eAudiology: Maximum Conductive Hearing Loss - Revisited

View Course Details Please note: exam questions are subject to change.


1.  Audiologists have traditionally had the understanding that maximum conductive hearing loss is about ________ dB, but it can in fact potentially be upwards of ____________ dB.
  1. 60, 105
  2. 45, 85
  3. 60, 75
  4. 85, 120
2.  National Research Council attributes maximum conductive hearing loss to:
  1. Vibrations of the ossicles
  2. Attentive listening
  3. Vibrations of the bones of the skull
  4. All of the above
3.  Based on what Leah shared on the Quora site, her daughter's hearing was likely tested:
  1. Under inserts
  2. Under supra-aural headphones
  3. In sound field
  4. Under circum-aural headphones
4.  The largest interaural attenuation that Sklare and Denenberg obtained on their subjects with single-sided deafness was _______ dB at ______ Hz.
  1. 75, 4000
  2. 105, 500
  3. 120, 2000
  4. 85, 1000
5.  If a patient's interaural attenuation at a given frequency is 80 dB, and his conductive system is entirely closed off, one would expect his air-bone gap at that frequency to be about:
  1. 60 dB
  2. 70 dB
  3. 80 dB
  4. 90 dB
