NHCA/CAOHC Webinar Series: Hearing Protector Fit Testing

The National Hearing Conservation Association (NHCA) has coordinated with the Council for Accreditation in Occupational Hearing Conservation (CAOHC) to host another NHCA/CAOHC webinar series for 2021. 

The live program aired on 04/8/21.

About the Webinar:  For over 30 years, hearing conservation professionals have known that the Noise Reduction Rating is not necessarily representative of the protection afforded to the average user of hearing protection. This workshop will present an overview of the technologies available to the hearing conservation professional. During the first part of the session, attendees will learn about different methods to implement fit-testing, benefits of conducting fit testing, and the different methods used by various commercially available fit-testing systems. Information related to the recently approved ANSI/ASA S12.71-2018 performance criteria for standard for hearing protector fit-test systems will be shared.
