Frequently Asked Questions

Answers to most questions related to the PS may be found in the PS section of this website. Here are a few of the most common questions that are posed to the CAOHC staff members. 


Q: Is specific training required just to administer the hearing tests?

A: To administer a hearing test, it is highly recommended that the OHC be CAOHC certified. While this is not mandatory, it does ensure that everyone on your staff has been trained in the same manner and that your results are consistent. This is an important protection for the employer.

Q: Is specific training required to oversee a Hearing Conservation program?

A: OSHA mandates that any audiologist, MD or DO (anyone that oversees your hearing conservation program) must be trained as a CAOHC Professional Supervisor (PS). Please refer to the PS section and the ABOUT tab in that section.

Q: Who determines if a hearing loss is work related?

A: According to OSHA, a Professional Supervisor of the Audiometric Monitoring Program™ (PS/A) has the authority to determine the work-relatedness of a hearing loss for purposes of recording hearing loss on the OSHA 300 Log of work related injuries and illnesses.  It is recommended that the PS collaborate and obtain information from  with all members of the hearing conservation team (e.g. Industrial Hygiene, Safety, Human Resources and medical). For more details see the PS Scope of Practice.

Q: How long is my certification valid?

A: The certification for the Professional Supervisor of the Audiometric Monitoring Program (CPS/A) is valid for five years. For those re-certifying, they are eligible to take a recertification option, but must do so before they expire. Once the PS certification has expired, the participant must take the full course again.

Q: Who has the responsibility of keeping track of my certification expiration date? 

A: It is the responsibility of the person who is certified to keep track of their own expiration date.

Q: Do you have to be an audiologist or physician (MD, DO) to take the PS workshop and/or exam?

A: The PS course is intended for audiologists and physicians who supervise and review audiometric testing for hearing conservation programs. Other hearing conservation professionals may participate in this course; however, they are not eligible to take the certification exam.
