Olsen & Noffsinger Tone Decay Test (1974):

-Maintains good ___ (95% hit rate)
-Ask pt to raise finger when they ___ tone (keep finger ___ for as long as ___ tone, put finger down when no longer hear tone)
-Start presenting at __ dB SL, increase in __ dB steps until pt responds
-Start timing when pt ___
-Stop test if pt responds a full __ sec
-If signal fades & pt stops responding (before 60 sec is up),
increase by __ dB without interruption & ___ timing
-Continue until pt hears tone ___ minute or signal reaches ___ dB SL |

|
Definition
| Alternate Binaurall Loudness Balance |

Term
ABLB:
-Method: compares ___ ___ in an impaired ear versus a normal ear
-Underpinning: based on discovery of ___ loudness growth in cochlear pathology |
|
Definition
| loudness growth; abnormal |
|

Term
ABLB – General Principles:
-a test of recruitment for ___ loss
-compare loudness growth for same ___ between both ears
-Need less intensity in the ___ ear vs.normal ear to result in judgment of “equal loudness” |

ABLB – Test Administration:
-alternate presentation of a fixed freq tone between ___
-keep intensity constant in ___ ear; vary intensity in ___ ear
-the good ear is the “___ ear”; ask pt to report if tone is
“___ than”, “___ than”, or “___ to” tone in the good ear
-Start in the good ear at ___ dB SL; alter intensity in impaired ear until patient judges tones to be ___ loud
-after pt judges equal loudness, increase intensity in ___ dB steps in ___ ear (then vary tone in bad ear until judged to be equally loud)…until pt’s ___ ___ ___ is reached (or you reach limits of audiometer) |

ABLB: Results & Interpretation:
-Complete recruitment: When equal loudness judgments are made at equal ___ (+/-10 dB). Suggests ___ disorder.
-No recruitment: When equal loudness judgments are made at equal ___ (+/-10 dB); results are ___.
-Partial recruitment: When equal loudness judgments fall between ___ & no ___
-Decruitment: When poor ear needs an ever ___ intensity to equal loudness of tone in good ear . Suggests ___ disorder; loudness in bad ear grows more ___ than in normal ear |
