Case 12 Audiometrics

Here is the audiogram in the format used by this particular clinic.

Below is the audiogram as redrawn with a computer program.

NU-6 word lists

  • The split ear audiogram notes FA as an abbreviation for Fletcher Average. What is the FA and when should it be used? Should it have been used in this case?
  • The unmasked bone conduction test results were retained.  Some clinics put a dot on the unmasked threshold but do not keep those thresholds. Some computer-based audiometers delete the unmasked when the masked threshold is found. Here, there is no reason to keep the unmasked thresholds.  Would there ever be a reason one would want to see the unmasked thresholds?
