Don’t Miss the Point! The Importance of Detecting Hidden Audiogram Notches

---

1.  The ASHA Guidelines for Manual Pure-Tone Threshold Audiometry recommends which air conduction frequencies be tested during all adult audiologic evaluations? 250, 500, 1000, 2000, 4000, and 8000 Hz 250, 500, 1000, 1500, 2000, 3000, 4000, 6000 and 8000 Hz 250, 500, 1000, 2000, 3000, 4000, 6000 and 8000 Hz 250, 500, 1000, 2000, 4000, 6000 and 8000 Hz

2.  What percentage of veterans in Wilson and McArdle (2013) were identified with notches? 13% 24% 10% 75%

3.  An audiogram shows thresholds at 2000 Hz and 4000 Hz are 5 dB and 15dB respectively. Which of the following would be considered a notch at 3000 Hz under the Wilson (2011) definition? 10 dB 15 dB 20 dB 25 dB

4.  What relation between age and prevalence of notches in their study did Wilson and McArdle (2013) find? Prevalence of notches increases with age Prevalence of notches decreases with age There was an even distribution of the prevalence of notches with age There was no finding presented

5.  Presence of an audiometric notch in the speech frequencies should be noted in the following clinical evaluations: ototoxic monitoring verification of hearing aid settings tinnitus assessments all of the above
