Course Description
This course continues to develop concepts learned in earlier lab courses. It builds upon prior knowledge and experience with masking, speech-in-noise testing, acoustic reflex (AR) testing, as well as the testing of oto-acoustic emissions (OAEs). This course also introduces the student to specialized testing done mainly by audiologists to assess retro-cochlear pathology, such as AR decay, the auditory brain stem response (ABR), and testing for central auditory processing disorders (CAPD). While these specialized test assessments are not typically part of the HIP scope of practice, this course enables the student to gain some knowledge about the test procedures.
Course Content
  1. Masking
  2. Speech-in-noise testing
  3. Tympanometry and acoustic reflex testing
  4. Oto-acoustic emissions
  5. Synthesizing test results
  6. Specialized testing done by Audiologists
Learning Outcomes

Upon completion of this course, the student will be able to:


 1. Perform more advanced components of the audiometric test battery

 2. Demonstrate ability to perform masking during audiometry

 3. Produce accurate advanced speech testing results, e.g., speech-in-noise (SIN) test

 4. Interpret advanced speech test results

 5. Perform accurate tympanometry, ipsilateral and contralateral acoustic reflex tests

 6. Interpret tympanometry measures, ipsilateral and contralateral acoustic reflex patterns

 7. Perform testing of oto-acoustic emissions

 8. Modify hearing tests according to the needs of individual clients

 9. Synthesize findings of advanced audiometric procedures with likely sites of pathology

10. Describe testing for acoustic reflex decay and the auditory brain stem response

11. Explain the commonly used test procedure for central auditory processing disorders
