing a difference in ________ dB air bone gap? | 60dB |
| Whend oes cross over happen? | after intenuation |
| When do you use a tympanigram? | If there is fluid behind the middle ear |
