Audiology Praxis Study Questions
with Correct Answers
What features of an assessment will affect reliability - Answer-test-retest, inter-tester
and inter-rater reliability.
Classroom noise acceptable noise level - Answer-35dBA and less or equal to .6
seconds reverberation time
OSHA how much sound for 8 hours - Answer-85dB: then it goes down by half time for
every 5 dB increase
NIOSH is ____ stringent than OSHA - Answer-more
Workplace portable eqiupment - Answer-portable audiometer, tymps and OAES, Sound
level meter
Screening levels for kids vs adults - Answer-20dB for kids vs 30dB for adults
standard threshold shift - Answer-10dB down from baseline in either ear from the
puretone average of 2k, 3k and 4k.
Time weighted average - Answer-time you're able to be exposed to a certain amount of
noise
Person failed a screening, then what - Answer-screen again, make sure they are noise
free for 14 hours, see if an age directive needs to be applied in case it's presbycusis.
JIH screening guidelines - Answer-1, 3, 6 : screen, diagnose, treat
Headphone options - Answer-TDH headphones (on the ear): some high frequencies
might slip out, good for people with medical stuff (40dB IAA)
Over the ear headphones: high frequency audiometry
inserts: better for high frequencies but easier to collapse ear canals, also you don't have
mask as much (60dB)
Why is the warble tone used in the sound field - Answer-so standing waves aren't
created
WRS presented at - Answer-30 above SRT or 5 below LDL/UCL
jerger type A - Answer-normal
, jerger type B - Answer-flat
jerger type C - Answer-negative
jerger type D - Answer-high admittance
reflex decay indications? - Answer-neuroma, schwannoma
Subjective questionnaires - Answer-APHAB, COSI, HHIE, COAT
Rotational testing - Answer-no ear specific information, looks at the whole body.
Indicated when you have an inconclusive VNG.
Cold water is used in VNG/ENG to - Answer-inhibit the auditory system. Shocks the
system if you can't get a response with cool or warm
Gaze - Answer-look different directions
saccade parameters - Answer-accuracy, latency, peak velocity [random dots and
movements]
Acoustic parameters - Answer-amplitude, frequency, phase, wavelength
frequency is the inverse of - Answer-period
period = - Answer-1/f
libbyhorn - Answer-used to increase high frequency response
longer the libbyhorn - Answer-the more high frequency boost
precedence effect - Answer-if a sound is coming from two directions and arrives at the
same time, you will localize whichever sound is louder
ILD - Answer-interaural level difference
vowels carry ____ energy than consonants - Answer-more
At what frequencies and intensities are most speech sounds produced? - Answer-
Around 40-50dB and between 250 and 500.
What is the relationship between SPL and HL? - Answer-The difference is biggest in the
low and high frequencies, and smallest in the mid frequencies. HL has been normed on
lots of normal hearing people to create a more visually appealing scale.
