Virtual CAOHC Recertification 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 recertification. All students must pass a computer-based examination at the conclusion of the course. An application and fee must be submitted to CAOHC, who will grant recertification for five years.

Virtual CAOHC Courses offered by Earmark Hearing Conservation are entirely online with no in-person requirements. Instruction, audiometric practicum, hearing protection device practicum, and examination are all completed through your browser.

Course Topics

• Anatomy and Physiology of the Ear
• The Audiometer and Test Environment
• Audiometric Techniques
• Audiogram Referral and Follow-up
• Principles of Noise Analysis and Control
• Hearing Protection Device Fitting and Training
• Federal and State Regulations

Technology and connection requirements

• Reliable high-speed internet connection
• Access to a computer for the full duration of course. Laptop or desktop computers are preferred for ease of use. Accessing the course on a mobile phone or tablet will likely result in a reduced quality experience.
• Webcam (built-in or external) sufficient for routine video call participation. An active video and microphone connection is a requirement to take the online examination due to the need for effective proctoring. Please discuss technology exceptions with your course director.

Virtual Course Expectations

1. Focus on the course – reduce virtual and real-world distraction
2. Participate fully – unmute your camera as much as possible, and engage in the chat as though you are in a real classroom
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

Many of the course resources and downloads are available online at http://www.earmarkhc.com/caohc-course-resources.
