Hybrid Virtual CAOHC Course

Presented by Earmark Hearing Conservation

Occupational Hearing Conservationists are trained and credentialed through Council for Accreditation in Occupational Hearing Conservation (CAOHC) approved courses. Dr. Wartinger (Course Director #496199) offers high-quality courses with engaging instruction for occupational health professionals who administer audiometric testing as required by OSHA, MSHA, DOD and FRA regulations.

Completion of a CAOHC-approved course, conducted by a CAOHC certified Course Director, does not automatically grant Occupational Hearing Conservation certification. All students must pass a computer-based examination at the conclusion of the course. An application and fee will be submitted to CAOHC on each student's behalf and is included in the published course fee. CAOHC grants certification for five years.

Hybrid Virtual CAOHC Courses offered by Earmark Hearing Conservation require in-person attendance on the 3rd (last) day for audiometric practicum, hearing protection device practicum, and examination. Day 1 and 2 will be entirely online completed from the comfort of your home or office through your browser.

Agenda:

Day 1: 9 AM to 4 PM Online

Day 2: 9 AM to 4 PM Online

Day 3: 10 AM to 4:30 PM In-Person at 301 Lindenwood Dr, Malvern, Pennsylvania 19355

  2. Participate fully – unmute your camera as much as possible, and engage in the conversation
  3. Respect each other’s time – join on time and promptly after breaks
  4. Cut ourselves some slack – virtual learning can be relaxing and enjoyable, just make yourself comfortable and ready to learn

I’ve had the privilege of working in the fire service for over 30 years, earning around 10 certifications along the way. The instructors in this course stood out as exceptionally polite, reassuring, and informative - truly the best I’ve encountered. The virtual format was seamless and effective. I couldn’t find any areas for improvement - the course was outstanding just the way it was!

Wonderful, very informative course. The instructors have a wealth of knowledge and great personalities. I have already recommended these course instructors to my co-workers. I definitely plan to re-certify with them as well.
