The part of the basilar membrane tuned to low frequencies
What is the apical end of the basilar membrane?
The first test you should do in any audiology appointment
What is otoscopy?
An audiology YouTuber who is all about Best Practices
Who is Dr Cliff, AuD?
When thresholds increase 5 dB when any noise is presented in the NTE, even if cross-hearing is not possible
What is central masking?
The best earmold material for a person with very thin skin
What is acrylic?
The equation to calculate dB from pressure
What is dB=20log(p/p0)?
The test you should use for a suspected nonorganic unilateral hearing loss
What is the Stenger test?
These two associations offer certification and set the standards for audiology practice in the US
What are AAA and ASHA?
The three requirements to use Yacullo's simplified approach
What are no ABG's, good PTA/SRT agreement, and moderate presentation level re:SRT?
The FDA Red Flags (name 4)
What are visible congenital/traumatic deformity, pain, drainage, sudden hearing loss in the last 90 days, dizziness, ABG >10 dB at 500, 1000, and 2000 Hz, unilateral hearing loss, cerumen impaction/foreign body in the canal?
The 4 phases of an action potential (with action/membrane potential)
1. Resting | Na+/K+ pump | -70 mV
2. Depolarization | Na+ in | increases
3. Repolarization | K+ out | decreases
4. Hyperpolarization |K+ out | decreases below resting
The gain setting to test equivalent input noise, total harmonic distortion, frequency response curve, and battery drain
What is reference test gain?
Mild hearing loss increases your risk by 20%, moderate by 30%, and severe by 50%
What is dementia?
The bone conduction mechanisms for the outer, middle, and inner ear, respectively
What are osseotympanic, inertial, and compressional/distortional?
The gold standard for hearing aid microphones
What are electrets/or MEMs?
This olive encodes ITDs using excitatory input from both ipsilateral and contralateral sides
What is the MSO?
The steps to a good ear impression for a custom hearing aid
What are: visualize, place oto-block, visualize again, mix material and syringe smoothly without cake decorating, mark horizontal, allow to cure, remove by twisting forward, visualize again, document
The year the AuD became the entry-level degree to practice audiology in the US
What is 2007?
Using the mid-masking approach and inserts, what is the masking level for a presentation level of 70 dB with thresholds of 10 dB in the NTE and 40 dB (best threshold) in the test ear? (Assume no ABGs)
What is 52.5 dB?
The plumbing modifications that affect high, mid-, and low frequencies, respectively
What are sound bore/canal length, dampers, and venting?
The shape of these is influenced by the strength of inhibition at high SPLs
What are rate-level tuning curves?
Site of lesion for this reflex pattern:
R contra: WNL

L contra: Absent
L ipsi: WNL
What is the SOC & VII nucleus?
250 points: the cough reflex in our ear
500 points: the nerve stimulated that triggers this reflex
