Assessment

Question 1

Air conduction audiometry answers two questions:

Answer 1

• Does a hearing loss exist?
• If yes, how much? (degree)

Question 2

In AC audiometry, the sound travels through air and reaches our outer ear and must travel through entire system. True/False, why do we care about this?

Answer 2

TRUE
- Any break in the chain of hearing from outer, middle, inner and central will cause air conduction results to be abnormal.

Question 3

What is the main point of AC audiometry?

Answer 3

To assess the integrity of the entire auditory pathway.

Question 4

True/False: Pure Tone audiometry is the gold standard for diagnostics

Answer 4

TRUE

Question 5

Is Purre Tone Audiometry a subjective or objective test?

Answer 5

Subjective, it is a behavioral test

Question 6

True/False: You can only test PTA with insert earphones.

Answer 6

FALSE
- You can use a soundfield, insert earphone, or headphones.

Question 7

In PTA Daignostic testing, you are looking at…

Answer 7

• Thresholds
• The full battery of testing for confirmation of AC results.

Question 8

What are thresholds?

Answer 8

The softests sound they can hear, 50% of the time.

Question 9

What is an Audiogram?

Answer 9

A graphical representation of results
- A “picture” of your hearing

Question 10

PTA: Humans hear much more than the audiogram displaus (20 Hz to 20,000 Hz), from..

Answer 10

Base to apex

Question 11

In PTAs…

Shows:
It’s an average of:
They should match up with:
They only test:

Answer 11

• Shows speech frequencies
• PTA is just an average of speech frequencies
• They should match up with SRTs (within + or - 10dB
• Only tests certain frequencies because it’s where speech falls

Question 12

Give Degree of Normal

Answer 12

0-25dB

Question 13

What does Bone Conduction Audiometry answer?

Answer 13

• What type of hearing loss is present
• Integrity of the cochlea (inner ear)

Question 14

True/False: In Bone conduction audiometry, the better cochlea is the one that responds.

Answer 14

TRUE

Question 15

True/False: In BCA, we hope that BC is within 15 dB of AC

Answer 15

FALSE
- Within 10 dB

Question 16

Is BCA an objective or subjective test?

Answer 16

Subjective- it is a behavioral test

Question 17

When it comes to assessment, it is not necessary to provide the instructions to the patient.

Answer 17

FALSE
- INSTRUCTIONS ARE IMPORTANT

Question 18

List the characteristics of NHL

Answer 18

AC < 25
BC < 25
Type A tympanograms
No occlusion
No ABG

Question 19

AC vs. BC
- If there is not a difference of > 10 dBHL, the result is

Answer 19

SNHL or Normal

Question 20

AC vs. BC
- If there is a difference of >10 dBHL, the result is…

Answer 20

CHL of MIXED
- If BC thresholds are normal = CHL
- If BC thresholds are not normal = MIXED

Question 21

List the characteristics of SNHL

Answer 21

AC > 25
BC > 25
Type A
Clear
No ABG

Question 22

What is the most important result in an audiogram? Why?

The:
Because our daily acitivity of..

Answer 22

The Speech Audiometry
- Allows us to analyze
- Because our daily activity of listening is not composed merely of beeps, but is a complex neurological process called speech perception

Question 23

Speech audiometry provides…

Answer 23

A tool for identifying the impact hearing loss has for a person’s communication
- You are looking for consistency.

Question 24

What are the stimuli in speech audiometry?

Answer 24

MAIN: Phonetically Balanced Words
- Spondee words
- Sentences
Nonsense-words

Question 25

How do you find threshold in SRTs/ SDTs

Answer 25

By using spondee words

Question 26

True or False: SRTs should be in agreement with PTAs

Answer 26

TRUE
