Common Errors in Measurement and Analysis of OAEs

---

1.  Which one of the following procedures should be routinely done before OAE measurement (except for newborn hearing screening with OAEs)? Air conduction pure tone audiometry Bone conduction pure tone audiometry Tympanometry Otoscopy

2.  Which one of the following steps should be taken at the beginning of OAE recording? Air conduction pure tone audiometry Bone conduction pure tone audiometry Tympanometry Verification of stimulus intensity levels

3.  Which one of the following steps should be taken periodically throughout OAE recording? Patient instruction Manipulation of stimulus intensity levels Monitoring noise levels Middle ear measurement

4.  Which one of the following steps is a good policy in clinical measurement of DPOAEs? Replication of (repeating) DP recordings for each ear Otoscopy after completion of each DPgram Tympanometry after completion of each DPgram Reinsertion of the probe tip after completion of each DPgram

5.  Which one of the following is a reasonable number of test frequencies per octave for a diagnostic OAE recording? 1 2 3 ≥5

6.  The presence of OAEs at any test frequency is typically indicated by an OAE noise floor difference of? 1-3 dB 3-5 dB ≥6 ≥20

7.  Normal OAEs at any test frequency is typically indicated by? An OAE – noise recording difference of ≥6 dB An OAE – noise recording difference of ≥10 dB A noise recording – OAE difference of ≥6 dB OAE amplitudes within a normal region and OAE – noise difference of ≥6 dB

8.  To reduce the noise floor during OAE recording: Move the patient closer to the OAE equipment Use a shallow probe tube insertion Use a smaller (looser) probe Use a tight probe fit, deep probe insertion, and minimize ambient noise

9.  Which problem must be ruled out if OAEs are absent at all test frequencies? Middle ear dysfunction Inner hair cell dysfunction ANSD APD

10.  A finding of normal OAEs at all test frequencies is most consistent with? Hearing sensitivity levels < 15 dB HL Outer hair cell dysfunction A mild-to-moderate sensory hearing loss Eustachian tube dysfunction
