Research Institution
ANR technologies have been successfully incorporated in communication headsets to improve speech intelligibility and hearing conservation in high noise environments. This Phase I research effort will introduce advancements in optimal controller/headset architectures that will lead to: greater SPL attenuations at the ear, significantly extended ANR bandwidth, and improvements in speech intelligibility for both high and medium intensity noise fields. One circumaural and one open-air headset prototype will be used to demonstrate the expected improvements compared to existing state-of-the-art active and passive headsets. A unique team is in place to complete the research and development tasks. A total of five investigators will provide expertise in personal ANR system design, optimal control theory, adaptive signal processing methods, personal ANR component fabrication, and evaluation methods to assess attenuation and speech intelligibility provided by ANP headsets. BENEFITS: The proposed Phase I program provides the ARMY an opportunity to realize dramatic improvements in the ANR performance for communication systems in noise fields of varied intensities. Improvements realized from this project will be directly applicable to other DOD communication systems and will be directly applicable to commercial headsets in aviation, manufacturing, and numerous other industries.
