Baby DPOAEs: Not Just Smaller Adults!, presented in partnership with Cincinnati Children's

---

1.  What are the most predictive frequencies for interpretation of DPOAEs in infants? 1 - 8 kHz 3 - 8 kHz 2 - 4 kHz 0.5 - 2 kHz

2.  Increasing the number of frequencies required to pass in a multi-frequency analysis will have the following effect: Increase sensitivity, increase specificity Increase sensitivity, decrease specificity Decrease sensitivity, increase specificity Decrease sensitivity, decrease specificity

3.  Infant DPOAE responses are larger than adults primarily due to: Supernumerary hair cells at birth Immaturities of the ear canal size and middle ear mechanics Immaturities of the MOO system and its regulatory effect on cochlear function Decreased exposure to environmental factors such as noise and ototoxins

4.  Compared to normal hearing infants, DPOAEs in infants with hearing loss display: Reduced DPOAE signal levels and smaller SNRs Reduced DPOAE signal levels with no change in SNR Increased DPOAE signal levels with small SNRs Increased DPOAE signal levels with no change in SNRs

5.  Differences in noise levels between infants and adults can be attributed which of the following factors: Infants tend to breathe more rapidly and noisily than adults The ear canal wall is less compliant The infant ear canal is shorter and the tympanic membrane has a more horizontal orientation It can be harder to maintain a good probe seal

6.  In order to correctly interpret type of hearing loss, DPOAEs can be: Combined with wideband absorbance testing Combined with TEOAE testing Combined with acoustic reflex testing Combined with air conduction ABR

7.  In the presence of normal middle ear function, if DPOAE signal and SNR is low, what is the correct interpretation? Conductive hearing loss is more likely Sensorineural hearing loss is more likely The DPOAE is uninterpretable Mixed hearing loss is more likely

8.  If DPOAE signal is normal, but SNR is low, what is the correct interpretation? Conductive hearing loss is more likely Sensorineural hearing loss is more likely The DPOAE is uninterpretable Mixed hearing loss is more likely

9.  If DPOAE signal is normal but wideband absorbance is low, what is the correct interpretation? Minimal conductive loss is more likely Sensorineural hearing loss is more likely Hearing loss is likely no greater than 50 dB Mixed hearing loss is more likely

10.  If DPOAE signal is normal and wideband absorbance is normal, what is the correct interpretation? Minimal conductive loss is more likely Sensorineural hearing loss is more likely Hearing level is likely no greater than 30 dB Mixed hearing loss is more likely
