Written midterm examination 10-20%
Lab practical midterm examination 10-20%
Final examination 20-35%
Upon completion of this course, the student will be able to:
1. Explain the internal structures and the functions of a modern hearing aid
2. Explain the differences between hearing aid styles and the limitations for different types of hearing loss
3. Explain the differences in signal processing strategies between analog and digital technology
4. Explain how sound is modified within a hearing aid prior to entering the ear
5. Explain how to test basic hearing aid functions and identify when additional troubleshooting is required
6. Explain how hearing aid fittings can affect sound quality
7. Explain how different physical modifications to hearing aids and earmolds can affect sound
8. Explain the differences between various industry standard hearing aid fitting formulas from past to present
9. Explain the differences in earmold materials used based on degree of hearing loss
10.Explain the different battery sizes available in addition to battery drain calculation
