In the audiogram above, identify where masking is needed (yes/no) for left AC and what the initial presentation level should be for plateau masking. Assume supra-aural earphones. If no masking is needed, write N/A. Right Frequency Masking needed?  Starting level 250 Hz    [BLANK-1]              [BLANK-2] 500 Hz    [BLANK-3]              [BLANK-4] 1000 Hz   [BLANK-5]              [BLANK-6] 2000 Hz   [BLANK-7]              [BLANK-8] 3000 Hz   [BLANK-9]              [BLANK-10]

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?

Your patient Pedro Pascal has an SRT of 45 and a PTA of 33.3. What might have happened?

Which picture shows proper otoscopic technique? otoscopy.jpg 

Fletcher’s average should be used with what hearing loss configuration to better match speech reception thresholds?

SRT should agree with PTA within how much?

What is the purpose of masking?

For a person with hearing loss, the most comfortable listening (MCL) level is somewhere between threshold and the uncomfortable loudness level (UCL). The area between threshold and UCL is known as what?

Calibration standards for audiometers in the United States are established by which of the following organizations?
