Term
| What kind of hearing loss is the Stenger Test designed for? |
|
Definition
|
|
Term
| The Stenger Test is based on the Stenger principle which is when two tones/stimuli (spondee word) of the same ___ are introduced at the same time into both ears; only the ___ stimulus will be perceived |
|
Definition

Term
Stenger Test - Method:
-Present stimuli to ___ ___ at same time
-ask pt to ___ word when hears stimuli
-Initially, present to ___ ear at a comfortable, audible level (e.g. 20 dB SL) & to “poorer” ear at ___ dB below the level of the good ear. Pt will respond because hears sound in ___ ear
-Then increase intensity level of signal in “___” ear. Pt stops responding when hears sound in “___” ear |

Term
Stenger Test - Interpretation:
-Negative Stenger suggests ___ hearing loss. Pt keeps responding to signal being presented to ___ ear
-Positive Stenger suggests ___ loss
-Pt stops responding when signal loudness in “poorer” ear ___ loudness in good ear
-Due to Stenger principle, only the signal in the “___” ear will be heard |

The Lombard Effect:
-Principle: listeners monitor level of their own ___ through their auditory system
-Lombard effect: pt’s increase voice level when ___ ___ is present
-The Lombard Test: Ask listener to read a passage as you gradually increase the level of ___ in their ears
-If masker levels are REALLY below their hearing levels, they will ___ raise voice level |

|
Term
| What are some behaviors that suggest malingering? |
|
Definition
-Exaggerated listening behaviors
-Vague or no responses to pt interview
-May respond appropriately to avg or soft conversation then volunteer responses in the test booth that do not agree with this observation
-Many false negative responses & few false positive responses |
|
|
Term
Results That are Red Flags:
-No ___ ___ (in asymmetric/unilateral). Get unmasked thresholds before introducing ___
-poor reliability for ascending vs. descending presentations. Use ___ presentations so that listener has no reference level for loudness
-inconsistent ___ responses. >___ dB difference in levels volunteered as “thresholds” |

Speech Findings:
-___ responses to SRT testing
-Reporting “___________” for spondees. This level may represent the ____
-Poor agreement (>8 dB) between ___ & ___ responses to pure-tones. Speech perceived as ___ than tones due to wider bandwidth for speech
-PI-PB function: excellent scores at ___ presentation levels |

Term
| What are some tests for non-organic loss? |
|
Definition
| OAEs, immittance measures, ABR, stenger test, and lombard effect |
|
|
Term
Otoacoustic Emissions:
-not typically present in ears with > ___-___ dB loss
-if present; suggests no more than ___ loss (or normal
hearing sensitivity)
-Disadvantages: Can not ___ loss and absence of OAEs may not yield ___ |
|
Definition
| 30-40; mild; quantify; information |
|
|
Term
Acoustic Reflex Thresholds:
-audiogram thresholds can NOT be ___ than ARTs
-for normal to 60 dB HL thresholds, expect to elicit ARTs at essentially the same ___. Implication: ARTs not helpful if pt is ___ mild/moderate loss
-SPAR: ___ prediction by acoustic reflexes. ___ ARTs elicited by tones & BBN |

Term
Auditory Evoked Potentials:
-Use ABR when cannot obtain ___ thresholds
-Does not require pt to ___
-Can predict hearing sensitivity at different ___
-can predict hearing sensitivity at 2000-4000 Hz region
within __-__ dB
-may use 500 Hz tone burst to predict LF hearing
-Disadvantages: Time consuming, more expensive, may not obtain as much freq-specific information as would for pure-tone testing |

Term
| Level at which there is 0% compensable loss present. Hearing loss < 25 dB HL is not compensable |
|
Definition
|
|
Term
___ ___: level (92 dB HL) at which a 100%. compensable loss exits
-Thresholds between low & high fence correspond to impairments ranging from 0 to 100%.
-Each decibel of loss above 25 dB HL contributes ___% toward the percentage of hearing impairment. |
