above threshold
Suprathreshold
the presentation of standardized samples of speech through a calibration system in an attempt to examine a patient’s ability to perceive suprathreshold information
Speech Audiometry
Why do we test a listener’s ability to perceive speech?
- Communication is essential to living
- High face validity (repeatable/standardized)
- Rehabilitation
- Cross check for pure-tone measures
- Differential diagnosis
To determine the lowest level at which the patient can perceive (REPEAT) words with 50% accuracy
Speech Recognition (Reception) Threshold (SRT)
Stimuli of SRT test
Sponadic words
T/F Stimuli for SRT test may be presented via monitored live voice or using recorded materials
True
Procedure for SRT test
- Familiarization
- Presentation
- Adjustment
- Evaluation
Adjustment of stimuli Down 10, Up 5
The Modified Method of Limits
Outcome of SRT test:
Provides a threshold measure for speech production
Sponadic words
Two monosyllable words put together to make a third word (e.g., hot dog, ice cream, baseball)
The threshold for SRT should be within _______ of the _____ threshold
plus/minus five of the BEST threshold
To determine the lowest level that the patient can just detect the presence of speech 50% of the time
Speech Detection/Awareness Threshold (SDT/SAT)
When do you use SDT/SAT?
for very young children
handicapped adults/children
people who are monolingual
What are the stimuli for SDT/SAT?
Spondaic words
Procedure for SDT/SAT?
- Familiarization
- Presentation
- Adjustment
- Evaluation
Outcome of SDT/SAT?
provides a threshold measure for speech detection
The threshold for SDT/SAT should be within _____ of the best threshold.
5 dB
to determine how well a patient perceived speech at levels experienced in day-to-day communication
Speech Recognition Tests in Quiet
Stimuli of Speech Recognition Tests in Quiet?
Monosyllabic Words or Sentences
Procedure of Speech Recognition Tests in Quiet?
- Instructions
- Presentation
- Evaluation
Outcome of Speech Recognition Tests in Quiet?
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
Speech Recognition Tests in Quiet is typically given at ___-___ dB above the SRT.
30-40 dB
Describing Performance
Excellent: 90-100% Good/Slight difficulty: 78-88% Fair/Moderate: 66-76% Poor/Great: 54-64% Very poor: <52%
to determine how well a patient understands speech in typical communication environments
