Course Description
This course reviews concepts learned in the introductory course on audiometry, and expands on them considerably. Specifically, it covers not only the topic of when to use masking, but also how to perform masking. We will examine various types of advanced speech testing materials, such as speech-in-noise (SIN) testing procedures. We will also look further into the topic of tympanometry, including the acoustic reflex.

Learning Outcomes
Upon completion of this course, the student will be able to:
- Describe the components of the basic audiometric test battery
- Identify when to apply the use of masking for audiometry
- Demonstrate ability to perform masking during audiometry
- Produce accurate routine speech testing results; e.g., most comfortable loudness (MCL), speech-reception threshold (SRT), speech-discrimination (SD), and uncomfortable loudness (UCL)
- Interpret routine speech testing results
- Produce accurate advanced speech testing results; e.g., speech-in-noise (SIN) test or acceptable noise level (ANL) test
- Interpret advanced speech testing results
- Perform accurate tympanometry and ipsilateral and contralateral acoustic reflex test results
- Interpret obtained tympanometry measures and ipsilateral & contralateral acoustic reflex patterns
- Modify hearing tests according to the needs of individual clients
- Implement strategies of testing for suspected pseudohypacusis
- Synthesize findings of advanced audiometric procedures with likely sites of pathology
