Question 4

For Pitch, where is it located on a graph and what is the lowest frequency and highest frequency?

Answer 4

1. At the top
2. Lowest = 125
3. Highest = 8000

Question 5

What’s the numbers for loudness in decibels (dB) aka on an Audiogram?

Answer 5

-10, 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120

Question 6

For Loudness, where is it located on a graph and what is the quieter and louder decibel for loudness?

Answer 6

1. On the left side
2. -10 is quieter
3. 120 is louder

Question 7

For Normal Hearing in a child and an adult what is the range?

Answer 7

Child - up to 20 dB

Adult - up to 25 dB

Question 8

As you go down the graph, what occurs?

Answer 8

Hearing gets worse

Question 9

What are the names of the degree of Hearing Loss?

Answer 9

1. Normal
2. Mild
3. Moderate
4. Moderately-Severe
5. Severe
6. Profound

Question 10

Answer 14

71-90

Question 15

For Profound HL, what is the dB HL Range?

Answer 15

Anything greater than or equal 91

Question 16

Looking at an audiogram, what are the important variables one should know?

Answer 16

1. Which ear sound was presented to
2. Frequency of sound that was presented (Hz)
3. The intensity of sound that was presented (dB HL)
4. The method sound presentation

Question 17

What is Audiology Color Coding?

Answer 17

RED RIGHT ROUND = CIRCLE

BLUE LEFT X = X

Question 18

Define unmasked

Answer 18

Its sound presented to an ear WITHOUT a competing sound present to the opposite ear

Question 19

When a situation calls for masking what does it mean?

Answer 19

A competing sound is being presented to the opposite ear to increase the threshold in the ear we’re testing

Question 20

For Bone Conduction, what does unmasked always provide?

Answer 20

An unmasked bone will ALWAYS provide a response for the BETTER hearing ear
