Back to Basics: Pure Tone Testing and Audiogram Interpretation

Please note: exam questions are subject to change.

1. Many audiologists may test a mid-octave frequency during pure-tone testing when: The difference between two consecutive octave frequencies is 10 dB or more. The difference between two consecutive octave frequencies is 15 dB or more. The difference between two consecutive octave frequencies is 20 dB or more. The differences are disregarded and all frequencies, including mid-octaves, are tested in all cases.
2. When one sees this symbol written in blue on the audiogram ( ] ), it refers to: BC threshold for the right ear without masking BC threshold for the right ear with masking used BC threshold for the left ear without masking BC threshold for the left ear with masking used
3. You obtain AC thresholds in the right ear of 50 dB HL, 55 dB HL, 65 dB HL, and 70 dB HL at 250, 500, 1k and 2k Hz, respectively. What is your Pure-tone Average for that ear? 63 dB 65 dB 57 dB 60 dB
4. The pure-tone average, such as the one obtained in Question 3, should be in good agreement with which other audiologic assessment measure? PTA for the other ear SRT for the same ear WRS for the same ear Tympanogram for the same ear
5. When you see an audiogram that displays AC thresholds within the 60 – 65 dB HL range, what is the magnitude? Moderate Moderately-severe Severe Profound
6. Many audiologists consider a significant air-bone gap to be: A difference in AC and BC thresholds of> 10 dB at the same frequency, in the same ear Any difference in AC and BC thresholds at the same frequency, in the same ear A difference in AC and BC thresholds of>10 dB at the same frequency, in opposite ears A difference in AC and BC thresholds of> 20 dB at the same frequency, in the same ear
7. The major difference between a mixed hearing loss and a conductive hearing loss is: There are significant air-bone gaps with one and not with the other Otoscopic exam will be instrumental in helping to diagnose BC thresholds are within normal limits with a conductive loss, but not with a mixed loss Difference between these two types may not be ascertained by looking at the audiogram
8. Your audiometric configuration looks quite flat up to a certain frequency and then it is gradually falling. The best terminology or descriptor here would be: Rising Gradually sloping Cookie bite Trough-shaped
9. One of the biggest drawbacks when obtaining thresholds via sound field is: Calibration Individual ear information is not obtained Frequency specific information is not obtained Conditioning the patient is difficult
10. Performing an otoscopic examination prior to pure-tone testing is critical. This is to check for: Presence of cerumen Presence of collapsed canals Presence of visible disorders All of the above
