According to the Occupational Safety and Health Administration (OSHA) Guidance 29 CFR 1910.95(g)(3):
From this guidance CAOHC has combined the disciplines; audiologist, otolaryngologist, or other physician, into the designation known as the Professional Supervisor of the Audiometric Monitoring Program© (PS). The PS plays a critical role in ensuring the effectiveness of a hearing conservation program. The PS works in conjunction with other professionals, including nurses, occupational hearing conservationists (OHCs), industrial hygienists, safety professionals, employers, employees, and their representatives. The PS is responsible for reviewing problem audiograms and determining whether there is a need for further evaluation.
CAOHC has designed a one day training program to prepare audiologists, otolaryngologists, or other physicians for the Professional Supervisor of the Audiometric Monitoring Program© certification exam.
