In this course, you will learn to perform pure tone air conduction hearing tests and other associated duties of the Occupational Hearing Conservationist (OHC) as a member of the occupational hearing conservation team. All participants will have ample opportunity to practice hearing testing utilizing a variety of audiometry equipment with one-on-one instruction from the faculty. Classroom exams are computer-based and participants will need to bring their own laptop computer to the training for testing.

Registration fee of $725 includes course materials, CAOHC (Council for Accreditation for Occupational Hearing Conservation) manual, processing of your exam, certification application to CAOHC, and CEU certificate.

This is a CAOHC-Approved course.

This course is eligible for 2.0 Continuing Education Units (CEUs) (20 contact hours).

Nurses: This activity has been designed to meet Minnesota Board of Nursing continuing education requirements for 20 (60 minute) contact hours, and ABOHN requirements for certification.

Safety Professionals: This course is designed to meet the criteria for Continuance of Certification (COC) as specified by the Board of Certified Safety Professionals (BCSP).

Offered by the Midwest Center for Occupational Health and Safety (MCOHS).
Supported by the University of Minnesota School of Public Health Learning Innovations Office.


OHCs who complete the CAOHC training course can be, depending upon the program as established by the supervising professional, responsible for the following activities:

  • Visually inspecting the ear to rule out any condition that might interfere with the test.
  • Taking a medical history.
  • Audiometric testing, including baseline, annual and in some cases retesting.
  • Screening the audiograms and selecting problem audiograms for review by the professional supervisor (an audiologist or physician).
  • Referring to the appropriate sources for further testing or medical treatment.
  • Functional check of the audiometer before each use, and making sure that it gets calibrated at the appropriate times.
  • Recordkeeping.
  • Notifying employees of a standard threshold shift in a timely manner once those shifts have been identified by the supervising professional.
  • Educating, training, and counseling employees.
  • Selecting, fitting, and supervising the wearing of hearing protection devices.


As a result of completing this learning activity, you will be able to:

  • demonstrate proficiency in pure tone hearing threshold testing techniques on manual and microprocessor audiometers,
  • describe basic ear anatomy/physiology as well as how to perform an otoscopic exam,
  • list parameters of sound as they relate to hearing testing,
  • list various aspects of industrial hearing conservation programs, employee education, and federal and state regulations, and
  • review updated information regarding current instrumentation and products.
