New Web Site Offers Resources for NRR Changes

As EPA works to better align Noise Reduction Ratings (NRR) with real-world use of hearing protection, a number of proposed changes to testing, labeling and regulations are underway. The new Web site provides the latest regulatory updates, expert insights and resources for implementing these new regulations into the workplace.

Sponsored by hearing conservation leaders E-A-R, Peltor and 3M, offers news updates as changes are made, answers to frequently asked questions, articles and the opportunity to pose questions to hearing conservation experts, including E-A-R Senior Scientist Elliott Berger, and 3M Technical Advisor Ted Madison.

“There are a number of agencies and steps involved before the changes can go into effect,” explained Berger. “Visitors can learn about the various agencies and organizations involved, including the EPA and ANSI, and better understand how they fit into the regulatory process. They can also see side-by-side comparisons of the old and proposed new labels and the rationale behind the revised standard, which should ultimately make it easier to choose effective hearing protection.”
