  • There will be one participant per table to assure adequate distancing, or at least 6 feet separation at all times.
  • All participants will be required to wear masks during the course.
  • Participants will be encouraged to exercise social distancing during the course and during breaks.
  • Participants are encouraged to hand wash as much as possible; liquid hand sanitizer and wet wipes will be available.

  • The classroom will be sanitized after each class day;
  • During the audiometric practicum, whereby hearing tests are conducted on each other, partners will maintain a minimum 6 foot distance.  Earphone cords are long enough to ensure necessary distancing;
  • After each use, audiometer face panels and earphones will be sanitized with wet wipes;
  • For the earplug fitting practicum, instruction will be given on how to properly insert an earplug, and participants will be doing a self-fit on a variety of hearing protection devices;
  • Prior to the earplug fitting practicum, a video otoscope will be used by each participant to view the condition of their ear before any earplug insertion.  Images will be viewed on an iPad for all to see.  Between use, the otoscope will be sanitized with wet wipes, and disposable speculums will be used.

Please plan on bringing pen(s), highlighter, and notepad; none of these items will be provided.

Upon completion and a passing score on the final examination, a Certificate of Completion will be issued to registrants. CAOHC certification fee is included in your registration free.



There will be a certification and re-certification exam at the end of each course.  The Council for Accreditation in Occupational Hearing Conservation (CAOHC) is no longer using test booklets to conduct the exam.  Rather, CAOHC is now requiring that participants bring either a laptop/notebook (preferred) or a tablet to the course to take the exam online proctored by the Course Director.  The exam can only be taken using either Mozilla Firefox or Chrome browsers.  When you bring your device, you are strongly encouraged to establish a WiFi connection as soon as possible to ensure that you can take the exam without interruption.

Registration fees include course materials, CEUs & CAOHC Certificates. Full attendance is required - no partial credit will be awarded.
It is the licensee’s responsibility to determine if this education program meets the requirements of their professional licensure board.
