Intro to Immittance & OAE

This site presents case studies in audiology, organized by the tabs to the right.

The cases use problem-based learning strategies. Students are encouraged to research questions if the  material has not yet been included in coursework.

These cases are designed to do the following

  • Show the use of otoacoustic emissions testing in substantiating the presence of hearing loss.
  • Reinforce immittance data interpretation is featured.  Students must have an understanding of what constitutes a normal / abnormal acoustic reflex threshold and be able to calculate reflex sensation level to successfully navigate these cases.  The use of immittance in establishing site of lesion is highlighted.
  • Review tympanometric width calculation and its use
  • Introduce case management strategies.

Some amplification topics are presented, but coursework in amplification is not required for this case studies series.
