R&D Portfolio - Research Goal 2.4:
Develop a hearing protection and communication system
HLR program researchers were awarded a U.S. Patent for the EarTalk system in 1991. Research information has been presented and demonstrated at national and international conferences and expositions. Two publications have resulted from the research.
EarTalk technology is available for licensing through CDC technology transfer office. To date, one licensee (Cavcom, Inc.) has incorporated EarTalk into a system that works with Motorola radios commonly used by police and firefighters.
