Audiogram-Based Case Mock Questions (Using Diagram) Refer to the audiogram above to answer the following case-based questions. Question 81 Based on the audiogram, which ear demonstrates a greater degree of high-frequency hearing loss? A. Right Ear B. Left Ear C. Equal in both ears D. Neither ear shows loss Correct Answer: A Question 82 If the audiogram was tested using supra-aural headphones with IA of 40 dB, which scenario would require masking during AC testing? A. AC(R) = 55 dB, BC(L) = 15 dB
B. AC(R) = 30 dB, BC(L) = 25 dB C. AC(R) = 25 dB, BC(L) = 10 dB D. AC(L) = 20 dB, BC(R) = 30 dB Correct Answer: A Question 83 What is the primary reason masking would be necessary in this audiogram? A. Asymmetry in low frequencies B. Bilateral severe SNHL C. Risk of crossover due to interaural difference D. Flat hearing configuration Correct Answer: C Question 84
Question 86 What masking error would occur if you mask the left ear at 20 dB while testing 60 dB in the right ear? A. Effective masking B. Overmasking C. Undermasking D. Central masking Correct Answer: C Question 87 If bone conduction in the right ear is measured at 15 dB, and AC in the right ear is 30 dB, what does this suggest? A. Conductive component B. Normal hearing C. Sensorineural loss
D. Equipment error Correct Answer: A Question 88 Why might you expect a masking dilemma when testing BC in the left ear? A. Low-frequency asymmetry B. ABG in both ears C. High-frequency loss only D. IA is too high Correct Answer: B Question 89 When testing right ear AC at 60 dB and the left ear BC is 25 dB, which condition is required to prevent overmasking? A. Use insert earphones B. Decrease IA to 30 dB
