Audiology Exam Review Flashcards

Flashcards for audiology exam review

Zinc air battery

Battery type with a 5-7 day lifespan.

Lithium ion battery

Battery type that requires nightly recharge.

Speech reading

Using visual cues to understand speech.

Necessary practice before leaving the office after HA fitting

How to put in/take out the HA & how to change the battery/insert into charger.

Patient feedback on HA sound quality

Subjective test for HA verification; simply ask the patient how the HAs sound.

Infrared system

Better use for large theaters/churches where there isn't always direct line of sight and little sunlight.

Telecoil

Picks up electromagnetic info instead of acoustic info.

Anticipatory strategies

Communication strategies to anticipate potential communication challenges.

First two things to check on a dead HA

Battery and Filter.

Three measurements of a HA matrix

Output, Gain, and Slope.

Hearing aid for a 3-year old with moderate to moderately severe SNHL

BTE with EMs (and child proof battery door!).

I + G = O or O - I = G

Equation for the relationship between gain, output, and input.

HA fitting for a middle aged women who is not often in noisy situations but would like to not strain as much when in small group settings

IIC or CIC.

Assertive communication strategy

Telling the cashier to speak up and slow down because you have hearing loss.

Two basic components of a HA that is a transducer

Microphone and Receiver.

Repair strategies

Repetition, Clarification, Spelling, Writing

Five basic components of a HA

Microphone, Amplifier, Receiver, Volume control, Power source

Communication strategy that would best benefit a pt who no longer goes out with more than 1 friend at a time because they cannot hear in group settings

Being assertive.

What speakers can do to help person with HL

Where the hearing impaired sits in the table, outside seating in a quieter areas, area with more light.

Two ways to monitor a HA

Ling 6 sounds and listening with stethoscope.

SSPL90

Measures output we ordered.

Loop system

Sound enters speaker’s mic and is sent to a wire around the carpet or ceiling. The wire uses electromagnetic energy to transmit sound. HA must be in telecoil mode.

Gold star for objective testing when we verify a HA is fit appropriately

Real ear measurements.

What is threaded into the cochlea for CI patients to replace the inner hair cells?

Electrode array (currently 22 electrodes).

Reasons speech reading is a better tool for the hearing impaired rather than a way to compensate for their HL

Speed of speech, homophenous nature of speech sounds, many speech sounds do not come with visual information.

All of the Ling 6 sounds

ah, oo, ee, sh, s, m.

MiniRITE

bluetooth or telecoil for better hearing in classroom, but smaller and more subtle than BTE.

Gain

Measures output we ordered. Input 50 dB SPL and measure output, then use equation to find gain.

Equivalent input noise

Makes sure circuitry isn't abnormally loud. Input 0 dB SPL and measure output.

Distortion

Gives percent of distortion created by HA. Input sound at 3 frequencies and see if there are responses at other frequencies.

Why do we do UCL testing?

To ensure we do not set the MPO to an uncomfortably loud or damaging level
