Hearing Aids Dispenser II - Final Exam Correctly Answers

Hearing Aids Dispenser II - Final Exam Correctly Answers List five *assessment and verification* measures. - CORRECT ANSWER-1) The aided audiogram 2) Speech testing 3) Real ear measurement 4) Subjective measures 5) Surveys/Communication scales What do our textbook authors say about the usefulness of aided audiograms? - CORRECT ANSWER-Aided audiograms are *rarely useful*. But Peterson disagrees because certain professionals love them. Which professionals tend to love aided audiograms? - CORRECT ANSWER-Teachers of the hearing impaired and SLPs. Because they are simple, straightforward, and they know how to read an audiogram - they tend to have more trouble understanding probe mic verification. Are you getting precise verification with aided audiograms? - CORRECT ANSWER-No. They have some face validity for when you are communicating with other professionals, but they are not very precise. When is *aided vs. unaided speech testing* (at normal conversational levels) useful as a verification measure? - CORRECT ANSWER-Aided vs. unaided speech testing, at normal conversational levels, is *useful for specific patients*. One such use would be to demonstrate to patients or their families that the aids are actually helping. Ex: Peterson's example of the woman who convinced her granddaughter that the aids didn't do anything, but had significantly better word recognition when the aids were on. When is *real ear measurement* useful? - CORRECT ANSWER-Real-ear measurement is *useful for all patients*. When are *subjective measurements* useful? - CORRECT ANSWER-Subjective measurements are *useful for specific patients.* When are *surveys/communication scales* useful? - CORRECT ANSWERSurveys/communication scales are *useful for most patients*. What did a recent study determine regarding the benefit of conducting surveys? - CORRECT ANSWER-The study found that *regardless of what questions you ask*, simply *sending out a survey increased satisfaction by 15-20%.* What was the aided audiogram called historically? - CORRECT ANSWER-Functional gain measure How do you obtain an aided audiogram? - CORRECT ANSWER---Patient goes into the sound booth, *puts the hearing aids on* and sits *one meter from the speaker* --Patient raises his/her hand in response to *warble tones* and you get an aided threshold (A) --Can compare the aided threshold to ear-specific thresholds or do an unaided soundfield test for a true comparison (so it would compare S vs. A) If a patient's aided soundfield threshold (A) was 30 dB better than their unaided soundfield threshold (S) at 1000 Hz, how would you describe that improvement? - CORRECT ANSWER-They have 30 dB *functional gain* at 1000 Hz. What are four reasons why the aided audiogram rarely useful? - CORRECT ANSWER1) Fewer data points because we have *only FIVE measurement points for frequency* (while probe mic has maybe 1005) 2) *Uses 5 dB increments* so it is *LESS PRECISE in terms of intensity* 3) *Tells us NOTHING about CONVERSATIONAL SPEECH and LOUD inputs* - only gives us data about the *maximum gain benefit* at *soft inputs* because it is a *threshold* test - creates a false sense of gain amount 4) *Test is SUBJECTIVE* because we rely on a behavioral response Summarize the limitations of the aided audiogram. - CORRECT ANSWER-1) Restricted data points in terms of *FREQUENCY* (because only 5 frequencies measured) 2) Restricted data points in terms of *INTENSITY* (because 5 dB increments) 3) Only measures *gain for SOFT inputs* 4) Uses a *SUBJECTIVE response* Summarize the five *assessment and verification measures* and the *usefulness* of each. - CORRECT ANSWER-1) Aided audiogram - Rarely useful 2) Speech testing - Useful for specific patients 3) Real ear measure
