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 the different methods used by various commercially available fit-testing systems.  Information related to the recently approved ANSI/ASA standard for hearing protector fit-test systems will be shared. During the second part of the session, attendees will experience hands-on demonstrations of the various products.
