Audiometric Testing Course lead by a Local OSHA/Audio Expert 

Audiometric Testing Course

Did you know if you plan to conduct audiometric testing or are involved with hearing conservation that you must be certified to do so?  

For employers, an effective occupational hearing conservation program (HCP) is implemented to help preserve and protect the hearing of employees who work in jobs that expose them to hazardous noise such as manufacturing, agriculture, mining, military, transportation, construction etc.  

If hazardous noises cannot be eliminated, annual hearing testing must be offered to the employees working in an environment at or above 85 dBA TWA. 

According to OSHA, these programs need to include 6 important elements: 

  1. Noise measurement 
  2. Noise control 
  3. Audiometric testing 
  4. Hearing protection 
  5. Employee education and training 
  6. Recordkeeping 

If you plan on being involved in these elements of the hearing conservation program, you will need to become a Certified Occupational Hearing Conservationist (COHC).  

According to the Occupational Safety & Health Administration (OSHA) 29 Code of Federal Regulation 1910.95(g)(3): 

“Audiometric tests shall be performed by a licensed or certified audiologist, otolaryngologist, or other physician or by a technician who is certified by the Council for Accreditation in Occupational Hearing Conservation or who has satisfactorily demonstrated competence in administering audiometric examinations, obtaining valid audiograms and properly using, maintaining and checking calibration and proper functioning of the audiometers being used.” 

These certified personnel may be audiologists, physicians, occupational health nurses, industrial hygienists, human resources directors, workplace safety officers or any person interested in occupational hearing conservation.  

These people may be responsible for  

  • performing pure tone air conduction audiometric testing 
  • fitting hearing protection devices 
  • providing education, and  
  • enforcing hearing conservation program (HCP) compliance 

So, what does it take to become certified?  

How to become a Certified Occupational Hearing Conservationist 

To become certified, you must complete a 20-hour CAOHC-approved course and pass an exam given at the end of the course.  

The certification course is designed to train personnel: 

  • who will be or are conducting audiometric testing 
  • who are actively involved in hearing conservation, or  
  • who supervise hearing conservation programs 

Upon successful completion of the course, participants are eligible for certification or recertification through CAOHC, which must be renewed every 5 years.  

Completion of a CAOHC-approved course does not automatically grant Occupational Hearing Conservation certification. All students must pass a computer-based examination at the conclusion of the course.
