What will the program achieve?
Research Goal 2.1 - Develop measurement and rating methods that are representative of real-world performance of hearing protection devices

The HLR program will continue to assist the EPA’s regulatory efforts to update its regulations that reflect current HPD testing methods and to develop a noise reduction rating that is more directly applicable to users in occupational settings.[39] The revised regulation will include testing and rating methods for new technologies such as sound restoration, communication, active noise reduction, integrated radio, and level-dependent passive HPDs. The HLR program has partnered with hearing protection manufacturers, (Aearo/EAR, Bacou-Dalloz and Bose Corporation), the US Army Aeromedical Research Laboratory, US Air Force Wright Patterson Air Force Base, EPA, and various universities to develop recommendations for new technologies, assessment methods and rating recommendations. Through these partnerships the HLR program will continue to lead development of standards in these overlooked technologies.
