Q

Why do we test a listener’s ability to perceive speech?

A
  1. Communication is essential to living
  2. High face validity (repeatable/standardized)
  3. Rehabilitation
  4. Cross check for pure-tone measures
  5. Differential diagnosis

Q

Outcome of SDT/SAT?

A

provides a threshold measure for speech detection

17
Q

The threshold for SDT/SAT should be within _____ of the best threshold.

A

5 dB

18
Q

to determine how well a patient perceived speech at levels experienced in day-to-day communication

A

Speech Recognition Tests in Quiet

19
Q

Stimuli of Speech Recognition Tests in Quiet?

A

Monosyllabic Words or Sentences

20
Q

Procedure of Speech Recognition Tests in Quiet?

A
  1. Instructions
  2. Presentation
  3. Evaluation
21
Q

Outcome of Speech Recognition Tests in Quiet?

A

sensitive to pathologies that disrupt the integrity of the acoustic signal, but have little impact on pure-tone thresholds
insensitive to performance differences for listeners with or without hearing loss and differing degrees and configurations of hearing loss

22
Q

Speech Recognition Tests in Quiet is typically given at ___-___ dB above the SRT.

A

30-40 dB

23
Q

Describing Performance

A 
Excellent: 90-100%
Good/Slight difficulty: 78-88%
Fair/Moderate: 66-76%
Poor/Great: 54-64%
Very poor: <52%
24
Q

to determine how well a patient understands speech in typical communication environments

A

Speech Recognition in Noisee

25
Q

Stimuli for Speech Recognition in Noise

A

Monosyllabic Words or Sentences in speech-shaped noise, broadband noise, or multitalker babble

26
Q

Procedure for Speech Recognition in Noise

A
  1. Instructions
  2. Presentation
  3. Evaluation
27
Q

Outcome for Speech Recognition in Noise

A

Scores are reported in % correct
the performance of patients with hearing loss is poorer than that of listeners with normal hearing (they require a higher signal-to-noise ratio to do as well

28
Q

level of the signal relative to the level of noise

A

Signal-to-noise Ratio

29
Q

Formula to find the Signal-to-noise Ratio

A

SNR = Signal (in dB HL) - Noise (in db HL)

30
Q

Test Presentation Levels (2):

A

Most Comfortable Loudness (MCL)

Performance intensity functions (several levels above threshold)

31
Q

Rollover

A

the louder the sound gets the poorer the performance; occurs in people with 8th nerve tumors
