Answers |Actual Complete Update |Already Graded A+
What are the 2 BAER montages? State their laterality. ✔Correct Answer-1.) A1-Cz (LEFT)
2.) A2-Cz (RIGHT)
What are the LFF and HFF for BAERs? ✔Correct Answer-LFF: 10Hz-30Hz
RFF: 2500Hz-3000Hz
What is the BAER sensitivity? ✔Correct Answer-0.2uV/Div-0.5uV/Div
What is the analysis time for BAERs? ✔Correct Answer-15 milliseconds/Div
How many trials are in one run of BAERs? ✔Correct Answer-500-1000
What is the major ABR Frequency? ✔Correct Answer-1200Hz
What is the stimulus for BAERs? Both in dB HL and peSPL ✔Correct Answer-60-70dbHL =
100peSPL
What is masking in terms of BAERs? ✔Correct Answer-Masking is a noise that is implemented
to the contralateral auditory pathway that is utilized to make certain that we are only
monitoring the ipsilateral auditory pathway.
What frequency is masking imlemented at? ✔Correct Answer-30Hz-40Hz = 60peSPL
What are 3 common Rep Rates for BAERs? ✔Correct Answer-31.33Hz; 27.11Hz; 17.33Hz
Above what rep rate frequency quickly acquires Waves I and V but can possible degrade Wave
III? ✔Correct Answer->30Hz
Above what rep rate frequency degrades all BAER waveforms? ✔Correct Answer->50Hz
What are the clicks utilized to elicit BAERs? What are 2 major characteristics of these clicks?
✔Correct Answer-Broad Band Clicks
1.) 100uSec square wave pulses
2.) Large range of possible frequencies
What are the 3 BAER polarities? ✔Correct Answer-1.) Rarefaction
, 2.) Condensation
3.) Alternating
What are 4 characteristics of the Rarefaction BAER polarity? ✔Correct Answer-1.) Negative
pressure pulse
2.) Pulls tympanic membrane away from midline
3.) Short Latency
4.) Amplifies Wave I
What are 4 characteristics of the Condensation BAER polarity? ✔Correct Answer-1.) Positive
pressure pulse
2.) Pushes tympanic membrane toward midline
3.) Long latency
4.) Amplifies Wave V
What is the Alternative BAER polarity? What are 2 major advantages of utilizing this polarity?
✔Correct Answer-Goes back-and-forth between using condensation and rarefaction.
1.) Decreases stimulation artifact
2.) Eliminates cochlear microphonic
What is dBSPL? ✔Correct Answer-Sound Pressure Level - the lowest measurable sound
possible (considered to be 0Hz)
What is dB HL? Give an example. ✔Correct Answer-Hearing Level - the average hearing level
for a large group of people. Think the normal hearing range for all of the United States
What is dB nHL? Give an example. ✔Correct Answer-Normal Hearing Level - the hearing level
for a smaller, more specific group of people. Think the hearing range for all of the Seastnan
employees.
What is dB SL? Give an example ✔Correct Answer-Sensation Level - the hearing level of a
single individual. Think the hearing range for a patient.
What is peSPL? ✔Correct Answer-Peak Equivalent Sound Pressure Level - a comparison of the
peak-to-peak amplitude of the click stimulus with the amplitude of a pure tone sound
