Measuring the Effect of a Hearing Aid

---

1.  What is required for a patient to use amplification on a daily basis? Hearing aids a reliable The patient is motivated The patient perceives benefit All of the above

2.  In the opinion of the instructor, what primary condition(s) must be met for a fitting to be considered successful? The fitting must meet the HCP’s audiological criteria The fitting must provide the patient with perceived benefit/value The fitting must match prescribed fitting targets The devices must be worn at least 10 hours per day on average

3.  Matching real-ear targets provides: Reasonable assurance that speech in quiet will be audible Reasonable assurance that speech understanding in noise will approach normal Reasonable assurance that sound scene organization is possible Reasonable assurance that tonal balance and other sound quality dimensions are managed effectively for the patient

4.  What is the likely order of dimensions that a first-time user can reasonably provide valid feedback on after a new fitting, according to the instructor? Performance in noise, sound quality, tolerance Tolerance, sound quality, long-term outlook Tolerance, sound quality, performance in real world conditions Sound quality, sound booth performance, long-term outlook

5.  Typical clinical sound booth tests of speech understanding in noise: Usually do not include true spatial arrangement of sounds Usually do not include a variety of different competitions Usually do not include a range of talkers All of the above

6.  The value of standardized measures of speech understanding performance include: Clinical insight into a patient’s core ability to handle noise Repeatability Ability to compare performance with and without amplification All of the above

7.  When using standardized speech in noise measures: Testing should be performed at moderate input levels Testing level and speaker arrangement should be chosen to reflect the purpose of the testing, for example in order to evaluate the effects of advanced signal processing routines Testing should always be performed with the talker in front and the competition noise from behind Testing should always be performed with the talker and the noise from the same speaker

8.  Testing speech understanding under divided attention or dual-task conditions Is not allowed based on AAA guidelines Invalidates the task as the listener can be easily distracted Can provide a deeper level of insight into the communication challenges faced by the patient Becomes easier for patient as they get older

9.  The Arizona State University study discussed in the seminar indicated: The importance of simplifying the listening task to reveal processing differences The effect of adverse environmental conditions (heat & sun) on the ability to test speech in noise That children cannot be tested using complex testing paradigms That complex cognitive tasks can reveal differences between signal processing systems that my not show up using simpler testing approaches

10.  Physiological testing has revealed: Listening effort or fatigue can be monitored in different ways Listeners can track more than one talker at a time The addition of advanced signal processing can reduce listening effort All of the above
