20Q: Word Recognition Testing – Let’s Just Agree to do it Right!

---

1.  The primary purpose of conducting word recognition is to: Predict the patient’s speech-in-noise score Predict how the person will understand speech in the real world Determine how well a patient will understand average-level speech Determine the person’s optimum speech understanding under ideal conditions

2.  A major limitation of using the “SRT+40” dB approach for speech recognition testing with downward sloping hearing losses is: Important high-frequency speech sounds may not be audible This level will often exceed the patient’s LDL This level might not be patient’s MCL This level doesn’t represent real-world speech

3.  Guthrie and Mackerzie (2009) found that the best level for finding PB-Max was: SRT + 40 dB PTA + 40 dB LDL - 5 dB MCL

4.  Which of the following statements is true about the “2K Threshold + SL” approach? It requires you to do an extra test (the speech LDL) 2K thresholds are more reliable than speech LDLs It should not be used as it will overestimate true performance It should not be used as it will underestimate true performance

5.  The major problem of using only ½ of an NU-6 list to derive a word recognition score: The words are not balanced for familiarity The words are not balanced for difficulty The words are not balanced phonetically Queuing up the recording takes valuable test time

6.  Research has shown, that for the NU-6 list, on average, we’d expect the difference between the first and second ½ of this word list to be about: 4% 8% 12% 16%

7.  Using the Hurley and Sells 10-Word screening, you can stop your testing if: The patient only misses one word The patient only misses two words The patient only misses three words The patient only misses four words

8.  The Hurley and Sells method starts word recognition testing with which words? Most difficult Easiest Shortest Longest

9.  Using the Thornton and Raffin data (50 words), if the first test score is 70%, which of the following scores would be considered significantly different? 60% 70% 54% 88%

10.  When is it recommended to use monitored live voice stimuli for word recognition? When the audiologist has more than 5 years of experience When the audiologist is in a hurry When you don't have recorded materials handy at a test location Never - it has poor reliability, poor validity, and is not best practices
