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, including passing the computer-based standardized CAOHC examination, will grant attendees with the Occupational Hearing Conservation certification (COHC). An application and exam 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.

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.

Agenda:

Day 1: 9 AM to 4 PM

Day 2: 9 AM to 4 PM *Access to hearing protection devices between 1:30 - 2:30 PM

Day 3: 9 AM to 4 PM

Note: Class times are listed in ET (Eastern Time)

Technology and connection requirements

To attend an online course, each student must have access to the following equipment:

  • Computer (laptop or desktop) with reliable internet connection and a functional webcam. Accessing the course from a tablet or mobile phone device will result in a poor learning experience and may be deemed inappropriate for completing the certification training.
  • Otoscope and a willing individual to serve as a stand-in patient (for a few minutes) during the practicum section on day 2. For participants who are experiences in otoscopic examination, alternative options may be discussed to complete this course requirement.
  • Hearing protection devices (note: a selection of devices will be shipped out to each registrant 1-2 weeks prior to the course date)
  • Access to an audiometer is not required during the course due to the extensive use of online simulators. However, many students report benefit from having access to a physical audiometer device for extended hands-on learning.

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
  • Otoscopic Inspection
  • Federal and State Regulations
  • Employee Education and Motivation
  • Record Keeping and Recordability

Virtual Course Expectations

Virtual learning is new for many of us. For the benefit of everyone’s experience, below are a few 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 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

Manuals and Handouts

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

Each student will receive access to the official online CAOHC Exam Prep study materials ($20 value)

The following items will be shipped to each participant 1-2 weeks prior to the course date:

  • CAOHC Manual 5th edition ($80 value)
  • Hearing Protection Devices - A selection of devices to be used during the practicum ($10 value)
  • Course Handouts and references (priceless)

Otoscope Access

Otoscopic training is required to complete the course. During the course, you will need to have access to an otoscope and a willing individual to serve as a stand-in patient during practicum for a few minutes. If you are concerned you will not have access to an otoscope or another individual, please reach out to your course director for alternative methods to complete this requirement.

Continuing Education Credits

Eligible participants in this course will receive 20 hours of continuing education credits from Earmark Hearing Conservation and the DC Board of Nursing.

We look forward to seeing you in the course!

I highly recommend this CAOHC Certification Course with Earmark Hearing Conservation! Going into a 20-hour training, I expected it to be a long process, but the instructors were so engaging that the time flew by. The material was packed with excellent, highly relevant information, and the instructors always made time to thoroughly answer our questions. Thanks to this course, I walked away with a much deeper understanding of occupational hearing conservation and what my certificate actually entails. Best of all, I was fully prepared and passed my certification test on the first try! Excellent course and fantastic instructors.

All instructors were easy to follow and very informative. It was evident that they truly enjoy teaching this course and want to help each person understand the importance of protecting hearing and preventing hearing loss. This class was enjoyable while educational and I will definitely want to return for my recertification.

I was impressed by your course. The goals were clear and I appreciated how the content was approached from different angles, which aided in greater understanding. I also thought the structure of mixing it up and moving the student group from one instructor to the next helped to keep things fresh and give the feeling of forward momentum. I’m guessing that can be a challenge with this format. Ultimately, I thought the execution was excellent. As someone not from this field I was unsure what to expect and maybe even a little intimidated, but you made the new information and some complex ideas easier to absorb.

But the kicker for me, and perhaps most importantly, in a moment where communicating with each other in a real and meaningful way seems to be eroding more and more every day I found this experiece to be uplifting and even kind of hopeful. I recognize that this is prompt is probably meant more as a forum to discuss the content and execution of the class but I think this plays an important and maybe underappreciated role. Your HUMOR and your willingness to give us (strangers) a glimpse into your humanity, not too much as to be unprofessional, but enough to glimpse things that are important to you. Family, art, music, fairness among others. I think you struck the perfect balance and I applaud you. By doing this you created an environment where the student opens up to learning or absorbing in a way that I’m unsure how to quantify. It’s small, but big and important. Your passion for the field comes through, it’s evident that this is not just a job for you. Ok, I’ll stop now before I get written off as a weirdo. Sorry to be so long winded but I think it’s important to tell each other how we feel, especially when it’s positive. Best to you and yours, sincerely, Chris
