Selecting a HA
A person has a mild-to-profound hearing loss. What hearing aid style would you recommend?
BTE
You are provided an audiogram showing current thresholds and aided thresholds. How do you determine the gain due to a hearing aid?
Take the aided threshold and subtract it from the unaided threshold.
What is the purpose of having a stethoset in your kit?
To judge the sound quality
Name one advantage of a BTE?
•Typically least expensive.
•Most durable, have low repair rates.
•Can get more gadgets on it. Can use an FM System.
•Most power out of the hearing aid. Greatest range of hearing loss (mild to severe).
•Less likely to have feedback. Squealing that happens when sound leaves the receiver and cycles back through to the microphone. Increasing the distance will decrease the likelihood of feedback. In a BTE the microphone and receiver are fairly far apart.

Name one advantage and one disadvantage of an ITE.

•Telecoils
Disadvantage: not as powerful as a BTE
A person has a mild-to-severe hearing loss. What hearing aid style would you recommend?

On an audiogram, vowels fall into what range of frequencies?

What is the purpose of having a dollar bill in your kit?

Name one advantage and one disadvantage of an ITC.
•Advantage: not as noticeable

•Cannothave as big of a volume wheel
•Options for circuitry are limited
A person has a mild-to-moderately severe hearing loss. What hearing aid style would you recommend?
ITC
Phonemes, such as /s/, /h/, and /f/ fall into what range of frequencies on an audiogram?
In the higher frequencies, about 1,500-6,000 Hz
What is the purpose of having Otoferm in your kit?
It helps the earmold fit more firmly. If an individual is getting feedback (earmold too loose), you can glop some on the hearing aid.
Name one advantage and one disadvantage of a CIC?
Advantages:
•Not as noticeable (cosmetic concerns)
Disadvantages:
•Cannot fit a directional microphone, which helps with cancelling background noise.
•Not as powerful
•Small batteries don’t last as long/batteries hard to manipulate if dexterity problems
•More expensive
•Cannot use assistive listening device with.
•Susceptible to wax
•Not as durable.
A person has a mild hearing loss. What hearing aid style would you recommend?
