Audiology Exam #2 UPDATED ACTUAL
Exam Questions and CORRECT Answers
The primary way by which cross-hearing for air conduction takes place is by - CORRECT
ANSWER - bone conduction.
Overmasking is the greatest problem in - CORRECT ANSWER - bilateral conductive loss.
The most efficient kind of masking noise for pure-tone testing is - CORRECT ANSWER -
narrowband noise.
The masking plateau becomes narrower as the - CORRECT ANSWER - BC threshold in
the test ear gets lower (better)
The energy lost as sound travels from one ear to the other is called - CORRECT
ANSWER - interaural attenuation
Unmasked results on a patient with one normal ear and one ear with a total sensorineural loss
show the poorer ear to have - CORRECT ANSWER - moderate conductive hearing loss
PB MAX - PB MIN/PB MAX is the formula for - CORRECT ANSWER - rollover ratio
SRT's are usually measured with - CORRECT ANSWER - spondaic words
RCL (DR) is determined by the difference (in decibels) between - CORRECT ANSWER -
UCL and SRT
The relationship between SRT and SDT is usually - CORRECT ANSWER - SRT 10 dB
higher (poorer) than SDT
,The slope of the normal PI-PB function averages ___ percent per dB - CORRECT
ANSWER - 2.5
The word-recognition score expected of a patient with moderate conductive hearing loss is ___
percent. - CORRECT ANSWER - 100
The last word of the carrier phrase in word-recognition testing with PB word lists should -
CORRECT ANSWER - strike 0 on the volume units (VU) meter
The PI function for spondees is usually - CORRECT ANSWER - steeper than for PB's
The word-recognition score expected of a patient with a mild cochlear hearing loss is ____
percent. - CORRECT ANSWER - 80
In audiograms showing sharply falling (in the higher frequencies) sensornieural hearing loss, the
SRT is best predicted by the average of the thresholds at _____ Hz. - CORRECT
ANSWER - 500 and 1000
Word-recognition scores are most commonly determined by using - CORRECT
ANSWER - PB word lists
Audibility Index or Articulation Index (AI) - CORRECT ANSWER - count the dot
audiogram, Can be helpful for SLPs in therapy, can also use the Audiogram of Familiar Sounds
LDL or UCL - CORRECT ANSWER - Loudness Discomfort Level or Uncomfortable
Loudness Level
MCL - CORRECT ANSWER - Most Comfortable Loudness
PB Max is the highest score - CORRECT ANSWER - an individual person can obtain on a
specific test
, Maximum score on speech discrimination tests is usually about - CORRECT ANSWER -
40dB above the SRT provided it is also above the pure tone threshold at 2000 Hz. This varies by
person and degree/configuration of hearing loss
Higher SNR is better for - CORRECT ANSWER - hearing/understanding speech
Signal to Noise Ratio (SNR): - CORRECT ANSWER - difference in intensity between the
signal (speech you want to hear) and the noise (speech or background that you don't want to
hear)
Sentences in Speech Testing can be - CORRECT ANSWER - synthetic or connected
speech
Pure Tone, SRT & Speech in Quiet are all apart of - CORRECT ANSWER - Basic
Hearing Test
Different word list are important for Speech Testing because - CORRECT ANSWER -
they need to be appropriate for the population, children vs adults
Speech Discrimination/Recognition or Word Recognition Scores (SDS/SRS/WRS) require -
CORRECT ANSWER - Speech in Quiet
One syllable words
25 vs 50 word lists (half vs. whole) (**Thorton and Raffin)
Phonetically Balanced (PB)-W22
CNC-consonant-nucleus consonant
NU6
Children vs Adult word lists
Speech Discrimination/Recognition or Word Recognition Scores (SDS/SRS/WRS) is also know
as - CORRECT ANSWER - 'Discrim'
