In general, the first half of class time will be lecture-based followed by a break and then hands-on lab or guest speaker.  Lab assignments will be given that coincide with the in-class lecture and in-class labs.  Correspondence regarding any questions regarding the assignments is highly encouraged throughout the week via email.  All assignments will be due at the beginning of class.  Late assignments will not be accepted unless prior arrangements have been made. The first 15 minutes of class each week will be a review of the prior week’s assignment.  There will be a very short quiz at the beginning of each class over the prior week’s lecture and readings.  All assigned readings are expected to be completed prior to class since the basis of the course lectures will be over the readings.

 Course Objectives:

The main objective of this course is to introduce the theories and concepts of today’s technology with regard to amplification systems for hearing impaired clients.  Part of a strong audiological battery for a comprehensive aural rehabilitation and treatment process is knowing and understanding which hearing solutions to offer each hearing impaired individual. 

 This is the first of two courses in amplification systems.  By the end of this course, each student should be able to:

  • Understand the difference between analog and digital circuitry in hearing aids
  • Linear versus non-linear compression methods
  • Apply sound acoustic principles and how they relate to earmold design
  • Verify hearing aid performance electroacoustically
  • Understand various processing strategies and verify each with real-ear measurements
  • Have knowledge of FM systems, Implantable devices and CROS technology for special populations of the hearing impaired


Throughout the course there will be several in-class, group or individual labs.  Deadlines and instructions for these will be given throughout the semester.  These labs are designed for hands-on practical experience that will help you in your daily clinical experiences.
