GSI Corti: New Features to Enhance Workflow

---

1.  When interpreting DPOAE test results, it is important to consider the following: Presence or absence of DPOAE Overall Noise Floor Signal to Noise Ratio All of the above

2.  A DPOAE that is 6dB above the noise floor ______ indicates normal OHC function. Always Never Sometimes None of the above

3.  To access sub-menus on the GSI Corti, from the time and date screen: Press the right arrow button. Press and hold the down button for 3 seconds or until the green "READY" light turns off.- Press the left arrow button. All of the above

4.  Using GSI Auto Print, automatic printing of all Corti OAE test results will occur: As soon as the Corti is connected to the PC As soon as the Corti is placed in the cradle that is connected to the PC Both a and b B only

5.  The following statement(s) are true regarding the published normative OAE data collected at Boys Town: DPOAE test data was collected in over 1200 ears Subject ages in this study ranged from 1 to 96 years Subjects with varying degrees of hearing as determined by pure tone audiometry were included. All of the above

6.  With GSI Auto Print, it is possible to print OAE data using: PDF, any connected PC printer OR a PC based label printer Small mini-printer only Both a and b None of the above

7.  The benefits of viewing normative data on the GSI Corti are: Can be used as a guide when interpreting DPOAE test results Provides instant interpretation assistance before results are imported to the Data Manager Provides normative data for TEOAE protocols Both a and b

8.  The following advanced options can be modified on the GSI Corti: Test frequencies Averaging Time per Frequency L1/L2 ratio None of the above

9.  For screening protocols, it is possible to enable an additional requirement for minimum OAE amplitude in addition to the number of frequencies to pass. The minimum amplitude for DPOAE protocols is: -5 dB -10 dB -15 dB -20 dB

10.  DPOAE test results that fall above the normative data shaded area: Have a high probability of coming from a normal hearing ear. Have a high probability of coming from a hearing impaired ear Both a and b None of the above
