Type of Loss
What qualifies as an air bone gap?
15 dB or greater difference between air conduction threshold and bone conduction threshold
At what level do you usually present WRS?
40 dB above SRT.
(this is when you use dB SL! 40 dB above SRT = 40 dB SL. So if their SRT is 40 dB HL, you are presenting at 80 dB HL OR 40 dB SL)
What tymp type would you get with a sensorineural hearing loss?
Type A
How do you instruct when finding AC thresholds?
Raise your hand when you hear a beep, even if it is very soft.
What was the first Disney cartoon to feature synchronized sound? (it also introduced Mickey Mouse!)
Steamboat Willie
What 2 signposts do we look for to classify a sensorineural hearing loss?
1) Bone conduction thresholds are not normal
2) No air bone gaps
How do you score SRT?
SRT: threshold! the softest level at which the patient can repeat a word 50% of the time
WRS: Tally number of incorrect words (multiply by 2 or 4 depending on amount of words used, then subtract from 100). The score is a percentage
What tymp type and equivalent volume would you get with a wax occlusion?
Type B, small volume
Plot twist! What are the 3 of the 5 tests done in an audiological evaluation? (hint: not counting otoscopy!)
Impedance
Air conduction
SRT
WRS
Bone conduction
What Shakespearean play is the Lion King based on?
What 2 signposts do we look for to classify a conductive hearing loss?
1) Bone conduction thresholds are normal
2) There is an ABG at 2 or more frequencies
What is crossover?
When a sound is heard in the better ear when testing the poorer ear
(sound is heard at a lower level than is actually being presented due to interaural attenuation: reduction in sound energy as it travels from one ear to the other)
What tymp type and equivalent volume would you get with a perforated TM?
type B, big volume
How do you instruct when doing impedance testing?
You will feel some pressure like you are going up into the mountains and hear some loud beeps. Your job is to sit quietly, this test is automatic, you don't need to do or say a thing.
Which real life actor is Aladdin's facial features modeled after?
Tom Cruise
What 2 signposts do we look for to classify a mixed hearing loss?
1) BC is not normal
2) There are ABGs at 2 or more frequencies
Why do we mask?
To ensure that the thresholds we get are the true thresholds, and not a result of crossover from the better ear.
(we may need to mask during AC, BC, and speech testing)
What tymp type would you get with Eustachian tube dysfunction?
Type C
How do you instruct for WRS?
"You will hear another list of words, they will not get softer. Please say the last word of each phrase. It is okay to guess."
What is the newest ride in Disneyland?
Tiana's Bayou Adventure
What type of hearing loss is not medically treatable?
Sensorineural hearing loss
What is the attenuator dial on an audiometer?
Changes dB level
What are 3 of the 5 impedance tests?
Tympanometry
Static Compliance
Equivalent volume
Acoustic reflex thresholds
Acoustic reflex decay
How do you instruct for SRT?
"Please repeat these words. *familiarize list* Now, they will get softer and softer. Please guess if you are not sure, it is okay to guess."
What ride at Disneyland has a basketball hoop inside the employee only area?
Matterhorn bobsleds
