Part 2.2

Question 1

Sensation level refers to:

a) The level at which an individual can just detect sound
b) The average hearing curve
c) Hearing threshold re: 0.0002 dynes/cm2
d) The threshold value above average normal hearing
e) A sound presented relative to the individual’s threshold

Answer 1

e) A sound presented relative to the individual’s threshold

Remember, sensation is subjective.

Question 2

Localization in binaural hearing depends on:

a) Loudness squelch
b) Signal strength reaching the two ears
c) Loudness summation
d) Arrival time of signal at the two ears
e) b and d

Answer 2

e) b and d

Localization in binaural means you are locating the source of a sound and you’ve got two ears. Strength and time can help triangulate the signal.

Question 3

The reduction of the intensity of the sound as it passes from one side of the head to the other is:

a) Masking
b) Loudness squelch
c) Interaural attenuation
d) Venting
e) Summation effect

Answer 3

c) Interaural attenuation

Question 4

The major parts of the peripheral hearing system include the…

a) Outer ear
b) Middle ear
c) Inner ear
d) Brainstem
e) a, b, and c

Answer 4

e) a, b, and c

The brainstem is too far inside the skull to be considered peripheral.

Question 5

A similar term for balance system is…

a) Retrocochlear
b) Ossicular chain
c) Vestibular system
d) Horizontal, lateral, and utrical canals

Answer 5

c) Vestibular system

You should be breaking the parts of the words down, understanding the Latin involved,
that will help you greatly.

Question 6

The human ear can respond to approximately what frequency range?

a) 500 - 3000 Hz
b) 1 - 24000 Hz
c) 25 - 25000 Hz
d) 20 - 20000 Hz

Answer 6

d) 20 - 20000 Hz

Question 7

The type of hearing loss usually associated with presbycusis is…

a) Conductive
b) Mixed
c) Sensorineural
d) Psychogenic

Answer 7

c) Sensorineural

Question 8

The usual technique for pure tone testing is…

a) Ascending
b) Descending
c) Off-on-off tone
d) Ascending/descending

Answer 8

d) Ascending/descending

Question 9

It is standard procedure to begin testing at…

a) 2000 Hz
b) 1500 Hz
c) 1000 Hz
d) 500 Hz

Answer 9

c) 1000 Hz

Question 10

The type of word used in establishing SRT is…

a) Phonetically balanced
b) Spondaic
c) Synonymic
d) Anatomical

Answer 10

b) Spondaic

Question 11

An advantage of digital hearing aids is…

a) Ability to differentiate background noise
b) Ability to differentiate between speech and noise
c) Ability to increase signal to noise ratio
d) Longer battery life

Answer 11

b) Ability to differentiate between speech and noise

Don’t get complex.

Question 12

How many octaves are there between 250 and 8000Hz?

a) 2
b) 3
c) 3
d) 4
e) 5

Answer 12

e) 5

An octave doubles the Hz. Do the math.

Question 13

Another term for maximum output limitation of a hearing aid is what?

a) Maximum gain
b) Reference test gain
c) OSPL 90
d) Frequency response

Answer 13

c) OSPL 90

Gain is just part of the output. Frequency response doesn’t relate. Look up OSPL.

Question 14

The ‘normal’ intensity of a speaker’s voice at a distance of one meter is likely to be _____?

a) 65-70 dB SPL
b) 65-70 dB HTL
c) 45-50 dB SPL
d) 20 dB SPL

Answer 14

a) 65-70 dB SPL

Straight memorization.

Question 15

It is common procedure to begin testing _____?

a) The poorer ear first
b) Both ears together
c) The better ear first
d) In the ear the client uses the telephone with

Answer 15

c) The better ear first

If you begin with the poorer ear, the better ear might be helping. If you begin with the better
ear nothing is going to help it.
