In the audiogram above, identify where masking is needed (yes/no) for right BC and what the initial presentation level should be (assume supra-aural headphones). If no masking is needed, write N/A. Right Frequency  Masking needed?   Starting level 4000 Hz        [BLANK-1]                           [BLANK-2]

What would a 1.5-channel audiometer that allows air & bone conduction would be classified as?

Based on the responses below, what would SRT be?SRT.jpg 

In the audiogram above, identify where masking is needed (yes/no) for right BC and what the initial presentation level should be for plateau masking. Assume insert earphones.

Someone with normal hearing precipitously sloping to a severe hearing loss at 4000 Hz would have the most difficulty hearing what phonemes?

Johnny Rose is a 68-year-old male patient complaining of a lifelong hearing loss. He reports dizzy spells accompanied by nausea that occur with some frequency, typically once every two to three months. Pure tone air and bone conduction thresholds reveal hearing sensitivity significantly worse in the mid frequencies than in the high or low frequencies (near normal) with a pure tone average of 40 dB HL. The configuration of this hearing loss would likely be described as which of the following?
