27
Q

NU6 is made up of …

A

a consonant, nucleus, consonant

harder vocab

28
Q

Performance Intensity level:

A
  • useful in diagnosing retrocochlear dysfunction (VIII nerve)
  • Time consuming but faster than a ABR/MRI
  • identify point of roll over
29
Q

For performance intensity level, % correct will ______ and _________ normal listeners and sensorineural (cochlear) hearing loss.

A

peak and maintain

30
Q

Or, % correct will ____ and ______ with higher intensities for retrocochlear disease.

A

peak and then decrease

31
Q

What is the point of “roll over”?

A
  • PB max -(PB min / PB max)

0. 25-0.45=-0.2 significant difference

32
Q

Categories of performance:

A
  • pg 137
  • often used in reports
  • relevance depends on testing materials
  • Booth effect
33
Q

What is the Booth effect?

A

-when you place a patient in a sound treated room with no distractions they will be focused on testing

34
Q

Presentation Levels:

Sensation Level

A
  • typical 35-40 dB above SRT
  • provides discrimination accuracy at sufficient volume above threshold
  • may be inadequate depending on hearing loss configuration
35
Q

Presentation levels:

Conversational Level

A
  • helpful in looking at real world communication skills

- May help person see need for hearing aids

36
Q

Masking noise choices:

A
  • speech babble
  • multi-talker babble
  • speech weighted noise (spectrum)
  • running discourse
  • white noise
37
Q

Masking formulas

A
  • SRT te - IA greater than or equal to nte
  • If no BC data, assume 0 dBHL
  • If no SL is greater or equal to 40 dBHL, mask
38
Q

Dynamic Range

MCL

A
  • most comfortable listening level
  • patients subjective opinion
  • can be done with pure tones
  • primarily used for speech testing
39
Q

Dynamic Range

LDL (UCL)

A
  • Patients subjective opinion of uncomfortable level

- pure tones, but primarily speech

40
Q

Dynamic Range

SRT LDL

A
  • Dynamic range of hearing (threshold to discomfort)

- Reduced dynamic range in problematic

41
Q

Recruitment

A

-Unusual growth in loudness perception
-Perception changes quickly with limited increase in dB
MCL may be only slightly above the SRT
Low % scores due to insufficient gain
-Creates a small dynamic range
Tend to do poorly with hearing aids
May not tolerate increased input levels

  • Body parts
  • Same/different
  • SERT sound effects recognition test
56
Q

Ling Six sound test:

A
  • each sound is representative of a frequency range
  • help determine threshold levels
  • check aided function
  • reception/perception
57
Q
