ILE Subscription Test Prep/Class Test Prep Questions And Answers A+ What are 4 ways to correct the occlusion effect? - ANS-1. Reduce the LOWS 2. make the fitting more "open" like RIC styles or thin tube BTE's coupled to the ear with open domes. Custom styles like CICs and IICs offer fewer venting options due to small shell sizes. 3. Increase vent size 4. SAV, is always a safe bet because its always easier to reduce the vent size than increase it Occlussion effect can sometimes be described by the wearer as their voice sounding like an "echo" or "down in a barrel." This is due to their ear being closed off and an increased amplification due to bone conduction. Patient's work environment includes both noisy and quiet areas. This requires the patient to make constant adjustments to the hearing instruments volume controls. Which specific measurement will be most important to obtain during the patient's hearing evaluation? MCL or UCL? - ANS-UCL, because (pg. 115-118) of the constant adjusting. They're dynamic range needs to fit their work environment. 36 year old female restaurant worker with a family history of hearing loss reports that she is unable to hear as well as she did two years ago. Testing reveals a moderate conductive hearing loss. What is the likely cause of the patient's change in hearing? Meniere's Disease or Otosclerosis - ANS-Otosclerosis pg. Pg. 43-46 disorders of the middle ear Otosclerosis is more common in women, and may be triggered by the hormonal changes of pregnancy. Otosclerosis is more of a progressive hearing loss. Meniere's Disease is classified as a SNHL. What is a Carhart's notch? - ANS-It's an audiometric feature that shows a dip at 2000 Hz when people likely have otosclerosis that results in stapedial fixation. Named for Dr. Raymond Carhart. Patient has moderate to severe SNHL bilaterally. Patient was fit with slim tube BTE instruments. During the initial follow-up, the hearing healthcare professional performed probe tube measurements, which fell below targets in the high frequency range. Patient's validation results reveal low satisfaction with the fitting. What fitting option should the hearing healthcare professional recommend? Change to mini-BTE's with open domes Change to RIC's with custom earmolds and medium vents - ANS-What are mini-BTE's? Change to mini-BTE's with open domes. This doesn't make sense because they already have BTE's and they aren't meeting high frequency range targets. Change to RIC's with custom earmolds and medium vents pg. 195-206. The medium vents may be able to increase high frequency sounds due to horn theory. What's horn theory? - ANS-An acoustic horn is a change in diameter of the sound channel from smaller to larger. This response increases the high frequencies. This theory is used for a Libby Horn/Horn Tube, or modified canal bore belled/hollowed on earmold for BTE fittings when programming adjustments for high frequency enhancement cause distortion and unnatural sound. Patient with digital BTE's with dual microphones reports difficulty hearing in noisy environments. Which parameter should the hearing healthcare professional adjust when reprogramming the HA's? Compression or Directionality - ANS-Directionality (pg. 171-182) because the noisy environments have noises coming from different directions, and they help with understanding speech in background noise. This makes the signal to noise ratio more favorable or the listener. Sound coming from the front will be louder than sound coming from the back. Compression doesn't make sense because it varies gain as the input changes. The compression kneepoint, or CK is when the intensity of amplification changes from linear to non-linear. Continues...
