OAEs that are recorded with two tonal stimuli are called:

Describe in detail a concept covered in class or in the readings since the midterm that was not on this exam. Up to 3 points.

Little Timmy has otitis media in his left ear, which causes a hearing loss in that ear. His air conduction thresholds indicate a mild to moderate loss while his bone conduction scores are in the normal range. The minimum air-bone gaps are 15 dB HL. What type of hearing does littte Timmy have?

Case 1 The patient is a 54 year old male with complaints of fullness in his left ear and difficulty hearing in background noise. He denies significant otologic history and has no major medical history. Using the following test results, indicate where masking is necessary and the Mmax for each area. Remember to look at pure tones and speech. Assume no thresholds or responses changed with masking. final case 1.jpg final oaes case1.jpg 

How much must be added when calculating a starting level for plateau masking for an air-conducted 500 Hz signal?

Case 2. Patient is a 3-year-old female who has had a history of ear infections that were treated with antibiotics. Mom has concerns because the patient has a very small vocabulary compared to her other children. The patient did not respond to speech stimuli, but frequency- and ear-specific testing was able to be completed under headphones. Otoscopy was not tolerated. Using the test results below, write the “O” and “A” sections of a report. case 2.jpg

You are presenting masking at AC thresholds plus interaural attenuation minus 5 dB. Which technique is this?

What testing technique would have been most appropriate for this patient? Why? What are the procedures/steps for the chosen technique?

Using the data from Case 1, write the results for the OAEs as you would in the “A” section of the report.

The audiogram below was obtained using supra-aural headphones. The audiologist is testing word recognition next and plans to present at 65 dB HL in both ears. Is masking required? If so, for which ear/s? audiogram – 2024-07-23T132624.914.png
